Hi, thank you very much for providing such a good open source algorithm, but I am having the problems when running "main.py" on windows.

How can I solve the problems? Thank you very much.

The error seems to be related to the log directory. Can you verify if the log directory was created successfully? Windows might not support such a long string (the code has only been tested in ubuntu). Maybe you can change this line to use a different log directory name.

I solve the problems according your comments that I manual set the directory name of “log_dir”. Thank you very much.
