Contributing

If you want to contribute to this list and the examples, please open a new pull request.

Examples

Example applications or scripts should be submitted in this example folder.

Tutorials

If you have a tutorial idea for the website, download the Jupyter notebook tutorial template.

Tutorial location

Notebook tutorials should be submitted in the docs/tutorials folder, so that they maybe rendered in the web site's tutorial section.

Do not forget to udpdate the docs/tutorials/index.md for your tutorial to show up on the website.

Tutorial formatting

The site expects the format to be markdown, so export your notebook as a .md via the Jupyter web interface menu (File > Download As > Markdown). Then, to enable the download notebook button in the web site's UI (example), add the following as the last line of the file (example):

<!-- INSERT SOURCE DOWNLOAD BUTTONS -->

If you want some lines to show-up in the markdown but not in the generated notebooks, add this comment <!--notebook-skip-line--> after your ![png](img_url). Like this:

![png](img_url.png)<!--notebook-skip-line-->

Typically when you have a plt.imshow() you want the image tag [png](img.png) in the .md but not in the downloaded notebook as the user will re-generate the plot at run-time.

Tutorial tests

As part of making sure all our tutorials are running correctly with the latest version of MXNet, each tutorial is run automatically through a python2 and python3 jupyter notebook kernel in the CI, in a GPU environment, checking for errors and warnings.

Add your own test here tests/tutorials/test_tutorials.py. (If you forget, don't worry your PR will not pass the sanity check).

If your tutorial depends on specific packages, simply add them to this provisioning script: ci/docker/install/ubuntu_tutorials.sh
