    """Copy current running source code folder to model_dir, to enable Estimator.deploy()
    PyTorch framework containers will load custom inference code if:
    - The code exists in a top-level code/ folder in the model.tar.gz
    - The entry point argument matches an existing file
    ...So to make one-click estimator.deploy() work (without creating a PyTorchModel first), we need
    to:
    - Copy the current working directory to model_dir/code
    - `from inference import *` because "train.py" will still be the entry point (same as the training job)
