How did you install intel_extension_for_pytorch?
You can use the release binaries if you don't need to modify the source code

How did you install intel_extension_for_pytorch? You can use the release binaries if you don't need to modify the source code

I installed IPEX according to intel's guidelines, and the environment was fine until the driver update

[CarlGao4]

I think I've found the error. IPEX requires its modified PyTorch and torchaudio and torchvision. You PyTorch version is 2.1.2+cpu, but it's modified version should be 2.1.0a0 as I remember.

Please try uninstalling torch, torchaudio and torchvision first, and install them following the IPEX installation instructions

I think I've found the error. IPEX requires its modified PyTorch and torchaudio and torchvision. You PyTorch version is 2.1.2+cpu, but it's modified version should be 2.1.0a0 as I remember.

Please try uninstalling torch, torchaudio and torchvision first, and install them following the IPEX installation instructions

I tried to install IPEX v2.3.110+xpu, although there was a PIP error

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
demucs 4.1.0a3 requires torchaudio<2.2,>=0.8, but you have torchaudio 2.3.1.post0+cxx11.abi which is incompatible.

But the program worked fine, with no errors

IPEX installation instructions
