H-Huang:

You are using world_size=2 and you specify rank=0, are you also initializing another worker with rank=1?


Yes, I try make it with denoiser/executor.py at master · facebookresearch/denoiser · GitHub 4 and denoiser/distrib.py at master · facebookresearch/denoiser · GitHub 2



 H-Huang:

If you are using multiple docker containers, since you are using the file init method, you should ensure that both containers can read/write to the same file. You can do this by using a shared volume between containers.


No, it’s simple case with only one docker launch.
