SyncBatchNorm #32

Closed taeyeopl closed 4 years ago

taeyeopl commented 4 years ago

I used the mmdetection from f3a939f It seems like torch 0.4.1 don't support the SynBatchNorm Libraray which is in the mmdetection part.

Can I ask the how to handle SyncBatchNorm.

AttributeError: module 'torch.nn' has no attribute 'SyncBatchNorm'

The problem was solved by changing mmcv version 0.2.0
