It seems that fastai 2.3.1 requires PyTorch version <1.8, which is unfortunate since I need to use some utility functions that are only available in torchvision 0.9.1. Anyone know what the release cycle is like or when the latest version would be compatible?
This gives you a working system albeit with lots of messages.
!pip install torchtext==0.8.1
!pip install -Uqq fastbook
from fastai import *
