TypeError: cannot pickle '_curses.window' object about pymodes

I guess maybe you can try the Windows Linux Subsystem? https://docs.microsoft.com/en-us/windows/wsl/

Sorry that I don't have a better recommendation, since I haven't used windows for a very long time...

I ran into the same issue on macOS and adding multiprocessing.set_start_method("fork") at the top (before any call that uses multiprocessing) fixed it for me.
