DeepSpeed library

To build wheel on Windows:
    1. Install pytorch, such as pytorch 1.8 + cuda 11.1
    2. Install visual cpp build tool
    3. Launch cmd console with Administrator privilege for creating required symlink folders

Create a new wheel via the following command:
    python setup.py bdist_wheel

The wheel will be located at: dist/*.whl
