[JupyterLab](http://jupyterlab.readthedocs.io/en/stable/) is the next-generation user interface for [Project Jupyter](https://jupyter.org) 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](https://www.npmjs.com/) packages that use our public APIs. The _prebuilt_ extensions can be distributed via [PyPI](https://pypi.org/search/?q=jupyterlab&o=-created&c=Framework+%3A%3A+Jupyter), conda, and other package managers. The _source_ extensions can be installed directly from npm (search for [jupyterlab-extension](https://www.npmjs.com/search?q=keywords:jupyterlab-extension)) but require an additional build step. You can also find JupyterLab extensions exploring GitHub topic [jupyterlab-extension](https://github.com/topics/jupyterlab-extension). To learn more about extensions, see the [user documentation](https://jupyterlab.readthedocs.io/en/stable/user/extensions.html). Read the current JupyterLab documentation on [ReadTheDocs](http://jupyterlab.readthedocs.io/en/stable/). > [!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](https://blog.jupyter.org/jupyterlab-3-end-of-maintenance-879778927db2) on the Jupyter Blog. --- ## Getting started ### Installation If you use [conda](https://docs.conda.io/en/latest/), [mamba](https://mamba.readthedocs.io/en/latest/), or [pip](https://docs.python.org/3/installing/index.html), you can install JupyterLab with one of the following commands. - If you use conda: ```shell conda install -c conda-forge jupyterlab ``` - If you use mamba: ```shell mamba install -c conda-forge jupyterlab ``` - If you use pip: ```shell pip install jupyterlab ``` If installing using `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](http://jupyterlab.readthedocs.io/en/stable/getting_started/installation.html). Project installation instructions from the git sources are available in the [contributor documentation](CONTRIBUTING.md). #### Installing with Previous Versions of Jupyter Notebook 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: ```bash jupyter se
