Part 1 (2020)

I am running in my local PC and I am trying to install fastai and fastbook to run the notebooks

I am running the follwing command:

conda install -c fastai -c pytorch fastai fastbook

It finished.
then when running the import in the notebook

import fastbook
fastbook.setup_book()

I am getting the following error:

NameError Traceback (most recent call last)

Faced the same issue. Tried the solution to upgrade nbdev mentioned here.

That didnt work. Then downgraded the nbdev version from 1.1.0 to 1.0.18.
After that it worked.
You can downgrade with following command

pip install nbdev==1.0.18

Thank you!
It really solved the problem!
I donā€™t understand why this happened, conda should download the right dependencies by himself.

Thanks, using that version of nbdev worked for me too.

For people using anaconda you can do this too:

conda install -c fastai nbdev=1.0.18
