Hi guys,
had the same error message as above, on my 1st machine
on my first machine, after creating it, i had run git pull and conda env update as shown in lesson 1 video.
so i recreated a machine using the Fastai template but this time i did not run git pull and conda env update, and now i can run all the commands in the notebook without any error. So it looks like the template is set properly, we should not modify it afterwards.
