I was doing 06_multicat notebook and run into strange error (in the Regression part on the notebook): AttributeError: 'NoneType' object has no attribute 'append' ,
after I try to learn.lr_find().
learn.fine_tune(3, 1e-2) also doesn’t work and throws the same error.
I have done previous notebooks and it was all fine. I didn’t change the code you have provided in this part. The forums don’t seem to have the answer for this.
I’m no expert, but it looks like there is a problem with cbs, whatever it is, and I found that it is a parameter in cnn_learner and it defaults to None. So, not sure how to go about it.
