This is PyTorch implementation of A3C as described in Asynchronous Methods for Deep Reinforcement Learning.
Since PyTorch has a easy method to control shared memory within multiprocess, we can easily implement asynchronous method like A3C.
python run_a3c.py --atari
In default settings, num_process is 8. Set it as python run_a3c --num_process 4
to fit your number of cpu's cores.
After training
python test_a3c.py --render --monitor
