Hi,

I was training the network with validation on coco dataset using 8 gpus on a single node. It seems like the network hangs while using reduce_tensor method inside validate_cls(). Is there a solution known for this issue?

Hi @ayushi-3536

I haven't encountered this issue.

Could you please provide your PyTorch version?

Maybe you could please try run validation first.
