It seems that your tensor shape is wrong. Check this
my tensoor shape is not wrong.

I try to change SyncBN to BN3d but doesn't work with me when using this cfg.model.backbone.norm_cfg.type= 'BN3d'
when I set r2plus1d_r34.py like below:
error happened:
when I changed r2plus1d_r34.py :
error also changed:
How to fix this problem?
