Nbdev with Google Colaboratory: A Tutorial

nbdev
21

Thanks for your help @pete88b. Unfortunately, I am still having problems with colab_helper.ipynb. Trying to run setup_project, I encounter the following error:

        project_name = 'nextai'
        config, project_config = setup_project(project_name)

    Error: [nextai] section not found in /content/drive/My Drive/nbdev_colab_projects.ini    
    Please add a section for [nextai] and run `setup_project` again
    See https://pete88b.github.io/nbdev_colab_helper/core.html for details

However, I have the nbdev_colab_projects.ini file in the proper place and filled according to instructions:

[DEFAULT]
project_parent = /content/drive/My Drive/Colab Notebooks/github

git_user_name = jav0927
git_user_email = XXXXXXXX@gmail.com
git_user_password = XXXXXXX

[nextai]
git_url = https://github.com/jav0927/nextai.git
git_branch = main

Looking forward to your comments. I have found using nbdev_colab_helper immensely helpful.

Morning @joseadolfo

This works for me, if I copy your [nextai] section and run setup_project, i see:

git clone https://github.com/jav0927/nextai.git "/content/drive/My Drive/Colab Notebooks/github/nextai"
/content/drive/My Drive/Colab Notebooks/github/nextai
pip install fastscript==1.0.0 fastcore==1.0.8 nbdev==1.0.14
   ...

Sometimes after saving file changes in google drive it takes some time for a notebook to see the change - maybe you got hit with this delay?

Do you have any other project sections that work in your ini file?

@muellerzr Thanks for this great tutorial. Although I haven’t gotten it to the point where I want just yet, I really appreciate the work and explanation. I’m getting an error for the git_push function. I ran !git add * without a problem so I’m not sure why this is happening exactly. Any help would be appreciated.

Here is a copy of the error:
