docs: Download, prepare and install a compressed tar file from S3 or provided directory as a module.
      SageMaker Python SDK saves the user provided scripts as compressed tar files in S3
      https://github.com/aws/sagemaker-python-sdk.
      This function downloads this compressed file, if provided, and transforms it as a module, and installs it.
      Args:
          name (str): name of the script or module.
          uri (str): the location of the module.
          cache (bool): default True. It will not download and install the module again if it is already installed.
      Returns:
          (module): the imported module
