Cannot find reference 'efficientnet_blocks' in 'init.py'

All non model modules were prefixed with _ in latest timm versions, so you likely have mismatched version code as nothing in curren timm would use from timm.models.efficientnet_blocks import , it'd be from timm.models._efficientnet_blocks import

problem solved, thanks!
