| # CodeTrans model for source code summarization python |
| Pretrained model on programming language python using the t5 large model architecture. It was first released in |
| [this repository](https://github.com/agemagician/CodeTrans). This model is trained on tokenized python code functions: it works best with tokenized python functions. |
|
|
|
|
| ## Model description |
|
|
| This CodeTrans model is based on the `t5-large` model. It has its own SentencePiece vocabulary model. It used multi-task training on 13 supervised tasks in the software development domain and 7 unsupervised datasets. It is then fine-tuned on the source code summarization task for the python code snippets. |
|
|
|
|
|
|
| ## Intended uses & limitations |
|
|
| The model could be used to generate the description for the python function or be fine-tuned on other python code tasks. It can be used on unparsed and untokenized python code. However, if the python code is tokenized, the performance should be better. |
|
|
| ### How to use |
|
|
| Here is how to use this model to generate python function documentation using Transformers SummarizationPipeline: |
|
|
| ```python |
| from transformers import AutoTokenizer, AutoModelWithLMHead, SummarizationPipeline |
| |
| pipeline = SummarizationPipeline( |
| model=AutoModelWithLMHead.from_pretrained("SEBIS/code_trans_t5_large_source_code_summarization_python_multitask_finetune"), |
| tokenizer=AutoTokenizer.from_pretrained("SEBIS/code_trans_t5_large_source_code_summarization_python_multitask_finetune", skip_special_tokens=True), |
| device=0 |
| ) |
| |
| tokenized_code = '''with open ( CODE_STRING , CODE_STRING ) as in_file : buf = in_file . readlines ( ) with open ( CODE_STRING , CODE_STRING ) as out_file : for line in buf : if line == " ; Include this text " : line = line + " Include below " out_file . write ( line ) ''' |
| pipeline([tokenized_code]) |
| ``` |
| Run this example in [colab notebook](https://github.com/agemagician/CodeTrans/blob/main/prediction/multitask/fine-tuning/source%20code%20summarization/python/large_model.ipynb). |

|
|
| The supervised training tasks datasets can be downloaded on [Link](https://www.dropbox.com/sh/488bq2of10r4wvw/AACs5CGIQuwtsD7j_Ls_JAORa/finetuning_dataset?dl=0&subfolder_nav_tracking=1) |

|
|
| ## Training procedure |
|
|
| ### Multi-task Pretraining |
|
|
| The model was trained on a single TPU Pod V3-8 for 500,000 steps in total, using sequence length 512 (batch size 4096). |
| It has a total of approximately 220M parameters and was trained using the encoder-decoder architecture. |
| The optimizer used is AdaFactor with inverse square root learning rate schedule for pre-training. |
|
|
| ### Fine-tuning |
|
|
| This model was then fine-tuned on a single TPU Pod V2-8 for 100 steps in total, using sequence length 512 (batch size 256), using only the dataset only containing python code. |
