[bingsanyu]

Key Changes

1. requirements.txt Updates:

   • Added new dependencies:
     • ipykernel
     • torch_geometric
     • wandb
   • Removed torch from the list of dependencies since its installation is explicitly covered in the README (PyTorch installation with the correct CUDA version).

2. README.md Updates:

   • Added test for Windows under the "Environment" section.
   • Moved the PyTorch installation step before dependency installation.

3. engine_real.py Updates:

   • Added import os to the list of imports.

Testing

The updates have been tested in environments with Windows10, using Python 3.9.20 and PyTorch 1.12.1.
