Hi,
I changed it in the following way, without the intended effect though. It still returns nan.
fbeta = FBeta(average='weighted')
learn = create_cnn(data, models.resnet50, metrics=[error_rate, fbeta],
callback_fns=ShowGraph)
This is what you mean with passing a function right?
By the way, passing macro instead of weighted does work. So maybe its due to this argument. I’m interested in the weighted error though!
