Non-existent config key when loading EffNets

[JJGO]

I'm unable to load the efficient modules. There seems to be an issue with the MODEL.ACTIVATION_FUN config key. I installed the latest version using pip and tried executing the following piece of code

from pycls.models import effnet
effnet('B0')

If I edit the cache file under /tmp/pycls-download-cache/dds_baselines/effnet/EN-B0_dds_8gpu.yaml and comment out that key then the loading works.

Hey @JJGO, got the same error, probably the pip package is not up to date. However, you can directly install from Github instead via

pip install git+https://github.com/facebookresearch/pycls@master

solved the issue for me
