How to use

Dependencies

• paddlepaddle>=2.0.0
• parl>=1.4.3
• gym==0.12.1
• atari-py==0.1.7
• opencv-python

Distributed Training

At first, we can start a local cluster with 5 CPUs:

xparl start --port 8010 --cpu_num 5

Note that if you have started a master before, you don't have to run the above command. For more information about the cluster, please refer to our documentation

Then we can start the distributed training by running:

python train.py
