#
# Strengths (over official IPEX 2.0.110 windows release):
# - AOT build (for Arc GPU only) to eliminate JIT compilation overhead: https://github.com/intel/intel-extension-for-pytorch/issues/399
# - Bundles minimal oneAPI 2023.2 dependencies into the python wheels, so users don't need to install oneAPI for the whole system.
# - Provides a compatible torchvision wheel: https://github.com/intel/intel-extension-for-pytorch/issues/465
# Limitation:
# - Only works for python 3.10
