TypeError: _open() got an unexpected keyword argument 'as_gray'

Describe the bug I pretty much followed the classification tutorial and changed the dataset to my own dataset and I receive an imread error of similar nature to a very old issue #472

TypeError: Caught TypeError in DataLoader worker process 0.

To Reproduce I have cloned notebook which should download my dataset here and should replicate the issue.

Expected behavior It should start outputting the Epoch’s Accuracies etc just like example Artist dataset should.

@Scitator I’ve checked all the images using ImageMagick by converting everything to JPG if they weren’t already JPG

@YaLTeR Unfortunately I still get the error in the notebook with that particular change

@lokeshkvn yup, utils.imread is mostly focused on typical image formats, like .jpg, .png etc. For .tiff, .gif - you can try to use utils.mimread instead 😃 Nevertheless, PR with appropriate docs (that you find clear to use and read) would be really welcome, thanks in advance!
