Cannot run: run_apex_ddpg.py

[Deleted user]

I am using Windows 10. When I ran run_apex_ddpg.py, I got:
Traceback (most recent call last):
File "", line 1, in
File "C:\Miniconda3\lib\multiprocessing\spawn.py", line 105, in spawn_main
exitcode = _main(fd)
File "C:\Miniconda3\lib\multiprocessing\spawn.py", line 115, in _main
self = reduction.pickle.load(from_parent)
AttributeError: Can't get attribute 'policy_fn' on <module 'mp_main' from 'C:\tf2rl-master\examples\run_apex_ddpg.py'>

Hi @cubicgate , sorry for late reply. I just didn't notice this issue.

We have changed the ApeX codes so that it passes unittest on Windows machine through GitHub Actions, so it should successfully run now.
However, we haven't tested training an agent on real environments since we don't have local Windows machine.
So, could you test the same command and let me know the results?

Thanks!
