Bug Description:
When trying to import intel_extension_for_pytorch
, the program fails with an OSError: [WinError 126]
, indicating it cannot load esimd_kernels.dll
or one of its dependencies. This occurs on a new laptop with an Intel Core Ultra 9 285H CPU and an Intel Arc 140T GPU.
Troubleshooting Steps Already Taken:
I have already tried all of the following solutions without success:
- Clean reinstallation of
torch
andintel-extension-for-pytorch
using the official index URL. - Updated all Intel drivers to the latest versions using the Intel Driver & Support Assistant.
- Installed the latest Microsoft Visual C++ 2015-2022 Redistributable (both x64 and x86).
- Manually added the GPU driver directory to the system
PATH
environment variable. - Performed full system shutdowns after making changes.
# All necessary imports at the beginning
