Hello, I am a new comer in fastai; When using learn.lr_find(); it reports:
AttributeError: ‘NoneType’ object has no attribute 'update’
This is code; I suppose, DataLoaders has been past successfully by checking src.show_batch().
This is AttributeError:
I have check it online, saying it is due to version; however, I am using fastai == 2.5.3
