you can write ‘cnn_learner’ insted. vision_learner used in the upgradet version

thank you for reply. it works now

thank you. I changed nothing, just rerun it and it works now.

For those that were confused like me, this is not a git-pull upgrade… but a terminal upgrade:

pip3 install --upgrade fastai

Hello. I have the same issue. Upgrading fastai does not solve it.

Try changing vision_learner with cnn_lerner

I’m also getting this issue in my notebook on Kaggle. Switching to “cnn_learner” fixes the problem.
