+TAPAS
+-----------------------------------------------------------------------------------------------------------------------
+
+Overview
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The TAPAS model was proposed in `TAPAS: Weakly Supervised Table Parsing via Pre-training
+<https://www.aclweb.org/anthology/2020.acl-main.398>`__ by Jonathan Herzig, Paweł Krzysztof Nowak, Thomas Müller, Francesco 
+Piccinno and Julian Martin Eisenschlos. It's a BERT-based model specifically designed (and pre-trained) for answering questions
+about tabular data. Compared to BERT, TAPAS uses relative position embeddings and has 7 token types that encode tabular
+structure. TAPAS is pre-trained on the masked language modeling (MLM) objective on a large dataset comprising millions
+of tables from English Wikipedia and corresponding texts. For question answering, TAPAS has 2 heads on top: a cell
+selection head and an aggregation head, for (optionally) performing aggregations (such as counting or summing) among
+selected cells. TAPAS has been fine-tuned on several datasets: SQA (Sequential Question Answering by Microsoft), WTQ
+(Wiki Table Questions by Stanford University) and WikiSQL (by Salesforce). It achieves state-of-the-art on both SQA and
+WTQ, while having comparable performance to SOTA on WikiSQL, with a much simpler architecture.
+
+The abstract from the paper is the following:
+
+*Answering natural language questions over tables is usually seen as a semantic parsing task. To alleviate the
+collection cost of full logical forms, one popular approach focuses on weak supervision consisting of denotations
+instead of logical forms. However, training semantic parsers from weak supervision poses difficulties, and in addition,
+the generated logical forms are only used as an intermediate step prior to retrieving the denotation. In this paper, we
+present TAPAS, an approach to question answering over tables without generating logical forms. TAPAS trains from weak
+supervision, and predicts the denotation by selecting table cells and optionally applying a corresponding aggregation
+operator to such selection. TAPAS extends BERT's architecture to encode tables as input, initializes from an effective
+joint pre-training of text segments and tables crawled from Wikipedia, and is trained end-to-end. We experiment with
+three different semantic parsing datasets, and find that TAPAS outperforms or rivals semantic parsing models by
+improving state-of-the-art accuracy on SQA from 55.1 to 67.2 and performing on par with the state-of-the-art on WIKISQL
+and WIKITQ, but with a simpler model architecture. We additionally find that transfer learning, which is trivial in our
+setting, from WIKISQL to WIKITQ, yields 48.7 accuracy, 4.2 points above the state-of-the-art.*
+
+In addition, the authors have further pre-trained TAPAS to recognize table entailment, by creating a balanced dataset
+of millions of automatically created training examples which are learned in an intermediate step prior to fine-tuning.
+The authors of TAPAS call this further pre-training intermediate pre-training (since TAPAS is first pre-trained on MLM,
+and then on another dataset). They found that intermediate pre-training further improves performance on SQA, achieving
+a new state-of-the-art as well as state-of-the-art on TabFact, a large-scale dataset with 16k Wikipedia tables for
+table entailment (a binary classification task). For more details, see their follow-up paper: `Understanding tables with
+intermediate pre-training <https://arxiv.org/abs/2010.00571>`__ by Julian Martin Eisenschlos, Syrine Krichene and
+Thomas Müller.
+
+The original code can be found `here <https://github.com/google-research/tapas>`__. This page also includes links to the 
+datasets (SQA, WTQ, WikiSQL and TabFact).
+
+Tips:
+
+- TAPAS is a model that uses relative position embeddings by default (restarting the position embeddings at every cell
+  of the table). Note that this is something that was added after the publication of the original TAPAS paper. According 
+  to the authors, this usually results in a slightly better performance, and allows you to encode longer sequences without 
+  running out of embeddings. This is reflected in the ``reset_position_index_per_cell`` parameter of :class:`~transformers.TapasConfig`, 
+  which is set to ``True`` by default. 
+  The latest versions of the models available in the `model hub <https://huggingface.co/models?search=tapas>`_ all use relative 
+  position embeddings. You can still use the ones with absolute position embeddings by passing in a certain version when calling the
+  `.from_pretrained` method as explained in the model cards. 
+  Note that it's usually advised to pad the inputs on the right rather than the left.
+- TAPAS is based on BERT, so ``TAPAS-base`` for example corresponds to a ``BERT-base`` architecture. Of course, TAPAS-large 
+  will result in the best performance (the results reported in the paper are from TAPAS-large). Metrics of the various 
+  sized models are shown on the `original Github repository <https://github.com/google-research/tapas>`_. 
+- TAPAS has checkpoints fine-tuned on SQA, which are capable of answering questions related to a table in a
+  conversational set-up. This means that you can ask follow-up questions such as "what is his age?" related to the
+  previous question. Note that the forward pass of TAPAS is a bit different in case of a conversational set-up: in that
+  case, you have to feed every training example one by one to the model, such that the `prev_label_ids` token type ids
+  can be overwritten by the predicted `label_ids` of the model to the previous question. See "Usage" section for more info.
+- TAPAS is similar to BERT and therefore relies on the masked language modeling (MLM) objective. It is therefore
+  efficient at predicting masked tokens and at NLU in general, but is not optimal for text generation. Models trained
+  with a causal language modeling (CLM) objective are better in that regard.
+
+
+Usage: fine-tuning
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Here we explain how you can fine-tune :class:`~transformers.TapasForQuestionAnswering` on your own dataset. 
+
+===========================================================================
+STEP 1: Choose one of the 3 ways in which you can use TAPAS - or experiment
+===========================================================================
+
+Basically, there are 3 different ways in which one can fine-tune :class:`~transformers.TapasForQuestionAnswering`, corresponding to 
+the different datasets on which Tapas was fine-tuned:
+
+1. SQA: if you're interested in asking follow-up questions related to a table, in a conversational set-up. For example if you 
+   first ask "what's the name of the first actor?" then you can ask a follow-up question such as "how old is he?". Here, questions 
+   do not involve any aggregation (all questions are cell selection questions).
+2. WTQ: if you're not interested in asking questions in a conversational set-up, but rather just asking questions related 
+   to a table, which might involve aggregation, such as counting a number of rows, summing up cell values or averaging cell values. 
+   You can then for example ask "what's the total number of goals Cristiano Ronaldo made in his career?". This case is also called **weak 
+   supervision**, since the model itself must learn the appropriate aggregation operator (SUM/COUNT/AVERAGE/NONE) given only the answer 
+   to the question as supervision.
+3. WikiSQL-supervised: this dataset is based on WikiSQL with the model being given the ground truth aggregation operator during training. 
+   This is also called **strong supervision**. Here, learning the appropriate aggregation operator is much easier.
+
+To summarize:
+
+------------------------------------+----------------------+-------------------------------------------------------------------------------------------------------------------+
+| **Task**                           | **Example datasets** | **Description**                                                                                                   |
+------------------------------------+----------------------+-------------------------------------------------------------------------------------------------------------------+
+| Conversational                     | SQA                  | Conversational, only cell selection questions                                                                     |
+------------------------------------+----------------------+-------------------------------------------------------------------------------------------------------------------+
+| Weak supervision for aggregation   | WTQ                  | Questions might involve aggregation, and the model must learn this given only the answer as supervision           |
+------------------------------------+----------------------+-------------------------------------------------------------------------------------------------------------------+
+| Strong supervision for aggregation | WikiSQL-supervised   | Questions might involve aggregation, and the model must learn this given the gold aggregation operator            |
+------------------------------------+----------------------+-------------------------------------------------------------------------------------------------------------------+
+
+Initializing a model with a pre-trained base and randomly initialized classification heads from the model hub is as easy as:
+
+.. code-block::
+
+        >>> from transformers import TapasForQuestionAnswering
+
+        >>> # for example, the base sized model 
+        >>> model = TapasForQuestionAnswering.from_pretrained('google/tapas-base-uncased')
+
+
+Of course, you don't necessarily have to follow one of these three ways in which TAPAS was fine-tuned. You can also experiment by defining any hyperparameters 
+you want when initializing :class:`~transformers.TapasConfig`, and then create a :class:`~transformers.TapasForQuestionAnswering` based on that 
+configuration. For example, if you have a dataset that has both conversational questions and questions that might involve aggregation, then you can do it 
+this way. Here's an example:
+
+.. code-block::
+
+        >>> from transformers import TapasConfig, TapasForQuestionAnswering
+
+        >>> # you can initialize the classification heads any way you want (see docs of TapasConfig)
+        >>> config = TapasConfig(num_aggregation_labels=3, average_logits_per_cell=True, select_one_column=False)
+        >>> # initializing the pre-trained base sized model with our custom classification heads
+        >>> model = TapasForQuestionAnswering.from_pretrained('google/tapas-base-uncased', config=config)
+
+What you can also do is start from an already fine-tuned checkpoint. A note here is that the already fine-tuned checkpoint on WTQ has some issues
+due to the L2-loss which is somewhat brittle. See `here <https://github.com/google-research/tapas/issues/91#issuecomment-735719340>`__ for more info.
+
+For a list of all pre-trained and fine-tuned TAPAS checkpoints available in the HuggingFace model hub, see `here <https://huggingface.co/models?search=tapas>`__.
+
+===========================================
+STEP 2: Prepare your data in the SQA format
+===========================================
+
+Second, no matter what you picked above, you should prepare your dataset in the `SQA format <https://www.microsoft.com/en-us/download/details.aspx?id=54253>`__. 
+This format is a TSV/CSV file with the following columns:
+
+- ``id``: optional, id of the table-question pair, for bookkeeping purposes. 
+- ``annotator``: optional, id of the person who annotated the table-question pair, for bookkeeping purposes. 
+- ``position``: integer indicating if the question is the first, second, third,... related to the table. Only required in case of conversational setup (SQA). 
+  You don't need this column in case you're going for WTQ/WikiSQL-supervised.
+- ``question``: string
+- ``table_file``: string, name of a csv file containing the tabular data
+- ``answer_coordinates``: list of one or more tuples (each tuple being a cell coordinate, i.e. row, column pair that is part of the answer)
+- ``answer_text``: list of one or more strings (each string being a cell value that is part of the answer)
+- ``aggregation_label``: index of the aggregation operator. Only required in case of strong supervision for aggregation (the WikiSQL-supervised case)
+- ``float_answer``: the float answer to the question, if there is one (np.nan if there isn't). Only required in case of weak supervision for aggregation (such as WTQ and WikiSQL)
+
+The tables themselves should be present in a folder, each table being a separate csv file. Note that the authors of the TAPAS algorithm used conversion 
+scripts with some automated logic to convert the other datasets (WTQ, WikiSQL) into the SQA format. The author explains this `here <https://github.com/google-research/tapas/issues/50#issuecomment-705465960>`__. 
+Interestingly, these conversion scripts are not perfect (the ``answer_coordinates`` and ``float_answer`` fields are populated based on the ``answer_text``), 
+meaning that WTQ and WikiSQL results could actually be improved.
+
+
+==========================================================================================
+STEP 3: Convert your data into PyTorch tensors using :class:`~transformers.TapasTokenizer`
+==========================================================================================
+
+Third, given that you've prepared your data in this TSV/CSV format (and corresponding CSV files containing the tabular data), you can then 
+use :class:`~transformers.TapasTokenizer` to convert table-question pairs into :obj:`input_ids`, :obj:`attention_mask`, :obj:`token_type_ids`
+and so on. Again, based on which of the three cases you picked above, :class:`~transformers.TapasForQuestionAnswering` requires different inputs 
+to be fine-tuned:
+
+------------------------------------+----------------------------------------------------------------------------------------------+
+| **Task**                           | **Required inputs**                                                                          |
+------------------------------------+----------------------------------------------------------------------------------------------+
+| Conversational                     | ``input_ids``, ``attention_mask``, ``token_type_ids``, ``label_ids``                         |
+------------------------------------+----------------------------------------------------------------------------------------------+
+| Weak supervision for aggregation   | ``input_ids``, ``attention_mask``, ``token_type_ids``, ``label_ids``, ``numeric_values``,    |
+|                                    | ``numeric_values_scale``, ``float_answer``                                                   |
+------------------------------------+----------------------------------------------------------------------------------------------+
+| Strong supervision for aggregation | ``input ids``, ``attention mask``, ``token type ids``, ``label ids``, ``aggregation_labels`` |
+------------------------------------+----------------------------------------------------------------------------------------------+
+
+:class:`~transformers.TapasTokenizer` creates the ``label_ids``, ``numeric_values`` and ``numeric_values_scale`` based on the 
+``answer_coordinates`` and ``answer_text`` columns of the TSV file. The ``float_answer`` and ``aggregation_labels`` are already in the TSV file of step 2. 
+Here's an example:
+
+.. code-block::
+
+        >>> from transformers import TapasTokenizer
+        >>> import pandas as pd
+
+        >>> model_name = 'google/tapas-base-uncased'
+        >>> tokenizer = TapasTokenizer.from_pretrained(model_name)
+
+        >>> data = {'Actors': ["Brad Pitt", "Leonardo Di Caprio", "George Clooney"], 'Number of movies': ["87", "53", "69"]}
+        >>> queries = ["What is the name of the first actor?", "How many movies has George Clooney played in?", "What is the total number of movies?"]
+        >>> answer_coordinates = [[(0, 0)], [(1, 0)], [(0, 2), (1, 2), (2, 2)]]
+        >>> answer_text = [["Brad Pitt"], ["69"], ["209"]]
+        >>> table = pd.Dataframe(data)
+        >>> inputs = tokenizer(table=table, queries=queries, answer_coordinates=answer_coordinates, answer_text=answer_text, padding='max_length', return_tensors='pt')
+        >>> inputs
+        {'input_ids': tensor([[ ... ]]), 'attention_mask': tensor([[...]]), 'token_type_ids': tensor([[[...]]]),
+        'numeric_values': tensor([[ ... ]]), 'numeric_values_scale: tensor([[ ... ]]), label_ids: tensor([[ ... ]])}
+
+Note that :class:`~transformers.TapasTokenizer` expects the data of the table to be text-only. You can use ``.astype(str)`` on a dataframe to turn it into
+text-only data. Of course, this only shows how to encode a single training example. It is advised to create a PyTorch dataset and a corresponding dataloader:
+
+.. code-block::
+
+        >>> import torch
+        >>> import pandas as pd
+
+        >>> tsv_path = "your_path_to_the_tsv_file"
+        >>> table_csv_path = "your_path_to_a_directory_containing_all_csv_files"
+
+        >>> class TableDataset(torch.utils.data.Dataset):
+        ...     def __init__(self, data, tokenizer):
+        ...         self.data = data
+        ...         self.tokenizer = tokenizer
+        ...
+        ...     def __getitem__(self, idx):
+        ...         item = data.iloc[idx]
+        ...         table = pd.read_csv(table_csv_path + item.table_file).astype(str)
+        ...         encoding = self.tokenizer(table=table, 
+        ...                                 queries=item.question, 
+        ...                                 answer_coordinates=item.answer_coordinates, 
+        ...                                 answer_text=item.answer_text,
+        ...                                 padding="max_length",
+        ...                                 return_tensors="pt"
+        ...         )
+        ...         # we add the float_answer which is also required (weak supervision for aggregation)
+        ...         encoding["float_answer"] = torch.tensor(item.float_answer) 
+        ...         return encoding
+        ...
+        ...     def __len__(self):
+        ...        return len(self.data)
+
+        >>> data = pd.read_csv(tsv_path, sep='\t')
+        >>> train_dataset = TableDataset(data, tokenizer)
+        >>> train_dataloader = torch.utils.data.DataLoader(train_dataset, batch_size=32)
+
+Note that here, we encode each table-question pair independently. This is fine as long as your dataset is **not conversational**. In case your 
+dataset involves conversational questions (such as in SQA), then you should first group together the ``queries``, ``answer_coordinates`` and 
+``answer_text`` per table (in the order of their ``position`` index) and batch encode each table with its questions. This will make sure that 
+the ``prev_label_ids`` token types (see docs of :class:`~transformers.TapasTokenizer`) are set correctly. 
+
+===================================================
+STEP 4: Train (fine-tune) TapasForQuestionAnswering
+===================================================
+
+You can then fine-tune :class:`~transformers.TapasForQuestionAnswering` using native PyTorch as follows:
+
+.. code-block::
+
+        >>> from transformers import TapasForQuestionAnswering
+
+        >>> model = TapasForQuestionAnswering.from_pretrained("google/tapas-base-uncased")
+
+        >>> for epoch in range(2):  # loop over the dataset multiple times
+        ...    for idx, batch in enumerate(train_dataloader):
+        ...         # get the inputs; 
+        ...         input_ids, attention_mask, token_type_ids, label_ids, numeric_values, numeric_values_scale, float_answer = batch
+
+        ...         # zero the parameter gradients
+        ...         optimizer.zero_grad()
+
+        ...         # forward + backward + optimize
+        ...         outputs = model(input_ids=input_ids, attention_mask=attention_mask, token_type_ids=token_type_ids, 
+        ...                        label_ids=label_ids, numeric_values=numeric_values, numeric_values_scale=numeric_values_scale, 
+        ...                        float_answer=float_answer)
+        ...         loss = outputs.loss
+        ...         loss.backward()
+        ...         optimizer.step()
+
+Usage: inference
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Here we explain how you can use :class:`~transformers.TapasForQuestionAnswering` for inference (i.e. making predictions on new data).
+For inference, only ``input_ids``, ``attention_mask`` and ``token_type_ids`` (which you can obtain using 
+:class:`~transformers.TapasTokenizer`) have to be provided to the model to obtain the logits. Next, you can use the handy 
+``convert_logits_to_predictions`` method of :class:`~transformers.TapasTokenizer` to convert these into predicted coordinates 
+and optional aggregation indices. 
+
+However, note that inference is **different** depending on whether or not the setup is conversational. In a non-conversational set-up, inference 
+can be done in parallel on all table-question pairs of a batch. Here's an example of that:
+
+.. code-block::
+
+        >>> from transformers import TapasTokenizer, TapasForQuestionAnswering
+        >>> import pandas as pd 
+
+        >>> model_name = 'google/tapas-base-uncased-finetuned-wtq'
+        >>> model = TapasForQuestionAnswering.from_pretrained(model_name)
+        >>> tokenizer = TapasTokenizer.from_pretrained(model_name)
+
+        >>> data = {'Actors': ["Brad Pitt", "Leonardo Di Caprio", "George Clooney"], 'Number of movies': ["87", "53", "69"]}
+        >>> queries = ["What is the name of the first actor?", "How many movies has George Clooney played in?", "What is the total number of movies?"]
+        >>> table = pd.Dataframe(data)
+        >>> inputs = tokenizer(table=table, queries=queries, padding='max_length', return_tensors="pt") 
+        >>> outputs = model(**inputs)
+        >>> predicted_answer_coordinates, predicted_aggregation_indices = tokenizer.convert_logits_to_predictions(
+        ...         inputs, 
+        ...         output.logits, 
+        ...         outputs.logits_aggregation
+        ...)
+
+        >>> # let's print out the results:
+        >>> id2aggregation = {0: "NONE", 1: "SUM", 2: "AVERAGE", 3:"COUNT"}
+        >>> aggregation_predictions_string = [id2aggregation[x] for x in predicted_aggregation_indices]
+
+        >>> answers = []
+        >>> for coordinates in predicted_answer_coordinates:
+        ...   if len(coordinates) == 1:
+        ...     # only a single cell:
+        ...     answers.append(df.iat[coordinates[0]])
+        ...   else:
+        ...     # multiple cells

+- native AMP (`--fp16` and no apex) may lead to a huge memory leak and require 10x gpu memory. This has been fixed in pytorch-nightly and the minimal official version to have this fix will be pytorch-1.8. Until then if you have to use mixed precision please use AMP only with pytorch-nightly or NVIDIA's apex. Reference: https://github.com/huggingface/transformers/issues/8403

+# TAPAS base model 
+
+This model corresponds to the `tapas_inter_masklm_base_reset` checkpoint of the [original Github repository](https://github.com/google-research/tapas). 
+
+Disclaimer: The team releasing TAPAS did not write a model card for this model so this model card has been written by
+the Hugging Face team and contributors.
+
+## Model description
+
+TAPAS is a BERT-like transformers model pretrained on a large corpus of English data from Wikipedia in a self-supervised fashion. 
+This means it was pretrained on the raw tables and associated texts 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 texts. More precisely, it
+was pretrained with two objectives:
+
+- Masked language modeling (MLM): taking a (flattened) table and associated context, the model randomly masks 15% of the words in 
+  the input, then runs the entire (partially masked) sequence through the model. The model then has to predict the masked words. 
+  This is different from traditional recurrent neural networks (RNNs) that usually see the words one after the other, 
+  or from autoregressive models like GPT which internally mask the future tokens. It allows the model to learn a bidirectional 
+  representation of a table and associated text.
+- Intermediate pre-training: to encourage numerical reasoning on tables, the authors additionally pre-trained the model by creating 
+  a balanced dataset of millions of syntactically created training examples. Here, the model must predict (classify) whether a sentence 
+  is supported or refuted by the contents of a table. The training examples are created based on synthetic as well as counterfactual statements.
+
+This way, the model learns an inner representation of the English language used in tables and associated texts, which can then be used 
+to extract features useful for downstream tasks such as answering questions about a table, or determining whether a sentence is entailed
+or refuted by the contents of a table. Fine-tuning is done by adding classification heads on top of the pre-trained model, and then jointly
+train the randomly initialized classification heads with the base model on a labelled dataset. 
+
+## Intended uses & limitations
+
+You can use the raw model for masked language modeling, but it's mostly intended to be fine-tuned on a downstream task. 
+See the [model hub](https://huggingface.co/models?filter=tapas) to look for fine-tuned versions on a task that interests you.
+
+
+Here is how to use this model to get the features of a given table-text pair in PyTorch:
+
+```python
+from transformers import TapasTokenizer, TapasModel
+import pandas as pd
+tokenizer = TapasTokenizer.from_pretrained('tapase-base')
+model = TapasModel.from_pretrained("tapas-base")
+data = {'Actors': ["Brad Pitt", "Leonardo Di Caprio", "George Clooney"],
+         'Age': ["56", "45", "59"],
+         'Number of movies': ["87", "53", "69"]
+}
+table = pd.DataFrame.from_dict(data)
+queries = ["How many movies has George Clooney played in?"]
+text = "Replace me by any text you'd like."
+encoded_input = tokenizer(table=table, queries=queries, return_tensors='pt')
+output = model(**encoded_input)
+```
+
+## Training data
+
+For masked language modeling (MLM), a collection of 6.2 million tables was extracted from English Wikipedia: 3.3M of class [Infobox](https://en.wikipedia.org/wiki/Help:Infobox)
+and 2.9M of class WikiTable. The author only considered tables with at most 500 cells. As a proxy for questions that appear in the 
+downstream tasks, the authros extracted the table caption, article title, article description, segment title and text of the segment 
+the table occurs in as relevant text snippets. In this way, 21.3M snippets were created. For more info, see the original [TAPAS paper](https://www.aclweb.org/anthology/2020.acl-main.398.pdf).
+
+For intermediate pre-training, 2 tasks are introduced: one based on synthetic and the other from counterfactual statements. The first one 
+generates a sentence by sampling from a set of logical expressions that filter, combine and compare the information on the table, which is 
+required in table entailment (e.g., knowing that Gerald Ford is taller than the average president requires summing
+all presidents and dividing by the number of presidents). The second one corrupts sentences about tables appearing on Wikipedia by swapping 
+entities for plausible alternatives. Examples of the two tasks can be seen in Figure 1. The procedure is described in detail in section 3 of 
+the [TAPAS follow-up paper](https://www.aclweb.org/anthology/2020.findings-emnlp.27.pdf).
+
+## Training procedure
+
+### Preprocessing
+
+The texts are lowercased and tokenized using WordPiece and a vocabulary size of 30,000. The inputs of the model are
+then of the form:
+
+```
+[CLS] Context [SEP] Flattened table [SEP]
+```
+
+The details of the masking procedure for each sequence are the following:
+- 15% of the tokens are masked.
+- In 80% of the cases, the masked tokens are replaced by `[MASK]`.
+- In 10% of the cases, the masked tokens are replaced by a random token (different) from the one they replace.
+- In the 10% remaining cases, the masked tokens are left as is.
+
+The details of the creation of the synthetic and counterfactual examples can be found in the [follow-up paper](https://arxiv.org/abs/2010.00571). 
+
+### Pretraining
+
+The model was trained on 32 Cloud TPU v3 cores for one million steps with maximum sequence length 512 and batch size of 512.
+In this setup, pre-training takes around 3 days. The optimizer used is Adam with a learning rate of 5e-5, and a warmup ratio 
+of 0.10.
