Installation

Using pip

pip install ipycanvas

Using conda

conda install -c conda-forge ipycanvas

JupyterLab extension

If you have JupyterLab, you will also need to install the JupyterLab extension. In order to install the JupyterLab extension, you will need npm to be installed. You can easily install npm with conda:

conda install -c conda-forge nodejs

Then you can install the JupyterLab extension:

jupyter labextension install @jupyter-widgets/jupyterlab-manager ipycanvas

Development installation

For a development installation (requires npm):

git clone https://github.com/martinRenou/ipycanvas.git
cd ipycanvas
pip install -e .

# If you are developing on the classic Jupyter Notebook
jupyter nbextension install --py --symlink --sys-prefix ipycanvas
jupyter nbextension enable --py --sys-prefix ipycanvas

# If you are developing on JupyterLab
jupyter labextension develop . --overwrite
jlpm run build

If you use JupyterLab to develop then you can watch the source directory and run JupyterLab at the same time in different terminals to watch for changes in the extension’s source and automatically rebuild the extension.

# Watch the source directory in one terminal, automatically rebuilding when needed
jlpm run watch
# Run JupyterLab in another terminal
jupyter lab
