readme: # bengali-t5-base
  
  **bengali-t5-base** is a model trained on the Bengali portion of MT5 dataset. We used the `T5-base` model for this model.
  
  [Flax/Jax Community Week](https://discuss.huggingface.co/t/open-to-the-community-community-week-using-jax-flax-for-nlp-cv/7104), organized by [HuggingFace](https://huggingface.co/) and TPU usage sponsored by Google.
  
  The model is trained on around ~11B tokens (64 size batch, 512 tokens, 350k steps). 
  
  ## load tokenizer
  
  ```
  >>> tokenizer = transformers.AutoTokenizer.from_pretrained("flax-community/bengali-t5-base")
  >>> tokenizer.encode("আমি বাংলার গান গাই")
  >>> tokenizer.decode([93, 1912, 814, 5995, 3, 1])
  ```
  
  ```
  [93, 1912, 814, 5995, 3, 1]
  'আমি বাংলার গান গাই </s>'
  ```
  
  ## load model
  
  ```
  >>> config  = T5Config.from_pretrained("flax-community/bengali-t5-base")
  >>> model = FlaxT5ForConditionalGeneration.from_pretrained("flax-community/bengali-t5-base", config=config)
  ```
  
  The model is trained on `de-noising` objectives followed by the script [here](https://huggingface.co/flax-community/bengali-t5-base/blob/main/run_t5_mlm_flax.py) and [here](https://huggingface.co/flax-community/bengali-t5-base/blob/main/run.sh). Currently This model doesn't have any generation capability. If you want this model to have generation capability, please do a finetuning on `prefix-LM` objective mentioned in the [paper](https://arxiv.org/abs/1910.10683). 
  
  See the tensorboard log in `Training metrics` tab.
  
  Please note that we haven't finetuned the model in any downstream task.
