🚀 Feature

Update torchvision to 0.5.0 (pip install downgrades to 0.4.2)

ERROR: torchvision 0.4.2 has requirement torch==1.3.1, but you'll have torch 1.4.0 which is incompatible.

Upgrade dependency so that the above doesn't happen.

Motivation

I recently conda installed pytorch and it came with torchvision-0.5.0. However, after pip installing lightning, it downgraded to torchvision-0.4.2.

Pitch

Support the latest torchvision.

Hi, thanks for your suggestion. We have already dropped torchvision dependency #797
Pls, it will be released in 0.6.1 or you can use actual master :]
