Gator

The Mamba Navigator, a Web UI for managing conda environments

Provides Conda/Mamba environment and package management as a standalone application or as extension for JupyterLab.

Install

Requirements

• conda >= 4.7.12 or mamba >= 1.0 (mamba 2.x also works)
• JupyterLab >= 4.0 (for the JupyterLab extension only)

This extension will use mamba instead of conda if it finds it.

To install in the JupyterLab:

mamba install -c conda-forge jupyterlab mamba_gator

Optionally, you could install jupyterlab-tour to add a help tour for the conda packages manager.

JupyterLab

This extension adds a new entry Conda Packages Manager in the Settings menu.

The first time, it can take quite some time to build the available packages list. But once it is obtained, it will be cached and updated to the background to have a smoother user experience.

Gator (Mamba navigator)

This project contains a standalone navigator application sharing much of the code of the JupyterLab extension.

Creating New Environments

There are three ways to create an environment:

• Create a new environment Use the New Environment button at the top of the page, and select Python 3, or R to create a base environment with the corresponding packages. Note that if you want to run a Jupyter python kernel in the new environment, you must also install the ipykernel package in the environment.

• Clone an existing environment Click the clone button next to an environment in the list, and enter the desired name of the new environment.

• Import an exported environment from a YAML file

Development

To setup a development environment follow our Contributing Guide.

If you would like to try a pre-release version:

conda create -c conda-forge -y -n gator python=3.14 nodejs jupyterlab=4.0
conda activate gator
pip install git+https://github.com/mamba-org/gator.git
jupyter lab

Acknowledgements

This work started as a fork by @fcollonval of the Anaconda nb_conda package to add JupyterLab support.

Then with the mamba initiative pushed by QuantStack it made sense to move the project in the mamba-org organization.
