+BertGeneration
+----------------------------------------------------
+
+Overview
+~~~~~~~~~~~~~~~~~~~~~
+
+The BertGeneration model is a BERT model that can be leveraged for sequence-to-sequence tasks using :class:`~transformers.EncoderDecoderModel` as proposed in `Leveraging Pre-trained Checkpoints for Sequence Generation Tasks <https://arxiv.org/abs/1907.12461>`__ by Sascha Rothe, Shashi Narayan, Aliaksei Severyn.
+
+The abstract from the paper is the following:
+
+*Unsupervised pre-training of large neural models has recently revolutionized Natural Language Processing. By warm-starting from the publicly released checkpoints, NLP practitioners have pushed the state-of-the-art on multiple benchmarks while saving significant amounts of compute time. So far the focus has been mainly on the Natural Language Understanding tasks. In this paper, we demonstrate the efficacy of pre-trained checkpoints for Sequence Generation. We developed a Transformer-based sequence-to-sequence model that is compatible with publicly available pre-trained BERT, GPT-2 and RoBERTa checkpoints and conducted an extensive empirical study on the utility of initializing our model, both encoder and decoder, with these checkpoints. Our models result in new state-of-the-art results on Machine Translation, Text Summarization, Sentence Splitting, and Sentence Fusion.*
+
+Usage:
+
+- The model can be used in combination with the :class:`~transformers.EncoderDecoderModel` to leverage two bert pretrained bert checkpoints for subsequent fine-tuning.
+
+::
+  
+  # leverage checkpoints for Bert2Bert model...
+  encoder = BertGenerationEncoder.from_pretrained("bert-large-uncased", bos_token_id=101, eos_token_id=102)  # use BERT's cls token as BOS token and sep token as EOS token
+  decoder = BertGenerationDecoder.from_pretrained("bert-large-uncased", add_cross_attention=True, is_decoder=True, bos_token_id=101, eos_token_id=102)  # add cross attention layers and use BERT's cls token as BOS token and sep token as EOS token
+  bert2bert = EncoderDecoderModel(encoder=encoder, decoder=decoder)
+  
+  # create tokenizer...
+  tokenizer = BertTokenizer.from_pretrained("bert-large-uncased")
+
+  input_ids = tokenizer('This is a long article to summarize', add_special_tokens=False, return_tensors="pt").input_ids
+  labels = tokenizer('This is a short summary', return_tensors="pt").input_ids
+
+  # train...
+  loss = bert2bert(input_ids=input_ids, decoder_input_ids=labels, labels=labels, return_dict=True).loss
+  loss.backward()
+
+
+- Pretrained :class:`~transformers.EncoderDecoderModel` are also directly available in the model hub, *e.g.*:
+
+
+::
+
+  # instantiate sentence fusion model
+  sentence_fuser = EncoderDecoderModel.from_pretrained("google/roberta2roberta_L-24_discofuse")
+  tokenizer = AutoTokenizer.from_pretrained("google/roberta2roberta_L-24_discofuse")
+
+  input_ids = tokenizer('This is the first sentence. This is the second sentence.', add_special_tokens=False, return_tensors="pt").input_ids
+
+  outputs = sentence_fuser.generate(input_ids)
+
+  print(tokenizer.decode(outputs[0]))
+
+
+Tips:
+
+- :class:`~transformers.BertGenerationEncoder` and :class:`~transformers.BertGenerationDecoder`  should be used in combination with :class:`~transformers.EncoderDecoder`.
+- For summarization, sentence splitting, sentence fusion and translation, no special tokens are required for the input. Therefore, no EOS token should be added to the end of the input.

+Funnel Transformer
+------------------
+
+Overview
+~~~~~~~~~~~~~~~~~~~~~
+
+The Funnel Transformer model was proposed in the paper
+`Funnel-Transformer: Filtering out Sequential Redundancy for Efficient Language Processing
+<https://arxiv.org/abs/2006.03236>`__.
+It is a bidirectional transformer model, like BERT, but with a pooling operation after each block of layers, a bit
+like in traditional convolutional neural networks (CNN) in computer vision.
+
+The abstract from the paper is the following:
+
+*With the success of language pretraining, it is highly desirable to develop more efficient architectures of good
+scalability that can exploit the abundant unlabeled data at a lower cost. To improve the efficiency, we examine the
+much-overlooked redundancy in maintaining a full-length token-level presentation, especially for tasks that only
+require a single-vector presentation of the sequence. With this intuition, we propose Funnel-Transformer which
+gradually compresses the sequence of hidden states to a shorter one and hence reduces the computation cost. More
+importantly, by re-investing the saved FLOPs from length reduction in constructing a deeper or wider model, we further
+improve the model capacity. In addition, to perform token-level predictions as required by common pretraining
+objectives, Funnel-Transformer is able to recover a deep representation for each token from the reduced hidden sequence
+via a decoder. Empirically, with comparable or fewer FLOPs, Funnel-Transformer outperforms the standard Transformer on
+a wide variety of sequence-level prediction tasks, including text classification, language understanding, and reading
+comprehension.*
+
+Tips:
+
+- Since Funnel Transformer uses pooling, the sequence length of the hidden states changes after each block of layers.
+  The base model therefore has a final sequence length that is a quarter of the original one. This model can be used
+  directly for tasks that just require a sentence summary (like sequence classification or multiple choice). For other
+  tasks, the full model is used; this full model has a decoder that upsamples the final hidden states to the same
+  sequence length as the input.
+- The Funnel Transformer checkpoints are all available with a full version and a base version. The first ones should
+  be used for :class:`~transformers.FunnelModel`, :class:`~transformers.FunnelForPreTraining`,
+  :class:`~transformers.FunnelForMaskedLM`, :class:`~transformers.FunnelForTokenClassification` and
+  class:`~transformers.FunnelForQuestionAnswering`. The second ones should be used for
+  :class:`~transformers.FunnelBaseModel`, :class:`~transformers.FunnelForSequenceClassification` and
+  :class:`~transformers.FunnelForMultipleChoice`.
+
+The original code can be found `here <https://github.com/laiguokun/Funnel-Transformer>`_.

+

+~~~~~~~~~~~~~~~~~~~~~
+
+The LXMERT model was proposed in `LXMERT: Learning Cross-Modality Encoder Representations from Transformers <https://arxiv.org/abs/1908.07490>`__
+by Hao Tan & Mohit Bansal. It is a series of bidirectional transformer encoders (one for the vision modality, one for the language modality, and then one to fuse both modalities)
+pre-trained using a combination of masked language modeling, visual-language text alignment, ROI-feature regression, masked visual-attribute modeling, masked visual-object modeling, and visual-question answering objectives.
+The pretraining consists of multiple multi-modal datasets: MSCOCO, Visual-Genome + Visual-Genome Question Answering, VQA 2.0, and GQA.
+
+The abstract from the paper is the following:
+
+*Vision-and-language reasoning requires an understanding of visual concepts, language semantics, and, most importantly, the alignment and relationships between these two
+modalities. We thus propose the LXMERT
+(Learning Cross-Modality Encoder Representations from Transformers) framework to learn
+these vision-and-language connections. In
+LXMERT, we build a large-scale Transformer
+model that consists of three encoders: an object relationship encoder, a language encoder,
+and a cross-modality encoder. Next, to endow our model with the capability of connecting vision and language semantics, we
+pre-train the model with large amounts of
+image-and-sentence pairs, via five diverse representative pre-training tasks: masked language modeling, masked object prediction
+(feature regression and label classification),
+cross-modality matching, and image question answering. These tasks help in learning both intra-modality and cross-modality relationships. After fine-tuning from our pretrained parameters, our model achieves the
+state-of-the-art results on two visual question answering datasets (i.e., VQA and GQA).
+We also show the generalizability of our pretrained cross-modality model by adapting it to
+a challenging visual-reasoning task, NLVR
+,
+and improve the previous best result by 22%
+absolute (54% to 76%). Lastly, we demonstrate detailed ablation studies to prove that
+both our novel model components and pretraining strategies significantly contribute to
+our strong results; and also present several
+attention visualizations for the different encoders*
+
+Tips:
+
+- Bounding boxes are not necessary to be used in the visual feature embeddings, any kind of visual-spacial features will work.
+- Both the language hidden states and the visual hidden states that LXMERT outputs are passed through the cross-modality layer, so they
+  contain information from both modalities. To access a modality that only attends to itself, select the vision/language hidden states from the first input in the tuple.
+- The bi-directional cross-modality encoder attention only returns attention values when the language modality is used as the input and the vision modality is used as the context vector. Further,
+  while the cross-modality encoder contains self-attention for each respective modality and cross-attention, only the cross attention is returned and both self attention outputs are disregarded.

+`Funnel-Transformer: Filtering out Sequential Redundancy for Efficient Language Processing
+<https://arxiv.org/abs/2006.03236>`_, Zihang Dai et al.
+
+Funnel Transformer is a transformer model using pooling, a bit like a ResNet model: layers are grouped in blocks, and
+at the beginning of each block (except the first one), the hidden states are pooled among the sequence dimension. This
+way, their length is divided by 2, which speeds up the computation of the next hidden states. All pretrained models
+have three blocks, which means the final hidden state has a sequence length that is one fourth of the original sequence
+length.
+
+For tasks such as classification, this is not a problem, but for tasks like masked language modeling or token
+classification, we need a hidden state with the same sequence length as the original input. In those cases, the final
+hidden states are upsampled to the input sequence length and go through two additional layers. That's why there are two
+versions of each checkpoint. The version suffixed with "-base" contains only the three blocks, while the version
+without that suffix contains the three blocks and the upsampling head with its additional layers.
+
+The pretrained models available use the same pretraining objective as ELECTRA.
+
+The library provides a version of the model for masked language modeling, token classification, sentence
+classification, multiple choice classification and question answering.

+# ParsBERT (v2.0)
+A Transformer-based Model for Persian Language Understanding
+
+
+We reconstructed the vocabulary and fine-tuned the ParsBERT v1.1 on the new Persian corpora in order to provide some functionalities for using ParsBERT in other scopes!
+Please follow the [ParsBERT](https://github.com/hooshvare/parsbert) repo for the latest information about previous and current models.
+
+## Introduction
+
+ParsBERT is a monolingual language model based on Google’s BERT architecture. This model is pre-trained on large Persian corpora with various writing styles from numerous subjects (e.g., scientific, novels, news) with more than `3.9M` documents, `73M` sentences, and `1.3B` words.
+ 
+Paper presenting ParsBERT: [arXiv:2005.12515](https://arxiv.org/abs/2005.12515)
+
+## Intended uses & limitations
+
+You can use the raw model for either masked language modeling or next sentence prediction, but it's mostly intended to
+be fine-tuned on a downstream task. See the [model hub](https://huggingface.co/models?search=bert-fa) to look for
+fine-tuned versions on a task that interests you.
+
+
+### How to use
+
+#### TensorFlow 2.0
+
+```python
+from transformers import AutoConfig, AutoTokenizer, TFAutoModel
+
+config = AutoConfig.from_pretrained("HooshvareLab/bert-fa-base-uncased")
+tokenizer = AutoTokenizer.from_pretrained("HooshvareLab/bert-fa-base-uncased")
+model = TFAutoModel.from_pretrained("HooshvareLab/bert-fa-base-uncased")
+
+text = "ما در هوشواره معتقدیم با انتقال صحیح دانش و آگاهی، همه افراد میتوانند از ابزارهای هوشمند استفاده کنند. شعار ما هوش مصنوعی برای همه است."
+tokenizer.tokenize(text)
+
+>>> ['ما', 'در', 'هوش', '##واره', 'معتقدیم', 'با', 'انتقال', 'صحیح', 'دانش', 'و', 'اگاهی', '،', 'همه', 'افراد', 'میتوانند', 'از', 'ابزارهای', 'هوشمند', 'استفاده', 'کنند', '.', 'شعار', 'ما', 'هوش', 'مصنوعی', 'برای', 'همه', 'است', '.']
+```
+
+#### Pytorch
+
+```python
+from transformers import AutoConfig, AutoTokenizer, AutoModel
+
+config = AutoConfig.from_pretrained("HooshvareLab/bert-fa-base-uncased")
+tokenizer = AutoTokenizer.from_pretrained("HooshvareLab/bert-fa-base-uncased")
+model = AutoModel.from_pretrained("HooshvareLab/bert-fa-base-uncased")
+```
+
+## Training
+
+ParsBERT trained on a massive amount of public corpora ([Persian Wikidumps](https://dumps.wikimedia.org/fawiki/), [MirasText](https://github.com/miras-tech/MirasText)) and six other manually crawled text data from a various type of websites ([BigBang Page](https://bigbangpage.com/) `scientific`, [Chetor](https://www.chetor.com/) `lifestyle`, [Eligasht](https://www.eligasht.com/Blog/) `itinerary`,  [Digikala](https://www.digikala.com/mag/) `digital magazine`, [Ted Talks](https://www.ted.com/talks) `general conversational`, Books `novels, storybooks, short stories from old to the contemporary era`).
+
+As a part of ParsBERT methodology, an extensive pre-processing combining POS tagging and WordPiece segmentation was carried out to bring the corpora into a proper format.
+
+## Goals
+Objective goals during training are as below (after 300k steps).
+
+``` bash
+***** Eval results *****
+global_step = 300000
+loss = 1.4392426
+masked_lm_accuracy = 0.6865794
+masked_lm_loss = 1.4469004
+next_sentence_accuracy = 1.0

+
+## Eval results
+
+ParsBERT is evaluated on three NLP downstream tasks: Sentiment Analysis (SA), Text Classification, and Named Entity Recognition (NER). For this matter and due to insufficient resources, two large datasets for SA and two for text classification were manually composed, which are available for public use and benchmarking. ParsBERT outperformed all other language models, including multilingual BERT and other hybrid deep learning models for all tasks, improving the state-of-the-art performance in Persian language modeling.

+
+## Model description
+
+BART for extractive (span-based) question answering, trained on Squad 2.0.
+
+F1 score of 87.4.
+
+## Intended uses & limitations
+
+Unfortunately, the Huggingface auto-inference API won't run this model, so if you're attempting to try it through the input box above and it complains, don't be discouraged!
+
+#### How to use
+
+Here's a quick way to get question answering running locally:
+
+```python
+from transformers import AutoTokenizer, AutoModelForQuestionAnswering
+
+tokenizer = AutoTokenizer.from_pretrained("Primer/bart-squad2")
+model = AutoModelForQuestionAnswering.from_pretrained("Primer/bart-squad2")
+model.to('cuda'); model.eval()
+
+def answer(question, text):
+    seq = '<s>' +  question + ' </s> </s> ' + text + ' </s>'
+    tokens = tokenizer.encode_plus(seq, return_tensors='pt', padding='max_length', max_length=1024)
+    input_ids = tokens['input_ids'].to('cuda')
+    attention_mask = tokens['attention_mask'].to('cuda')
+    start, end, _ = model(input_ids, attention_mask=attention_mask)
+    start_idx = int(start.argmax().int())
+    end_idx =  int(end.argmax().int())
+    print(tokenizer.decode(input_ids[0, start_idx:end_idx]).strip())
+    # ^^ it will be an empty string if the model decided "unanswerable"
+
+>>> question = "Where does Tom live?"
+>>> context = "Tom is an engineer in San Francisco."
+>>> answer(question, context)
+San Francisco
+```
+
+(Just drop the `.to('cuda')` stuff if running on CPU).
+
+#### Limitations and bias
+
+Unknown, no further evaluation has been performed. In a technical sense one big limitation is that it's 1.6G 😬
+
+## Training procedure
+
+`run_squad.py` with:
+
+|param|value|
+|---|---|
+|batch size|8|
+|max_seq_length|1024|
+|learning rate|1e-5|
+|epochs|2|

+## Model description
+
+Cased BERT model for Hungarian, trained on the (filtered, deduplicated) Hungarian subset of the Common Crawl and a snapshot of the Hungarian Wikipedia.
+
+## Intended uses & limitations
+
+The model can be used as any other (cased) BERT model. It has been tested on the chunking and
+named entity recognition tasks and set a new state-of-the-art on the former.
+
+## Training
+
+Details of the training data and procedure can be found in the PhD thesis linked below. (With the caveat that it only contains preliminary results
+based on the Wikipedia subcorpus. Evaluation of the full model will appear in a future paper.)
+
+## Eval results
+
+When fine-tuned (via `BertForTokenClassification`) on chunking and NER, the model outperforms multilingual BERT, achieves state-of-the-art results on the
+former task and comes within 0.5% F1 to the SotA on the latter. The exact scores are

+
+# Sentence-Doctor
+Sentence doctor is a T5 model that attempts to correct the errors or mistakes found in sentences. Model works on English, German and French text.
+
+## 1. Problem:
+Many NLP models depend on tasks like *Text Extraction Libraries, OCR, Speech to Text libraries* and **Sentence Boundary Detection**
+As a consequence errors caused by these tasks in your NLP pipeline can affect the quality of models in applications. Especially since models are often trained on **clean** input.
+
+## 2. Solution:
+Here we provide a model that **attempts** to reconstruct sentences based on the its context (sourrounding text). The task is pretty straightforward:
+* `Given an "erroneous" sentence, and its context, reconstruct the "intended" sentence`.
+
+## 3. Use Cases:
+* Attempt to repair noisy sentences that where extracted with OCR software or text extractors.
+* Attempt to repair sentence boundaries.
+  * Example (in German): **Input: "und ich bin im**", 
+    * Prefix_Context: "Hallo! Mein Name ist John", Postfix_Context: "Januar 1990 geboren."
+    * Output: "John und ich bin im Jahr 1990 geboren"
+* Possibly sentence level spelling correction -- Although this is not the intended use.
+ * Input: "I went to church **las yesteday**" => Output: "I went to church last Sunday".
+ 
+## 4. Disclaimer
+Note how we always emphises on the word *attempt*. The current version of the model was only trained on **150K** sentences from the tatoeba dataset: https://tatoeba.org/eng. (50K per language -- En, Fr, De).
+Hence, we strongly encourage you to finetune the model on your dataset. We might release a version trained on more data.
+
+## 5. Datasets
+We generated synthetic data from the tatoeba dataset: https://tatoeba.org/eng. Randomly applying different transformations on words and characters based on some probabilities. The datasets are available in the data folder (where **sentence_doctor_dataset_300K** is a larger dataset with 100K sentences for each language).
+
+## 6. Usage
+
+### 6.1 Preprocessing
+* Let us assume we have the following text (Note that there are no punctuation marks in the text):
+
+```python
+text = "That is my job I am a medical doctor I save lives"
+```
+* You decided extract the sentences and for some obscure reason, you obtained these sentences:
+
+```python
+sentences = ["That is my job I a", "m a medical doct", "I save lives"]
+```
+* You now wish to correct the sentence **"m a medical doct"**.
+
+Here is the single preprocessing step for the model:
+
+```python
+input_text = "repair_sentence: " + sentences[1] + " context: {" + sentences[0] + "}{" + sentences[2] + "} </s>"
+```
+
+**Explanation**:</br>
+* We are telling the model to repair the sentence with the prefix "repair_sentence: "
+* Then append the sentence we want to repair **sentence[1]** which is "m a medical doct"
+* Next we give some context to the model. In the case, the context is some text that occured before the sentence and some text that appeard after the sentence in the original text.
+ * To do that, we append the keyword "context :"
+ * Append **{sentence[0]}** "{That is my job I a}". (Note how it is sourrounded by curly braces).
+ * Append **{sentence[2]}** "{I save lives}". 
+* At last we tell the model this is the end of the input with </s>.
+
+```python
+print(input_text) # repair_sentence: m a medical doct context: {That is my job I a}{or I save lives} </s>
+```
+
+<br/>
+
+**The context is optional**, so the input could also be ```repair_sentence: m a medical doct context: {}{} </s>```
+
+### 6.2 Inference
+
+```python
+
+from transformers import AutoTokenizer, AutoModelWithLMHead
+
+tokenizer = AutoTokenizer.from_pretrained("flexudy/t5-base-multi-sentence-doctor")
+
+model = AutoModelWithLMHead.from_pretrained("flexudy/t5-base-multi-sentence-doctor")
+
+input_text = "repair_sentence: m a medical doct context: {That is my job I a}{or I save lives} </s>"
+
+input_ids = tokenizer.encode(input_text, return_tensors="pt")
+
+outputs = model.generate(input_ids, max_length=32, num_beams=1)
+
+sentence = tokenizer.decode(outputs[0], skip_special_tokens=True, clean_up_tokenization_spaces=True)
+
+assert sentence == "I am a medical doctor."
+```
+
+## 7. Fine-tuning
+We also provide a script `train_any_t5_task.py` that might help you fine-tune any Text2Text Task with T5. We added #TODO comments all over to help you use train with ease. For example:
+
+```python
+# TODO Set your training epochs
+config.TRAIN_EPOCHS = 3
+``` 
+If you don't want to read the #TODO comments, just pass in your data like this
+
+```python
+# TODO Where is your data ? Enter the path
+trainer.start("data/sentence_doctor_dataset_300.csv")
+```
+and voila!! Please feel free to correct any mistakes in the code and make a pull request.
+

+* [Huggingface](https://huggingface.co/) transformer lib for making this possible
+* Abhishek Kumar Mishra's transformer [tutorial](https://github.com/abhimishra91/transformers-tutorials/blob/master/transformers_summarization_wandb.ipynb) on text summarisation. Our training code is just a modified version of their code. So many thanks.
+* We finetuned this model from the huggingface hub: WikinewsSum/t5-base-multi-combine-wiki-news. Thanks to the [authors](https://huggingface.co/WikinewsSum)
+* We also read a lot of work from [Suraj Patil](https://github.com/patil-suraj)
+* No one has been forgotten, hopefully :)

+# Turkish Language Models with Huggingface's Transformers
+
+As R&D Team at Loodos, we release cased and uncased versions of most recent language models for Turkish. More details about pretrained models and evaluations on downstream tasks can be found [here (our repo)](https://github.com/Loodos/turkish-language-models).
+
+# Turkish ALBERT-Base (uncased)
+
+This is ALBERT-Base model which has 12 repeated encoder layers with 768 hidden layer size trained on uncased Turkish dataset.
+
+## Usage
+
+Using AutoModel and AutoTokenizer from Transformers, you can import the model as described below.
+
+```python
+from transformers import AutoModel, AutoTokenizer
+
+tokenizer = AutoTokenizer.from_pretrained("loodos/albert-base-turkish-uncased", do_lower_case=False, keep_accents=True)
+
+model = AutoModel.from_pretrained("loodos/albert-base-turkish-uncased")
+ 
+normalizer = TextNormalization()
+normalized_text = normalizer.normalize(text, do_lower_case=True, is_turkish=True)
+
+tokenizer.tokenize(normalized_text)
+```
+
+### Notes on Tokenizers
+Currently, Huggingface's tokenizers (which were written in Python) have a bug concerning letters "ı, i, I, İ" and non-ASCII Turkish specific letters. There are two reasons.
+
+1- Vocabulary and sentence piece model is created with NFC/NFKC normalization but tokenizer uses NFD/NFKD. NFD/NFKD normalization changes text that contains Turkish characters I-ı, İ-i, Ç-ç, Ö-ö, Ş-ş, Ğ-ğ, Ü-ü. This causes wrong tokenization, wrong training and loss of information. Some tokens are never trained.(like "şanlıurfa", "öğün", "çocuk" etc.) NFD/NFKD normalization is not proper for Turkish.
+
+2- Python's default ```string.lower()``` and ```string.upper()``` make the conversions
+
+- "I" and "İ" to 'i'
+- 'i' and 'ı' to 'I'
+
+respectively. However, in Turkish, 'I' and 'İ' are two different letters. 
+
+We opened an [issue](https://github.com/huggingface/transformers/issues/6680) in Huggingface's github repo about this bug. Until it is fixed, in case you want to train your model with uncased data, we provide a simple text normalization module (`TextNormalization()` in the code snippet above) in our [repo](https://github.com/Loodos/turkish-language-models).

+# Longformer2Roberta Summarization with 🤗 EncoderDecoder Framework
+
+This model is a Longformer2Roberta model fine-tuned on summarization.
+
+Longformer2Roberta is a `EncoderDecoderModel`, meaning that both the encoder is a `allenai/longformer-base-4096` model and the decoder is a `roberta-base` model. Leveraging the [EncoderDecoderFramework](https://huggingface.co/transformers/model_doc/encoderdecoder.html#encoder-decoder-models), the 
+two pretrained models can simply be loaded into the framework via:
+
+```python
+roberta2roberta = EncoderDecoderModel.from_encoder_decoder_pretrained("allenai/longformer-base-4096", "roberta-base")
+```
+
+The decoder of an `EncoderDecoder` model needs cross-attention layers and usually makes use of causal 
+masking for auto-regressiv generation.
+Thus, ``longformer2roberta`` is consequently fined-tuned on the `CNN/Daily Mail`dataset and the resulting model
+`longformer2roberta-cnn_dailymail-fp16` is uploaded here.
+
+## Example
+
+The model is by no means a state-of-the-art model, but nevertheless 
+produces reasonable summarization results. It was mainly fine-tuned 
+as a proof-of-concept for the 🤗 EncoderDecoder Framework.
+
+The model can be used as follows:
+
+```python
+from transformers import LongformerTokenizer, EncoderDecoderModel
+
+model = EncoderDecoderModel.from_pretrained("patrickvonplaten/longformer2roberta-cnn_dailymail-fp16")
+tokenizer = LongformerTokenizer.from_pretrained("allenai/longformer-base-4096")

+article = """(CNN)James Holmes made his introduction to the world in a Colorado cinema filled with spectators watching a midnight showing of the new Batman movie, "The Dark Knight Rises," in June 2012. The moment became one of the deadliest shootings in U.S. history. Holmes is accused of opening fire on the crowd, killing 12 people and injuring or maiming 70 others in Aurora, a suburb of Denver. Holmes appeared like a comic book character: He resembled the Joker, with red-orange hair, similar to the late actor Heath Ledger\'s portrayal of the villain in an earlier Batman movie, authorities said. But Holmes was hardly a cartoon. Authorities said he wore body armor and carried several guns, including an AR-15 rifle, with lots of ammo. He also wore a gas mask. Holmes says he was insane at the time of the shootings, and that is his legal defense and court plea: not guilty by reason of insanity. Prosecutors aren\'t swayed and will seek the death penalty. Opening statements in his trial are scheduled to begin Monday. Holmes admits to the shootings but says he was suffering "a psychotic episode" at the time,  according to court papers filed in July 2013 by the state public defenders, Daniel King and Tamara A. Brady. Evidence "revealed thus far in the case supports the defense\'s position that Mr. Holmes suffers from a severe mental illness and was in the throes of a psychotic episode when he committed the acts that resulted in the tragic loss of life and injuries sustained by moviegoers on July 20, 2012," the public defenders wrote. Holmes no longer looks like a dazed Joker, as he did in his first appearance before a judge in 2012. He appeared dramatically different in January when jury selection began for his trial: 9,000 potential jurors were summoned for duty, described as one of the nation\'s largest jury calls. Holmes now has a cleaner look, with a mustache, button-down shirt and khaki pants. In January, he had a beard and eyeglasses. If this new image sounds like one of an academician, it may be because Holmes, now 27, once was one. Just before the shooting, Holmes was a doctoral student in neuroscience, and he was studying how the brain works, with his schooling funded by a U.S. government grant. Yet for all his learning, Holmes apparently lacked the capacity to command his own mind, according to the case against him. A jury will ultimately decide Holmes\' fate. That panel is made up of 12 jurors and 12 alternates. They are 19 women and five men, and almost all are white and middle-aged. The trial could last until autumn. When jury summonses were issued in January, each potential juror stood a 0.2% chance of being selected, District Attorney George Brauchler told the final jury this month. He described the approaching trial as "four to five months of a horrible roller coaster through the worst haunted house you can imagine." The jury will have to render verdicts on each of the 165 counts against Holmes, including murder and attempted murder charges. Meanwhile, victims and their relatives are challenging all media outlets "to stop the gratuitous use of the name and likeness of mass killers, thereby depriving violent individuals the media celebrity and media spotlight they so crave," the No Notoriety group says. They are joined by victims from eight other mass shootings in recent U.S. history. Raised in central coastal California and in San Diego, James Eagan Holmes is the son of a mathematician father noted for his work at the FICO firm that provides credit scores and a registered nurse mother, according to the U-T San Diego newspaper. Holmes also has a sister, Chris, a musician, who\'s five years younger, the newspaper said. His childhood classmates remember him as a clean-cut, bespectacled boy with an "exemplary" character who "never gave any trouble, and never got in trouble himself," The Salinas Californian reported. His family then moved down the California coast, where Holmes grew up in the San Diego-area neighborhood of Rancho Peñasquitos, which a neighbor described as "kind of like Mayberry," the San Diego newspaper said. Holmes attended Westview High School, which says its school district sits in "a primarily middle- to upper-middle-income residential community." There, Holmes ran cross-country, played soccer and later worked at a biotechnology internship at the Salk Institute and Miramar College, which attracts academically talented students. By then, his peers described him as standoffish and a bit of a wiseacre, the San Diego newspaper said. Holmes attended college fairly close to home, in a neighboring area known as Southern California\'s "inland empire" because it\'s more than an hour\'s drive from the coast, in a warm, low-desert climate. He entered the University of California, Riverside, in 2006 as a scholarship student. In 2008 he was a summer camp counselor for disadvantaged children, age 7 to 14, at Camp Max Straus, run by Jewish Big Brothers Big Sisters of Los Angeles. He graduated froLine truncated

+# Model name
+Magic The Generating
+
+## Model description
+
+This is a fine tuned GPT-2 model trained on a corpus of all available English language Magic the Gathering card flavour texts.
+
+## Intended uses & limitations
+
+This is intended only for use in generating new, novel, and sometimes surprising, MtG like flavour texts.
+
+#### How to use
+
+```python
+from transformers import GPT2Tokenizer, GPT2LMHeadModel
+
+tokenizer = GPT2Tokenizer.from_pretrained("rjbownes/Magic-The-Generating")
+
+model = GPT2LMHeadModel.from_pretrained("rjbownes/Magic-The-Generating")
+
+```
+
+#### Limitations and bias
+
+The training corpus was surprisingly small, only ~29000 cards, I had suspected there were more. This might mean there is a real limit to the number of entirely original strings this will generate.
+This is also only based on the 117M parameter GPT2, it's a pretty obvious upgrade to retrain with medium, large or XL models. However, despite this, the outputs I tested were very convincing!
+
+## Training data
+
+The data was 29222 MtG card flavour texts. The model was based on the "gpt2" pretrained transformer: https://huggingface.co/gpt2.
+
+## Training procedure
+
+Only English language MtG flavour texts were scraped from the [Scryfall](https://scryfall.com/) API. Empty strings and any non-UTF-8 encoded tokens were removed leaving 29222 entries.
+This was trained using google Colab with a T4 instance. 4 epochs, adamW optimizer with default parameters and a batch size of 32. Token embedding lengths were capped at 98 tokens as this was the longest string and an attention mask was added to the training model to ignore all padding tokens.
+
+## Eval results
+
+Average Training Loss: 0.44866578806635815.
+Validation loss: 0.5606984243444775.
+
+Sample model outputs:
+
+1. "Every branch a crossroads, every vine a swift steed."
+	—Gwendlyn Di Corci
+
+2. "The secrets of this world will tell their masters where to strike if need be."
+	—Noyan Dar, Tazeem roilmage
+
+3. "The secrets of nature are expensive. You'd be better off just to have more freedom."
+
+4. "Even the Dwarves knew to leave some stones unturned."
+
+5. "The wise always keep an ear open to the whispers of power."

+## Intended uses & limitations
+
+Make sure to preprocess your data using [these methods](https://github.com/microsoft/GLUECoS/blob/master/Data/Preprocess_Scripts/preprocess_sent_en_es.py) before using this model.
+
+#### How to use
+
+Here is how to use this model to get the features of a given text in *PyTorch*:
+
+```python
+# You can include sample code which will be formatted
+from transformers import BertTokenizer, BertModelForSequenceClassification
+tokenizer = AutoTokenizer.from_pretrained('rohanrajpal/bert-base-en-es-codemix-cased')
+model = AutoModelForSequenceClassification.from_pretrained('rohanrajpal/bert-base-en-es-codemix-cased')
+text = "Replace me by any text you'd like."
+encoded_input = tokenizer(text, return_tensors='pt')
+output = model(**encoded_input)
+```
+
+and in *TensorFlow*:

+```python
+from transformers import BertTokenizer, TFBertModel
+tokenizer = BertTokenizer.from_pretrained('rohanrajpal/bert-base-en-es-codemix-cased')
+model = TFBertModel.from_pretrained('rohanrajpal/bert-base-en-es-codemix-cased')
+text = "Replace me by any text you'd like."
+encoded_input = tokenizer(text, return_tensors='tf')
+output = model(encoded_input)
+```
+
+#### Limitations and bias
+
+Since I dont know spanish, I cant verify the quality of annotations or the dataset itself. This is a very simple transfer learning approach and I'm open to discussions to improve upon this.

+# Bangla BERT Base
+A long way passed. Here is our **Bangla-Bert**! It is now available in huggingface model hub. 
+
+[Bangla-Bert-Base](https://github.com/sagorbrur/bangla-bert) is a pretrained language model of Bengali language using mask language modeling described in [BERT](https://arxiv.org/abs/1810.04805) and it's github [repository](https://github.com/google-research/bert)
+
+
+
+## Pretrain Corpus Details
+Corpus was downloaded from two main sources:
+
+* Bengali commoncrawl copurs downloaded from [OSCAR](https://oscar-corpus.com/)
+* [Bengali Wikipedia Dump Dataset](https://dumps.wikimedia.org/bnwiki/latest/)
+
+After downloading these corpus, we preprocessed it as a Bert format. which is one sentence per line and an extra newline for new documents. 
+
+```
+sentence 1
+sentence 2
+
+sentence 1
+sentence 2
+
+```
+
+## Building Vocab
+We used [BNLP](https://github.com/sagorbrur/bnlp) package for training bengali sentencepiece model with vocab size 102025. We preprocess the output vocab file as Bert format.
+Our final vocab file availabe at [https://github.com/sagorbrur/bangla-bert](https://github.com/sagorbrur/bangla-bert) and also at [huggingface](https://huggingface.co/sagorsarker/bangla-bert-base) model hub.
+
+## Training Details
+* Bangla-Bert was trained with code provided in Google BERT's github repository (https://github.com/google-research/bert)
+* Currently released model follows bert-base-uncased model architecture (12-layer, 768-hidden, 12-heads, 110M parameters)
+* Total Training Steps: 1 Million
+* The model was trained on a single Google Cloud TPU

+## How to Use
+You can use this model directly with a pipeline for masked language modeling:
+
+```py
+from transformers import BertForMaskedLM, BertTokenizer, pipeline
+
+model = BertForMaskedLM.from_pretrained("bangla-bert-base")
+tokenizer = BertTokenizer.from_pretrained("bangla-bert-base")
+nlp = pipeline('fill-mask', model=model, tokenizer=tokenizer)
+for pred in nlp(f"আমি বাংলায় {nlp.tokenizer.mask_token} গাই।"):
+  print(pred)
+
+# {'sequence': '[CLS] আমি বাংলায গান গাই । [SEP]', 'score': 0.13404667377471924, 'token': 2552, 'token_str': 'গান'}

+# astroGPT 🪐
+
+## Model description
+
+This is a GPT-2 model fine-tuned on Western zodiac signs. For more information about GPT-2, take a look at 🤗 Hugging Face's GPT-2 [model card](https://huggingface.co/gpt2). You can use astroGPT to generate a daily horoscope by entering the current date.
+
+## How to use
+
+To use this model, simply enter the current date like so `Mon DD, YEAR`:
+
+```python
+from transformers import AutoTokenizer, AutoModelWithLMHead
+
+tokenizer = AutoTokenizer.from_pretrained("stevhliu/astroGPT")
+model = AutoModelWithLMHead.from_pretrained("stevhliu/astroGPT")
+
+input_ids = tokenizer.encode('Sep 03, 2020', return_tensors='pt').to('cuda')
+
+sample_output = model.generate(input_ids,
+                               do_sample=True, 
+                               max_length=75,
+                               top_k=20, 
+                               top_p=0.97)
+                                
+print(sample_output)
+```
+
+## Limitations and bias
+
+astroGPT inherits the same biases that affect GPT-2 as a result of training on a lot of non-neutral content on the internet. The model does not currently support zodiac sign-specific generation and only returns a general horoscope. While the generated text may occasionally mention a specific zodiac sign, this is  due to how the horoscopes were originally written by it's human authors.
+
+## Data
+
+The data was scraped from [Horoscope.com](https://www.horoscope.com/us/index.aspx) and trained on 4.7MB of text. The text was collected from four categories (daily, love, wellness, career) and span from 09/01/19 to 08/01/2020. The archives only store horoscopes dating a year back from the current date.
+
+## Training and results
+
+The text was tokenized using the fast GPT-2 BPE [tokenizer](https://huggingface.co/transformers/model_doc/gpt2.html#gpt2tokenizerfast). It has a vocabulary size of 50,257 and sequence length of 1024 tokens. The model was trained with on one of Google Colaboratory's GPU's for approximately 2.5 hrs with [fastai's](https://docs.fast.ai/) learning rate finder, discriminative learning rates and 1cycle policy. See table below for a quick summary of the training procedure and results.

+# LXMERT
+
+## Model Description
+
+[LXMERT](https://arxiv.org/abs/1908.07490) is a pre-trained multimodal transformer. The model takes an image and a sentence as input and compute cross-modal representions. The model is converted from [LXMERT github](https://github.com/airsplay/lxmert) by [Antonio Mendoza](https://avmendoza.info/) and is authored by [Hao Tan](https://www.cs.unc.edu/~airsplay/).
+
+![](./lxmert_model-1.jpg?raw=True)
+
+## Usage
+
+
+## Training Data and Prodcedure
+The model is jointly trained on multiple vision-and-language datasets.
+We included two image captioning datsets (i.e., [MS COCO](http://cocodataset.org/#home), [Visual Genome](https://visualgenome.org/)) and three image-question answering datasets (i.e.,  [VQA](https://visualqa.org/), [GQA](https://cs.stanford.edu/people/dorarad/gqa/), [VG QA](https://github.com/yukezhu/visual7w-toolkit)). The model is pre-trained on the above datasets  for 20 epochs (roughly 670K iterations with batch size 256), which takes around 8 days on 4 Titan V cards. The details of training could be found in the [LXMERT paper](https://arxiv.org/pdf/1908.07490.pdf).
