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

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
