ImportError: DLL load failed while importing nvdiffrast_plugin: the specified module cannot be found about instantmesh HOT 6 OPEN

Similar error running app.py alone. Confirmed nvdiffrast installed with pip. confirmed able to import with conda env python.

#34

@mlfetsch75 @k1ckmefroml1f3 i found the solution for this not sure whether this is right way to fix it
!) Uninstall previous cuda version from the system
2) install latest cuda toolkit from 12.1 and drivers
3) set the env path for this - should happen by itself but sometimes overwrite issue
4) restart you env .

Long story short, nvdiffrast_plugin is build against CUDA_PATH version, not first (or the only) in PATH. So, delete nvdiffrast_plugin and set correct CUDA_PATH before run.

rmdir /S %userprofile%\AppData\Local\torch_extensions\torch_extensions\Cache\py310_cu121\nvdiffrast_plugin
set CUDA_PATH=C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v12.1\
python app.py

UPD: removed quotes from path, it leads to errors in some cases

Thanks for the fix and reply.

@iiiCpu @sumanttyagi Way simpler than how I was trying to resolve. Thanks very much.
