Pytorch DataParallel two gpu Hang

[maskjp]

Hi, I have two lambda dual with two TITAN RTX. One pc works fine. But another pc freeze when using Dataparallel.
I got the not working one last mouth.

I tried the solution in this

[solved] DataParallel Multiple V100s Hang

But got an error message.

And I also try to disable iommu following the following methods. But I found that the iommu is already disabled by default.

Issue: Multi-GPU K80s

Are there any other solutions?

Thanks!
