Hi.
I’m currently going through Lesson 2 using the ClassConfusion class in Google Colab in the following way:
ClassConfusion(interp, classes, is_ordered=False, figsize=(8,8))
When I ran the cell, I was asked to enter a value for ‘k’, or the top images you will see. I didn’t know what this was about so I entered 5. I was met with the following error message:
0%| | 0/3 [00:00<?, ?it/s] 0%| | 0/3 [00:00<?, ?it/s]
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)

93 fn = self.interp.data.valid_ds.x.items[idx]
---> 94 fn = re.search('([^/*]+)_\d+.*$', str(fn)).group(0)
95 img.show(ax=ax[row, col])
96 ax[row,col].set_title(fn)
AttributeError: 'NoneType' object has no attribute 'group'
I know that we can’t really use widgets in Colab but I was under the impression that ClassConfusion would remedy that problem. Its my 1st time ever using it and I am a newbie so this is most likely on me.
Thank you.
