This process used to work for me but it doesn’t anymore. I don’t know why but I am suspecting it has to do with active development of fastai so might be broken recently (1-2 days ago I think). After running the script and reboot, ssh into it again, running jupyter notebook gives me the following error (fastai env activated by default).
$ jupyter notebook

A good way to prevent regression would be lock the dependency versions and also not just git clone the latest but check out only the stable versions, I think. Does anybody have the same problem ?
