Thanks for sharing more details. Three questions:


Since you are using file:///home/storage15/huangying/tools/espnet/egs2/voxforge/asr1/vox.init as the init_method, I assume all ranks can access the same file to rendezvous?


I haven’t tried this within a docker. What is the reason for setting it to ^lo,docker instead of just lo? And does it work if you set it to eth0 or eth1?


What does it return when you run the following command?


getent hosts `hostname`
