Hi,
I’m getting error message in chapter 5 ‘pet breeds’ in this code section:
#id interpolations
#caption A comparison of fastai's data augmentation strategy (left) and the traditional approach (right).
Error is this:
File "<ipython-input-11-0d191734f37a>", line 8
dls1.train.get_idxs = lambda: In f.ones
_________________________________^
SyntaxError: invalid syntax
Can anyone comment on what’s going on in this line of code? And how to fix it?
Full code section copy:
