On a fresh colab instance, running:
!pip3 install fastai
torchvision 0.2.1 has requirement pillow>=4.1.1, but you'll have pillow 4.0.0 which is incompatible.
The full output of the command is here.
Is this an issue with the dependencies given in the
fastai-1.0.39-py3-none-any.whl package, or am I missing something?
