Vision: torchvision transforms broken by Pillow 7.0 release

[felix-ht]

🐛 Bug

Pillow just released 7.0.0. This breaks torchvision.transforms as the import fails:

Traceback (most recent call last):

    from torchvision.transforms import (

To Reproduce

run
from torchvision.transforms import Compose

Environment

torch==1.3.1
torchvision==0.4.2
torchvision==7.0.0

Fix

I pinned pillow to version 6.2.2. After this the import works again

I can confirm this issue when installing https://download.pytorch.org/whl/cpu/torchvision-0.4.2%2Bcpu-cp36-cp36m-linux_x86_64.whl

I still get version 7.0.0 when I install using the following command

pip3 install torch===1.3.1 torchvision===0.4.2 -f https://download.pytorch.org/whl/torch_stable.html

or even using the following command

pip3 install torch===1.3.1 torchvision===0.4.2 -f https://download.pytorch.org/whl/torch_stable.html

It seems like it was fixed here a few months ago: https://github.com/pytorch/vision/commit/b8ef5322b5aea611a6aca2c876578d012b9a890a

But there hasn't been a release that includes it.

Duplicate of https://github.com/pytorch/vision/issues/1712:

We will be releasing a new version of PyTorch and torchvision early next week, so this should be soon fixed.

As @hugovk mentioned in https://github.com/pytorch/vision/issues/1714#issuecomment-570536493, we will be releasing a new version of torchvision early next week, so I believe this can be closed.

Thanks for the reports!
