vanity-widget v0.1.0

vanity

A Custom Jupyter Widget Library for multi modal analysis of video. Only tested on chrome/chromium based browsers

Requirements

• Node version 15
• Python 3.8

Development Installation

$ git clone git@github.com:imandel/vanity.git

Now install the dependencies:

$ npm i
$ pip install pandas

First install the python package. This will also build the JS packages.

pip install -e .

Enable the extension

$ jupyter nbextension install --sys-prefix --symlink --overwrite --py vanity
$ jupyter nbextension enable --sys-prefix --py vanity

Run these command in two separate windows:

$ npm run watch

and the second command:

$ jupyter notebook

Open your browser by clicking the link provided in the jupyter terminal. Navigate to "examples" and then click the "introduction.ipynp" link.

Firefox support

There is a weird bug running this app with firefox.

jupyter notebook --generate-config

Edit the config file :

vi .jupyter/jupyter_notebook_config.py

Change "c.NotebookApp.allow_origin" from "" to "*"

See this issue for more information:

Windows support

Note that the --symlink flag doesn't work on Windows, so you will here have to run the install command every time that you rebuild your extension. For certain installations you might also need another flag instead of --sys-prefix, but we won't cover the meaning of those flags here.

How to see your changes

Java/Typescript:

To continuously monitor the project for changes and automatically trigger a rebuild, start Jupyter in watch mode:

begin watching the source directory for changes:

npm run watch

After a change wait for the build to finish and then refresh your browser and the changes should take effect.

Python:

If you make a change to the python code then you will need to restart the notebook kernel to have it take effect.

Example File

The introduction file has a test example you should be able to download and get running.
