Error while prediction using fastai

[abhigupta4981 (Abhi Gupta)]

So I was trying to predict the results for my test set using the code:

learn.data = (src.add_test_folder('test1-images')
              .transform(tfms, size=224)
              .databunch()
              .normalize(imagenet_stats))
preds, extra = learn.get_preds(ds_type=DatasetType.Test)

and I got an error shown in the picture.

Can someone tell me what is wrong

I was facing same issue with fastai v1.0.24. I upgrade to v1.0.27 and the issue is fixed now.
