An extensible environment for interactive and reproducible computing, based on the Jupyter Notebook and Architecture. Currently ready for users.
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 will eventually replace the classic Jupyter Notebook.
JupyterLab can be extended using npm packages that use our public APIs. To find JupyterLab extensions, search for the npm keyword jupyterlab-extension or the GitHub topic jupyterlab-extension. To learn more about extensions, see the user documentation.
The current JupyterLab releases are suitable for general usage, and the extension APIs will continue to evolve for JupyterLab extension developers.
Read the latest version's documentation on ReadTheDocs.
JupyterLab can be installed using
pip. For more detailed instructions, consult the installation guide.
Project installation instructions from the git sources are available in the contributor documentation.
If you use
conda, you can install it with:
conda install -c conda-forge jupyterlab
If you use
pip, you can install it with:
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 (FreeBSD, GNU / Linux, OS X), you can achieve this by using
export PATH="$HOME/.local/bin:$PATH" command.
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 installation 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.
Prerequisites and Supported Browsers
Jupyter notebook version 4.3 or later is required. To check the notebook version, run the command:
jupyter notebook --version
The latest versions of the following browsers are currently known to work:
See our documentation for additional details.
