i am getting this error for mini imagenet dataset

[AntreasAntoniou]

I am really sorry about this. I recently applied some quick refactoring suggested by sourcery. I checked the changed but it seems this one escaped my attention. I'll resolve this shortly.

[rishabh004-ai]

Thanks a lot.

[AntreasAntoniou]

Can you give it a try now?

[AntreasAntoniou]

I am hoping that 8696470 fixes it.

[rishabh004-ai]

No, I think line 159 in data.py also needs to be changed.

[AntreasAntoniou]

Is this alright now? I triple checked and it runs fine on my local machine.

I think I find the reason.
Please check whether your mini_imagenet_full_size.json is correct.
It would become {} if you did not put the dataset in correct place at the first time you run the script.
Hope this will help!

I have the same problem. Is that right to place file mini_imagenet_full_size.tar.bz2 under the folder 'datasets'? Is there other parameters needed to be modified?

[sherry0451]

I solved my problem as follows. First, automatic unzip code didn't work for my testing, so I unzip the file in terminal manually. Then I deleted the json file for miniimagenet in folder 'dataset'. Then it works.
