Cap Pillow and other dependencies

[pvk-developer]

There have been some updates to Pillow which makes Torchvision to fail trying to import PILLOW_VERSION from PIL.

There's now a new release of torchvision (0.5.0) that works with the newest Pillow version (7.0.0).

• https://github.com/pytorch/vision/releases/tag/v0.5.0
• New Pillow version (7.0.0) breaks torchvision (ImportError: cannot import name 'PILLOW_VERSION' from 'PIL') pytorch/vision#1712

An alternative to #52 is updating the torchvision pin from 0.2.1 to 0.5.0.

Hi @hugovk and thank you for your anwser. I will check out if SteganoGAN is working properly with that version of torchvision and if everything is okay I will proceed to update it to torchvision==0.5.0 .

Update:

  ERROR: torchvision 0.5.0 has requirement torch==1.4.0, but you'll have torch 1.0.0 which is incompatible.

Unfortunately we are using torch 1.0.0 and at the moment we are not planing to update it to 1.4.0 or bigger. I belive that we will go on installing everything as it was from development and just dedicate more time on updating the code in the future.

You can also now upgrade to Pillow 7.1.0+, which reintroduced PILLOW_VERSION to allow projects some more time to update.
