Code Trans T5 Large Source Code Summarization Python Multitask Finetune

🚀 CodeTrans model for source code summarization in Python

This is a pre-trained model for the Python programming language, leveraging the T5 large model architecture. It was initially released in this repository. This model is trained on tokenized Python code functions, and it performs best with such tokenized Python functions.

✨ Features

• Based on the t5-large model with its own SentencePiece vocabulary model.
• Utilizes multi-task training on 13 supervised tasks in the software development domain and 7 unsupervised datasets.
• Fine-tuned for source code summarization of Python code snippets.

💻 Usage Examples

Basic Usage

Here is how to use this model to generate Python function documentation using Transformers SummarizationPipeline:

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.

📚 Documentation

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.

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.

Evaluation results

For the source code summarization tasks, different models achieve the following results on different programming languages (in BLEU score):
