thanks, this actually worked, though I got extremely strange validation scores all over the place while training (but ending up in a good place in the end). Have you seen similar behaviour?
2 little things, maybe you can edit your post: it is actually cols not col, and I also had to specify the folder because otherwise there was a ‘./’ added in the middle of the path (though that seems a bug in fastai?)
Thanks again!
ah, and metrics always crashed the code, so I had to remove metrics. Did accuracy and error rate work for you? Did you use other metrics you wrote yourself?
