Stuck on first jupyter notebook example: ModuleNotFoundError

Part 1 (2019)
1

Hi, I’m using paperspace + fast ai for setup.

I followed steps from Paperspace Gradient | Practical Deep Learning for Coders

after opening my jupyter notebook from paperspace, created selecting “Paperspace + fast.ai” runtime, using free GPU.

I open 01_intro.ipynb and the first code block

#hide

!pip install -Uqq fastbook

import fastbook

fastbook.setup_book()

returns following code block with bunch of errors

any help would be appreciated. thank you

I am also getting the same error. But on Google colab it is running fine.

thanks for replying, seems to work fine on colab for me as well.
I will use this for time being.

4

I had same issue. I wonder if it’s because i can’t use the terminal on the free version to pull the most recent git repo?

In trying to run some other stuff too (the basic examples) I gave up after 10+ minutes of waiting.

I’m using Gradient Paperspace, and yeah, you’ll have issues unless you get a subscription. If you want to go the free route, Collab is definitely better.

I got this error when trying to run the ‘01_intro.ipynb’ notebook from the root folder. For me (and I don’t know why), it runs fine when I go to the version in the ‘clean’ folder (clean\01_intro.ipynb).
Using free Paperspace.

@hiby thanks, that worked for me as well :slight_smile:

This did not work for me. Tried creating a fresh notebook and upgrading fastbook but it still doesn’t work. I’m using Paperspace.

I was able to bypass this error by running it on Jupyter
