    It is a Pytorch model implementation task;
    All the things are placed in a folder.

    Folder
    - data source and documents prepared by `prepare`
        - Please note that new data may be passed in dynamically in `execute`
    - code (file `model.py` ) injected by `inject_code`
        - the `model.py` that contains a variable named `model_cls` which indicates the implemented model structure
            - `model_cls` is a instance of `torch.nn.Module`;

    We support two ways of interface:
        (version 1) for qlib we'll make a script to import the model in the implementation in file `model.py` after setting the cwd into the directory
            - from model import model_cls
            - initialize the model by initializing it `model_cls(input_dim=INPUT_DIM)`
            - And then verify the model.

        (version 2) for kaggle we'll make a script to call the fit and predict function in the implementation in file `model.py` after setting the cwd into the directory
