it might be something wrong with your dataset. Make sure the path is correct and the dataset is well processed, You can try if it fails on all the methods.

The problem is with the mini-imagenet download file, referenced in README.md. The script searches for .jpg files, but the download contains pickle files.

Hey, @millermuttu did you solve your problem? Could you share it here? I have the sample problem for Omniglot

Oops, never mind. @ChenjieSun Thanks for the solution

I had the same problem and I had solved it. You must make sure that your file 'images_background' is in folder 'DATA_PATH + '/miniImageNet'', or your 'self.df' will be empty.
