AttributeError: 'NoneType' object has no attribute 'CONTRASTIVE'

[FeSCN6]

I met this problem here:

It seems that the class ResNetBasicHead(slowfast/models/head_helper.py) needs CONTRASTIVE, but I couldn't find any setting concerning CONTRASTIVE in .yaml file. : (

In build_model where ResNetBasicHead is initalized, pass cfg as an argument:
model.head = ResNetBasicHead(cfg =cfg ,...)
