Is there any other rerequisites or settings before running "torchpack dist-run..." ? about spvnas HOT 4 CLOSED

I solve this problem by adding '127.0.0.1 localhost:1' to /etc/hosts.

I changed the code into single GPU version (without distributed training) and fix the issue

Hi, I just met the same problem as you and I cannot edit /etc/hosts either. I finally solve the problem without modifying the code.
I find that the common reason to cause this problem Could not resolve hostname xxxxx: Name or service not known is that there exists multiple version of openmpi in the system. You might use an older verison to compile mpi4py and torchpack. You could use the command mpirun --version to see which version of openmpi you are using and then modify the default mpirun path by export PATH="<where/the/newer/mpirun/is>:$PATH". Finally, reinstall mpi4py and torchpack and remember not to use the cached mpi4py and torchpack packages.
Hope this will work for you. More details can be find there.

Dear Woodpecker0:
what if I could not edit /etc/hosts and how I append the '127.0.0.1 localhost:1' to /etc/hosts.
:)
Best!
