An extensible environment for interactive and reproducible computing, based on the Jupyter Notebook and Architecture.
JupyterLab is the next-generation user interface for Project Jupyter offering all the familiar building blocks of the classic Jupyter Notebook (notebook, terminal, text editor, file browser, rich outputs, etc.) in a flexible and powerful user interface.
JupyterLab can be extended using npm packages that use our public APIs. The prebuilt extensions can be distributed via PyPI, conda, and other package managers. The source extensions can be installed directly from npm (search for jupyterlab-extension) but require an additional build step. You can also find JupyterLab extensions exploring GitHub topic jupyterlab-extension. To learn more about extensions, see the user documentation.
Read the current JupyterLab documentation on ReadTheDocs.
conda install -c conda-forge jupyterlab
mamba install -c conda-forge jupyterlab
If installing using
pip install jupyterlab
pip install --user, you must add the user-level
bindirectory to your
PATHenvironment variable in order to launch
jupyter lab. If you are using a Unix derivative (e.g., FreeBSD, GNU/Linux, macOS), you can do this by running
export PATH="$HOME/.local/bin:$PATH". If you are using a macOS version that comes with Python 2, run
When using a version of Jupyter Notebook earlier than 5.3, the following command must be run after installing JupyterLab to enable the JupyterLab server extension:
jupyter serverextension enable --py jupyterlab --sys-prefix
Start up JupyterLab using:
JupyterLab will open automatically in the browser. See the documentation for additional details.
If you encounter an error like "Command 'jupyter' not found", please make sure
PATH environment variable is set correctly. Alternatively, you can start up JupyterLab using
~/.local/bin/jupyter lab without changing the
PATH environment variable.
The latest versions of the following browsers are currently known to work:
