A3C Doom: Why there should be no more workers than there are threads on CPU?

[ZhanPython]

Hi there,

The number of available CPU threads in my machine should be 16. However, I tested the number of workers in CPU only A3C-Doom because I set, import os os.environ["CUDA_VISIBLE_DEVICES"]="" import tensorflow Actually, there can be more workers than 16. I'm confused about this. Do you have any ideas about why?
