# LiteCoder Experiment Reproducing package

- To run the pre-train objective use the following scripts:
  
  - Reproduce LiteCoder with all objectives:
    
    - Navigate the folder `Pre-training` containing the `LiteCoder.py` file
    - Then, run `Python LiteCoder.py --train-tt --train-cs --train-pd`
      
      - The pretrained model is released on [hugging face](https://huggingface.co/LiteCoder/LiteCoder_pretrained), therefore it automatically loads.

  - To run the ablation studies:
    
    - Ablation 1: `Python LiteCoder.py --train-tt`
    - Ablation 2: `Python LiteCoder.py --train-tt --train-cs`
    - Ablation 3: `Python LiteCoder.py --train-tt --train-cs --train-pd`

- To `Fine-tuning` LiteCoder on downstream tasks:
  
  - Navigate to the `Fine-tuning` folder and then `Downstream task` folder:
     
    - Code Clone Detection:
      - Follow the instruction of `readme.md` file.
        
    - Code Translation:
      
      - Run `setup.sh` file.
      - Navigate to the `scripts/finetune` and run `translate.sh` file.

- To extract the programming language features (i.e., `token type`, `code sememe`, and `code dependencies`)
  - We used open source datasets to extract language features. we released the extracted datasets on the Hugging Face:
    - `LT_Java` :  [LiteCoder/LT_Java](https://huggingface.co/datasets/LiteCoder/LT_Java)
    - `LT_Python` :  [LiteCoder/LT_Python](https://huggingface.co/datasets/LiteCoder/LT_Python)
    - `LT_Java_Dependency` :  [LiteCoder/LT_Java_Dependency](https://huggingface.co/datasets/LiteCoder/LT_Java_Dependency)

  - Navigate to the utils directory:
    - Use either the `Java` or `Python` notebook file to run over your dataset.
    - Run the cells, for which, you want to extract the features.

- Dependencies:
  - Feature extraction dependencies:
    ```bash
    - pip install ast-comments
    - pip install ast
    - pip install javalang
    - pip install tree-sitter
    
  - Model training dependencies:
    ``` bash
    - pip install transformers 
    - pip install datasets
    - pip install pytorch_lightning
    - pip install torch

  - Or `pip install -r requirements.txt`
