I want to ask you about this step in Rossmann, respectively it’s consequences for the DL model
joined = joined[joined.Sales!=0]
I thought it’s sort of a business decision whether to include zero sales or not and in the lecture these were excluded to be aligned with original approach.
For me zero dependent variable seems to be a valid value (especially in other datasets), but when I remove this line the model goes weird…
- lr_find() doesn’t return error but also plot is empty
- trn_loss and val_loss are nan in all epochs etc.
Have you tried this and do you get same results? Do you know why it should be happening?
Thanks a lot for any explanation
