+# CamemBERT: a Tasty French Language Model
+
+## Introduction
+
+[CamemBERT](https://arxiv.org/abs/1911.03894) is a state-of-the-art language model for French based on the RoBERTa model. 
+
+It is now available on Hugging Face in 6 different versions with varying number of parameters, amount of pretraining data and pretraining data source domains. 
+
+For further information or requests, please go to [Camembert Website](https://camembert-model.fr/)

+## How to use CamemBERT with HuggingFace
+
+##### Load CamemBERT and its sub-word tokenizer :
+```python
+from transformers import CamembertModel, CamembertTokenizer
+
+# You can replace "camembert-base" with any other model from the table, e.g. "camembert/camembert-large".
+tokenizer = CamembertTokenizer.from_pretrained("camembert/camembert-base-ccnet-4gb")
+camembert = CamembertModel.from_pretrained("camembert/camembert-base-ccnet-4gb")
+
+camembert.eval()  # disable dropout (or leave in train mode to finetune)
+
+```
+
+##### Filling masks using pipeline 
+```python
+from transformers import pipeline 
+
+camembert_fill_mask  = pipeline("fill-mask", model="camembert/camembert-base-ccnet-4gb", tokenizer="camembert/camembert-base-ccnet-4gb")
+results = camembert_fill_mask("Le camembert est-il  <mask> ?")
+# results
+#[{'sequence': '<s> Le camembert est-il sain?</s>', 'score': 0.07001790404319763, 'token': 10286}, 
+#{'sequence': '<s> Le camembert est-il français?</s>', 'score': 0.057594332844018936, 'token': 384}, 
+#{'sequence': '<s> Le camembert est-il bon?</s>', 'score': 0.04098724573850632, 'token': 305}, 
+#{'sequence': '<s> Le camembert est-il périmé?</s>', 'score': 0.03486393392086029, 'token': 30862}, 
+#{'sequence': '<s> Le camembert est-il cher?</s>', 'score': 0.021535946056246758, 'token': 1604}]
+
+```
+
+##### Extract contextual embedding features from Camembert output 
+```python
+import torch
+# Tokenize in sub-words with SentencePiece
+tokenized_sentence = tokenizer.tokenize("J'aime le camembert !")
+# ['▁J', "'", 'aime', '▁le', '▁ca', 'member', 't', '▁!'] 
+
+# 1-hot encode and add special starting and end tokens 
+encoded_sentence = tokenizer.encode(tokenized_sentence)
+# [5, 133, 22, 1250, 16, 12034, 14324, 81, 76, 6]
+# NB: Can be done in one step : tokenize.encode("J'aime le camembert !")
+
+# Feed tokens to Camembert as a torch tensor (batch dim 1)
+encoded_sentence = torch.tensor(encoded_sentence).unsqueeze(0)
+embeddings, _ = camembert(encoded_sentence)
+# embeddings.detach()
+# embeddings.size torch.Size([1, 10, 768])
+#tensor([[[ 0.0331,  0.0095, -0.2776,  ...,  0.2875, -0.0827, -0.2467],
+#         [-0.1348,  0.0478, -0.5409,  ...,  0.8330,  0.0467,  0.0662],
+#         [ 0.0920, -0.0264,  0.0177,  ...,  0.1112,  0.0108, -0.1123],
+#         ...,
+```
+
+##### Extract contextual embedding features from all Camembert layers
+```python
+from transformers import CamembertConfig
+# (Need to reload the model with new config)
+config = CamembertConfig.from_pretrained("camembert/camembert-base-ccnet-4gb", output_hidden_states=True)
+camembert = CamembertModel.from_pretrained("camembert/camembert-base-ccnet-4gb", config=config)
+
+embeddings, _, all_layer_embeddings = camembert(encoded_sentence)
+#  all_layer_embeddings list of len(all_layer_embeddings) == 13 (input embedding layer + 12 self attention layers)
+all_layer_embeddings[5]
+# layer 5 contextual embedding : size torch.Size([1, 10, 768])
+#tensor([[[-0.0144,  0.1855,  0.4895,  ..., -0.1537,  0.0107, -0.2293],
+#         [-0.6664, -0.0880, -0.1539,  ...,  0.3635,  0.4047,  0.1258],
+#         [ 0.0511,  0.0540,  0.2545,  ...,  0.0709, -0.0288, -0.0779],
+#         ...,
+```
