pythreejs

A Python / ThreeJS bridge for Jupyter Widgets.

Installation

Using pip:

pip install pythreejs

or conda:

conda install -c conda-forge pythreejs

> For a development install, see the contributing guide.

The extension should then be installed automatically for your Jupyter client.

> For JupyterLab <3, you may also need to ensure nodejs is installed, and > rebuild the application: > > bash > # conda install -c cond-forge 'nodejs>=12' > jupyter lab build >

Troubleshooting

If the extension is not automatically installed, you can manually enable it

Jupyter Notebook Classic

jupyter nbextension list
jupyter nbextension install --py --symlink --sys-prefix pythreejs
jupyter nbextension enable --py --sys-prefix pythreejs
jupyter nbextension list

You should see:

Known nbextensions:
  ...
  jupyter-js-widgets/extension  enabled
    - Validating: OK

> Note for developers: the --symlink argument on Linux or MacOS allows one to > modify the JavaScript code in-place. This feature is not available on Windows.

JupyterLab

To perform a source installation:

## ensure you have nodejs install, e.g. with conda
# conda install -c conda-forge 'nodejs>=12'
jupyter labextension list
jupyter labextension install --no-build @jupyter-widgets/jupyterlab-manager
jupyter labextension install --no-build jupyter-datawidgets/extension
jupyter labextension install jupyter-threejs
jupyter labextension list

You should see:

JupyterLab v...
  ...
    jupyterlab-datawidgets v... enabled OK
    @jupyter-widgets/jupyterlab-manager v... enabled OK
    jupyter-threejs v... enabled OK

> This approach is not recommended for JupyterLab 3, which enables > federated modules, installed via pip, conda or other package managers, > and does not require rebuilding the entire application.

Uninstallation

Using pip:

pip uninstall pythreejs

or conda:

conda uninstall pythreejs

> If you applied any manual steps above, it may be necessary to remove the

Jupyter Notebook Classic

jupyter nbextension disable --py --sys-prefix pythreejs

Jupyter Lab

jupyter labextension uninstall jupyter-threejs
