Cuda not available for RTX 6000 mobile

I just read on this thread: Error loading "\lib\site-packages\torch\lib\shm.dll" or one of its dependencie - #2 by Alexander_DE (which you’re also on). The error might be due to using pytorch2.3 (which was released quite recently).

Perhaps do a clean install of PyTorch 2.2 and see if the error is resolved?
