I got the same error. Issue was that newer timm library was getting installed that didn’t seem to be compatible with the notebook. Setting the timm library to the exact version fixed the issue for me (though session has to be restarted for it to work, just rerunning this code won’t overwrite the library with the older version)
Change:
path = setup_comp(comp, install=‘fastai “timm>=0.6.2.dev0”’)
→
path = setup_comp(comp, install=‘fastai “timm==0.6.2.dev0”’)
