-Callbacks
------------------------------------------------------------------------------------------------------------------------
-
-Callbacks are objects that can customize the behavior of the training loop in the PyTorch
-:class:`~transformers.Trainer` (this feature is not yet implemented in TensorFlow) that can inspect the training loop
-state (for progress reporting, logging on TensorBoard or other ML platforms...) and take decisions (like early
-stopping).
-
-Callbacks are "read only" pieces of code, apart from the :class:`~transformers.TrainerControl` object they return, they
-cannot change anything in the training loop. For customizations that require changes in the training loop, you should
-subclass :class:`~transformers.Trainer` and override the methods you need (see :doc:`trainer` for examples).
-
-By default a :class:`~transformers.Trainer` will use the following callbacks:
-
-- :class:`~transformers.DefaultFlowCallback` which handles the default behavior for logging, saving and evaluation.
-- :class:`~transformers.PrinterCallback` or :class:`~transformers.ProrgressCallback` to display progress and print the
-  logs (the first one is used if you deactivate tqdm through the :class:`~transformers.TrainingArguments`, otherwise
-  it's the second one).
-- :class:`~transformers.integrations.TensorBoardCallback` if tensorboard is accessible (either through PyTorch >= 1.4
-  or tensorboardX).
-- :class:`~transformers.integrations.WandbCallback` if `wandb <https://www.wandb.com/>`__ is installed.
-- :class:`~transformers.integrations.CometCallback` if `comet_ml <https://www.comet.ml/site/>`__ is installed.
-
-The main class that implements callbacks is :class:`~transformers.TrainerCallback`. It gets the
-:class:`~transformers.TrainingArguments` used to instantiate the :class:`~transformers.Trainer`, can access that
-Trainer's internal state via :class:`~transformers.TrainerState`, and can take some actions on the training loop via
-:class:`~transformers.TrainerControl`.

-The Blender chatbot model was proposed in `Recipes for building an open-domain chatbot <https://arxiv.org/pdf/2004.13637.pdf>`__ Stephen Roller, Emily Dinan, Naman Goyal, Da Ju, Mary Williamson, Yinhan Liu, Jing Xu, Myle Ott, Kurt Shuster, Eric M. Smith, Y-Lan Boureau, Jason Weston on 30 Apr 2020.

-The abstract of the paper is the following:
-
-*Building open-domain chatbots is a challenging area for machine learning research. While prior work has shown that scaling neural models in the number of parameters and the size of the data they are trained on gives improved results, we show that other ingredients are important for a high-performing chatbot. Good conversation requires a number of skills that an expert conversationalist blends in a seamless way: providing engaging talking points and listening to their partners, and displaying knowledge, empathy and personality appropriately, while maintaining a consistent persona. We show that large scale models can learn these skills when given appropriate training data and choice of generation strategy. We build variants of these recipes with 90M, 2.7B and 9.4B parameter models, and make our models and code publicly available. Human evaluations show our best models are superior to existing approaches in multi-turn dialogue in terms of engagingness and humanness measurements. We then discuss the limitations of this work by analyzing failure cases of our models.*

-Implementation Notes
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-- Blenderbot uses a standard `seq2seq model transformer <https://arxiv.org/pdf/1706.03762.pdf>`__ based architecture.
-- It inherits completely from :class:`~transformers.BartForConditionalGeneration`
-- Even though blenderbot is one model, it uses two tokenizers :class:`~transformers.BlenderbotSmallTokenizer` for 90M checkpoint and :class:`~transformers.BlenderbotTokenizer` for all other checkpoints.
-- :class:`~transformers.BlenderbotSmallTokenizer` will always return :class:`~transformers.BlenderbotSmallTokenizer`, regardless of checkpoint. To use the 3B parameter checkpoint, you must call :class:`~transformers.BlenderbotTokenizer` directly.
-- Available checkpoints can be found in the `model hub <https://huggingface.co/models?search=blenderbot>`__.

 ### Fine-tuning using Seq2SeqTrainer
 To use `Seq2SeqTrainer` for fine-tuning you should use the `finetune_trainer.py` script. It subclasses `Trainer` to extend it for seq2seq training. Except the `Trainer` releated `TrainingArguments`, it shares the same argument names as that of `finetune.py` file. One notable difference is that, calculating generative metrics (BLEU, ROUGE) is optional and is controlled using the `--predict_with_generate` argument, set this argument to calculate BLEU and ROUGE metrics.

-### Generating New Pseudolabels
-Here is the command I used to generate the pseudolabels in the second row of the table, after downloading XSUM from [here](https://cdn-datasets.huggingface.co/summarization/xsum.tar.gz). 
-
-```bash                                                                         
-python -m torch.distributed.launch --nproc_per_node=8 run_distributed_eval.py \
-    --model_name google/pegasus-xsum \ 
-    --save_dir pegasus_xsum \ 
-    --data_dir xsum \
-    --bs 8 --sync_timeout 60000 \
-    --max_source_length 512 \
-    --type_path train
-```
-
-+ These command takes a while to run. For example,  pegasus_cnn_cnn_pls.tgz took 8 hours on 8 GPUs.
-+ Pegasus does not work in fp16 :(, Bart, mBART and Marian do.
-+ Even if you have 1 GPU, `run_distributed_eval.py` is 10-20% faster than `run_eval.py` because it uses `SortishSampler` to minimize padding computation.

-# ProtT5-XL-BFD model
-
-Pretrained model on protein sequences using a masked language modeling (MLM) objective. It was introduced in
-[this paper](https://doi.org/10.1101/2020.07.12.199554) and first released in
-[this repository](https://github.com/agemagician/ProtTrans). This model is trained on uppercase amino acids: it only works with capital letter amino acids.
-
-
-## Model description
-
-ProtT5-XL-BFD is based on the `t5-3b` model and was pretrained on a large corpus of protein sequences in a self-supervised fashion.
-This means it was pretrained on the raw protein sequences only, with no humans labelling them in any way (which is why it can use lots of
-publicly available data) with an automatic process to generate inputs and labels from those protein sequences.
-
-One important difference between this T5 model and the original T5 version is the denosing objective.
-The original T5-3B model was pretrained using a span denosing objective, while this model was pre-trained with a Bart-like MLM denosing objective.
-The masking probability is consistent with the original T5 training by randomly masking 15% of the amino acids in the input.
-
-It has been shown that the features extracted from this self-supervised model (LM-embeddings) captured important biophysical properties governing protein shape.
-shape.
-This implied learning some of the grammar of the language of life realized in protein sequences.
-
-## Intended uses & limitations
-
-The model could be used for protein feature extraction or to be fine-tuned on downstream tasks.
-We have noticed in some tasks on can gain more accuracy by fine-tuning the model rather than using it as a feature extractor.
-We have also noticed that for feature extraction, its better to use the feature extracted from the encoder not from the decoder.
-
-### How to use
-
-Here is how to use this model to extract the features of a given protein sequence in PyTorch:
-
-```python
-from transformers import T5Tokenizer, T5Model
-import re
-import torch
-
-tokenizer = T5Tokenizer.from_pretrained('Rostlab/prot_t5_xl_bfd', do_lower_case=False)
-
-model = T5Model.from_pretrained("Rostlab/prot_t5_xl_bfd")
-
-sequences_Example = ["A E T C Z A O","S K T Z P"]
-
-sequences_Example = [re.sub(r"[UZOB]", "X", sequence) for sequence in sequences_Example]
-
-ids = tokenizer.batch_encode_plus(sequences_Example, add_special_tokens=True, padding=True)
-
-input_ids = torch.tensor(ids['input_ids'])
-attention_mask = torch.tensor(ids['attention_mask'])
-
-with torch.no_grad():
-    embedding = model(input_ids=input_ids,attention_mask=attention_mask,decoder_input_ids=None)
-
-# For feature extraction we recommend to use the encoder embedding
-encoder_embedding = embedding[2].cpu().numpy()
-decoder_embedding = embedding[0].cpu().numpy()
-```
-
-## Training data
-
-The ProtT5-XL-BFD model was pretrained on [BFD](https://bfd.mmseqs.com/), a dataset consisting of 2.1 billion protein sequences.
-
-## Training procedure
-
-### Preprocessing
-
-The protein sequences are uppercased and tokenized using a single space and a vocabulary size of 21. The rare amino acids "U,Z,O,B" were mapped to "X".
-The inputs of the model are then of the form:
-
-```
-Protein Sequence [EOS]
-```
-
-The preprocessing step was performed on the fly, by cutting and padding the protein sequences up to 512 tokens.
-
-The details of the masking procedure for each sequence are as follows:
-- 15% of the amino acids are masked.
-- In 90% of the cases, the masked amino acids are replaced by `[MASK]` token.
-- In 10% of the cases, the masked amino acids are replaced by a random amino acid (different) from the one they replace.
-
-### Pretraining
-
-The model was trained on a single TPU Pod V3-1024 for 1.2 million steps in total, using sequence length 512 (batch size 4k).
-It has a total of approximately 3B parameters and was trained using the encoder-decoder architecture.
-The optimizer used is AdaFactor with inverse square root learning rate schedule for pre-training.
-
-
-## Evaluation results
-
-When the model is used for feature etraction, this model achieves the following results:

-	abstract = {Computational biology and bioinformatics provide vast data gold-mines from protein sequences, ideal for Language Models (LMs) taken from Natural Language Processing (NLP). These LMs reach for new prediction frontiers at low inference costs. Here, we trained two auto-regressive language models (Transformer-XL, XLNet) and two auto-encoder models (Bert, Albert) on data from UniRef and BFD containing up to 393 billion amino acids (words) from 2.1 billion protein sequences (22- and 112 times the entire English Wikipedia). The LMs were trained on the Summit supercomputer at Oak Ridge National Laboratory (ORNL), using 936 nodes (total 5616 GPUs) and one TPU Pod (V3-512 or V3-1024). We validated the advantage of up-scaling LMs to larger models supported by bigger data by predicting secondary structure (3-states: Q3=76-84, 8 states: Q8=65-73), sub-cellular localization for 10 cellular compartments (Q10=74) and whether a protein is membrane-bound or water-soluble (Q2=89). Dimensionality reduction revealed that the LM-embeddings from unlabeled data (only protein sequences) captured important biophysical properties governing protein shape. This implied learning some of the grammar of the language of life realized in protein sequences. The successful up-scaling of protein LMs through HPC to larger data sets slightly reduced the gap between models trained on evolutionary information and LMs. Availability ProtTrans: \<a href="https://github.com/agemagician/ProtTrans"\>https://github.com/agemagician/ProtTrans\</a\>Competing Interest StatementThe authors have declared no competing interest.},

-
-## Usage Specifications
-
-
-For using this model, we have to first import AutoTokenizer and AutoModelWithLMHead Modules from transformers
-After that we have to specify, the pre-trained model,which in this case is 'abhilash1910/french-roberta' for the tokenizers and the model.
-
-
-```python
-from transformers import AutoTokenizer, AutoModelWithLMHead
-
-tokenizer = AutoTokenizer.from_pretrained("abhilash1910/french-roberta")
-
-model = AutoModelWithLMHead.from_pretrained("abhilash1910/french-roberta")
-```
-
-
-After this the model will be downloaded, it will take some time to download all the model files.
-For testing the model, we have to import  pipeline module from transformers and create a masked output model for inference as follows:
-
-
-```python
-from transformers import pipeline
-model_mask = pipeline('fill-mask', model='abhilash1910/french-roberta')
-model_mask("Le tweet <mask>.")
-```
-
-
-Some of the examples are also provided with generic French sentences:
-
-Example 1:
-
-
-```python
-model_mask("À ce jour, <mask> projet a entraîné")
-```
-
-
-Output:
-
-
-```bash
-[{'sequence': '<s>À ce jour, belles projet a entraîné</s>',
-  'score': 0.18685665726661682,

-# bert-base-5lang-cased
-This is a smaller version of [bert-base-multilingual-cased](https://huggingface.co/bert-base-multilingual-cased) that handles only 5 languages (en, fr, es, de and zh) instead of 104.
-The model is therefore 30% smaller than the original one (124M parameters instead of 178M) but gives exactly the same representations for the above cited languages. 
-Starting from `bert-base-5lang-cased` will facilitate the deployment of your model on public cloud platforms while keeping similar results. 
-For instance, Google Cloud Platform requires that the model size on disk should be lower than 500 MB for serveless deployments (Cloud Functions / Cloud ML) which is not the case of the original `bert-base-multilingual-cased`.
-
-For more information about the models size, memory footprint and loading time please refer to the table below:
-

-TinyBERT: Distilling BERT for Natural Language Understanding
-======== 
-TinyBERT is 7.5x smaller and 9.4x faster on inference than BERT-base and achieves competitive performances in the tasks of natural language understanding. It performs a novel transformer distillation at both the pre-training and task-specific learning stages. In general distillation, we use the original BERT-base without fine-tuning as the teacher and a large-scale text corpus as the learning data. By performing the Transformer distillation on the text from general domain, we obtain a general TinyBERT which provides a good initialization for the task-specific distillation. We here provide the general TinyBERT for your tasks at hand.

-### Overview
-
-This is a slightly smaller model trained on [OSCAR](https://oscar-corpus.com/) Sinhala dedup dataset. As Sinhala is one of those low resource languages, there are only a handful of models been trained. So, this would be a great place to start training for more downstream tasks. 
-
-## Model Specification
-
-
-The model chosen for training is [Roberta](https://arxiv.org/abs/1907.11692) with the following specifications:
- 1. vocab_size=52000
- 2. max_position_embeddings=514
- 3. num_attention_heads=12
- 4. num_hidden_layers=6
- 5. type_vocab_size=1
- 
-## How to Use
-You can use this model directly with a pipeline for masked language modeling:
-
-```py
-from transformers import AutoTokenizer, AutoModelWithLMHead, pipeline
-
-model = BertForMaskedLM.from_pretrained("keshan/SinhalaBERTo")
-tokenizer = BertTokenizer.from_pretrained("keshan/SinhalaBERTo")
-
-fill_mask = pipeline('fill-mask', model=model, tokenizer=tokenizer)
-
-fill_mask("මම ගෙදර <mask>.")
-

-LEGAL-BERT is a family of BERT models for the legal domain, intended to assist legal NLP research, computational law, and legal technology applications.  To pre-train the different variations of LEGAL-BERT, we collected 12 GB of diverse English legal text from several fields (e.g., legislation, court cases,  contracts) scraped from publicly available resources. Sub-domains variants (CONTRACTS-, EURLEX-, ECHR-) and/or general LEGAL-BERT perform better than using BERT out of the box for domain-specific tasks. A light-weight model (33% the size of BERT-BASE) pre-trained from scratch on legal data with competitive perfomance is also available.

-
----
-
-## Pre-training corpora
-
-The pre-training corpora of LEGAL-BERT include:
-
-* 116,062 documents of EU legislation, publicly available from EURLEX (http://eur-lex.europa.eu), the repository of EU Law running under the EU Publication Office.
-    
-* 61,826 documents of UK legislation, publicly available from the UK legislation portal (http://www.legislation.gov.uk).
-    
-* 19,867 cases from European Court of Justice (ECJ), also available from EURLEX.
-    
-* 12,554 cases from HUDOC, the repository of the European Court of Human Rights (ECHR) (http://hudoc.echr.coe.int/eng).
-    
-* 164,141 cases from various courts across the USA, hosted in the Case Law Access Project portal (https://case.law).
-    
-* 76,366 US contracts from EDGAR, the database of US Securities and Exchange Commission (SECOM) (https://www.sec.gov/edgar.shtml).
-
-## Pre-training details
-
-* We trained BERT using the official code provided in Google BERT's github repository (https://github.com/google-research/bert).
-* We released a model similar to the English BERT-BASE model (12-layer, 768-hidden, 12-heads, 110M parameters).
-* We chose to follow the same training set-up: 1 million training steps with batches of 256 sequences of length 512 with an initial learning rate 1e-4.
-* We were able to use a single Google Cloud TPU v3-8 provided for free from [TensorFlow Research Cloud (TFRC)](https://www.tensorflow.org/tfrc), while also utilizing [GCP research credits](https://edu.google.com/programs/credits/research). Huge thanks to both Google programs for supporting us!
-* Part of LEGAL-BERT is a light-weight model pre-trained from scratch on legal data, which achieves comparable performance to larger models, while being much more efficient (approximately 4 times faster) with a smaller environmental footprint.
