I lack sufficient Python understanding to solve this issue myself.

Oh right, the file. train_vits_win.py.

I've run into the same problem with "_The process cannot access the file because it is being used by another process" while doing some tests on Windows, but i'm not sure how i solved it. But this happens when training already crashed and the process tries cleaning up the training folder.

• Did you run your command line with admin privilieges?
• Is there any file open from the training directory in explorer?

The issue I'm having is primarily the RuntimeError: The expanded size of the tensor (1) must match the existing size (2) at non-singleton dimension 0. Target sizes: [1, 44982]. Tensor sizes: [2, 44982] issue. I don't understand what this is.
