Describe the bug

When following README.md to install the GPU version of IPEX:

python -m pip install torch==2.0.1a0 torchvision==0.15.2a0 intel_extension_for_pytorch==2.0.110+xpu -f https://developer.intel.com/ipex-whl-stable-xpu

It returned the following error:

ERROR: Could not find a version that satisfies the requirement torch==2.0.1a0 (from versions: 1.11.0, 1.12.0, 1.12.1, 1.13.0, 1.13.1, 2.0.0, 2.0.1, 2.1.0)
ERROR: No matching distribution found for torch==2.0.1a0

Tried with both Python 3.9 and 3.10.

The instruction on this page is works properly:

python -m pip install torch==2.0.1a0 torchvision==0.15.2a0 intel_extension_for_pytorch==2.0.110+xpu --extra-index-url https://pytorch-extension.intel.com/release-whl/stable/xpu/us/

Versions

2.0.110+xpu

This is most likely a network issue. Pip was not able to access the developer.intel.com domain webpage to retrieve available package list.
By the way, https://developer.intel.com/ipex-whl-stable-xpu will be deprecated in the future. Please use https://pytorch-extension.intel.com/release-whl/stable/xpu/us/
