Fastai on PaperSpace Gradient not working

Just paid my 8 dollars for gradient and when I run lesson 1 of fastai.

It faults at statement 2 : from fastai.imports import *

with

ModuleNotFoundError Traceback (most recent call last)
in ()
1 # This file contains all the main external libs we’ll use
----> 2 from fastai.imports import *

ModuleNotFoundError: No module named ‘fastai’

With absolute beginers this should run right from get go - not a good start. Has anybody any suggestions please.

Apologies - I don’t know how I cured this problem but I suspect it was by deleting all the notebooks and starting again. Anyway everthing is working as it should and the first lesson completed successfully. I am on my way.

fyi - I still hit this error at random. The fix for me has been to delete that notebook and start a new one…very annoying.
