thomas-jupyter-widget

A Custom Jupyter Widget Library

Installation

Regular install

$ pip install thomas-jupyter-widget
$ jupyterlab labextension install thomas-jupyter-widget

Development install

For a development installation (requires npm),

$ git clone https://github.com/mellesies/thomas-jupyter-widget.git
$ cd thomas-jupyter-widget
$ pip install -e .
$ jupyter nbextension install --py --symlink --sys-prefix thomas.jupyter
$ jupyter nbextension enable --py --sys-prefix thomas.jupyter
$ jupyter labextension install --minimize=False @jupyter-widgets/jupyterlab-manager@1.0
$ jupyter labextension install --minimize=False js

When actively developing your extension, build Jupyter Lab with the command:

$ jupyter lab --watch

This take a minute or so to get started, but then allows you to hot-reload your javascript extension. To see a change, save your javascript, watch the terminal for an update.

Note on first jupyter lab --watch, you may need to touch a file to get Jupyter Lab to open.

Usage

• Enable extensions in Jupyter Lab (see jupyterlab.readthedocs.io)
• Run the following in a Jupyter Lab notebook:

    import thomas.core
    from thomas.core import get_pkg_data
    from thomas.core import BayesianNetwork, examples
    from thomas.jupyter import BayesianNetworkWidget

    Gs = examples.get_student_network()
    view = BayesianNetworkWidget(Gs)
    display(view)

Evidence can be set by calling the method set_evidence_hard() on the Bayesian Network. Alternatively, you can double click on a state in the Graph.
