Running course notebooks locally (01_intro.ipynb)

Hi,

Being frustrated by Voila not working on Google Colab (I’m not able to proceed with the instructions related to app deployment via Voila/Binder, as given in Lesson 2), I’m trying to run course notebooks on my machine (mac).
After installing Anaconda, as well as Fastai (by using conda install -c fastai -c pytorch -c anaconda fastai gh anaconda) and trying to run the very first cell with fastbook setup I’m getting the following cryptic message(s): “AttributeError: ‘str’ object has no attribute ‘stored_args’”

I’m attaching the screenshot.
Asking Fastai community for help :slight_smile:


Thanks!

Perhaps check that you’ve installed fastbook in Anaconda directly (using $ conda list in Bash)? If not, perhaps try $ conda install fastbook -c fastai?

Thanks for that. Tried that (conda list shows “fastbook version 0.0.9”), still the same problem. Basically, if I am to run the course notebooks locally what is that that needs to be done/installed?
What I’ve done is downloaded the courses notebooks (via Download zip from fastai’s Github, run the pip install requirements.txt, now trying to run a course notebook in Anaconda. Still getting the same Attribute Error when running the very first cell (import fastbook).

Hmmm… Afraid I’m not sure then. If it’s any help, here’s the result of my $ conda list with a working local environment (on an Ubuntu 20.04 system).

This is the type of error I get when trying to import * from fastai.vision.all (see below).

Any help appreciated!

Yeah, this is exactly the error I have right now after just setting up a Windows installation and running the import cell at the top of lesson 1.

Fixed it by downloading the latest fastai source from github again, deleting my existing folder (which I had called “fastai2”, btw) and extracting the github .zip to “fastai-master” and then renaming that new folder to be just “fastai”. Started my kernel again, and all fixed now.

Note that I had followed the steps written in Deploy fastai-v2 model on windows machine in the meantime, gotten the “No module named ‘fastai2’” error mentioned on that page and then updated my fastai source, but I then went back and tried the environment and kernel I already had when I was getting the error on this page, and it’s still fixed, so I think the issue is simply using a version of fastai with a bug in…

Awesome. Managed to make it work by following the same steps (downloading the latest fastai source, etc.). Thanks!

I thought I would share how I got local setup working without a lot of a hassle.

I am assuming one has already cloned the repo https://github.com/fastai/course-v4 and it is on the repo folder.

To get it working I have updated my environment.yml to the snippet below , (There is PR to get this merged).

name: fastai
channels:
- fastai
- pytorch
- defaults
dependencies:
- jupyter
- pytorch>=1.3.0
- torchvision>=0.5
- matplotlib
- pandas
- requests
- pyyaml
- fastprogress>=0.1.22
- pillow
- python>=3.6
- scikit-learn
- scipy
- spacy
- pip
- pip:
  - graphviz
  - fastbook

Now one can create an environment using :

conda env create --file environment.yml

To activate the environment:

conda activate fastai

And to run the jupyter notebooks:

jupyter notebook

Hope this helps out those that want to run this locally.
In case you have conflict because fastai environment already exists, you can give it a new name, or remove it. I recommend removing the older environment (if you can).

To replace and old fastai environment with the new suggest one follow these steps:

conda deactivate
conda env remove --name fastai
conda env create --file environment.yml
conda activate fastai
