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.
[!IMPORTANT] JupyterLab 3 reached its end of maintenance date on May 15, 2024. Fixes for critical issues will still be backported until December 31, 2024. If you are still running JupyterLab 3, we strongly encourage you to upgrade to JupyterLab 4 as soon as possible. For more information, see JupyterLab 3 end of maintenance on the Jupyter Blog.
If you use conda, mamba, or pip, you can install JupyterLab with one of the following commands.
conda install -c conda-forge jupyterlab
mamba install -c conda-forge jupyterlab
pip install jupyterlab
pip install --user, you must add the user-level bin directory to your PATH environment 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".For more detailed instructions, consult the installation guide. Project installation instructions from the git sources are available in the contributor documentation.
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:
jupyter lab
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:
See our documentation for additional details.
We encourage you to ask questions on the Discourse forum. A question answered there can become a useful resource for others.
To report a bug please read the guidelines and then open a Github issue. To keep resolved issues self-contained, the lock bot will lock closed issues as resolved after a period of inactivity. If a related discussion is still needed after an issue is locked, please open a new issue and reference the old issue.
We also welcome suggestions for new features as they help make the project more useful for everyone. To request a feature please use the feature request template.
To start developing an extension for JupyterLab, see the developer documentation and the API docs.
