RuntimeError: Lock objects should only be shared between processes through inheritance

[YanPioneer]

Hi, I have this problem when saving the model "RuntimeError: Lock objects should only be shared between processes through inheritance".

In order to save the model after training, I added a new line of code "logger. save_itr_params (- 1, runner)" in the file "playvirtual-main / Atari / scripts / run. py" after "runner. train()", It should be caused by multi-process data communication. Is there any solution?

Looking forward to your reply, thank you very much.

Sorry for the late reply. I just saw the issue. Have you solved it now? How many CPU cores were in your machine?
