windows multiprocessing error

[lihuiliullh]

I run this code in windows and get a multiprocessing error.

RuntimeError: cuda runtime error (801) : operation not supported at C:\w\1\s\windows\pytorch\torch/csrc/generic/StorageSharing.cpp:245

Do you have windows version code?

Unfortunately the code is not directly supported in windows. PyTorch itself appears to have some difficulties on windows -- it may be possible to get it to run by setting num_workers=0 for all DataLoaders and using the command line --n_workers=1 for all scripts, but I'm unable to test this. Alternatively, you could try setting --device=cpu to avoid cuda altogether, or running the code through windows subsystem for linux? Let me know if these still don't work.
