jupyter-conda 3.1.0

Manage your conda environments from the Jupyter Notebook and JupyterLab

jupyter_conda

Provides Conda environment and package access extension from within Jupyter Notebook and JupyterLab.

This is a fork of the Anaconda nb_conda package. The decision to fork it came due to apparently dead status of the previous package and a need to integrate it within JupyterLab.

Install

Requirements

• conda >= 4.5
• notebook >= 4.3
• JupyterLab 1.0 (for the jupyterlab extension only)

To install in the classical notebook:

conda install -c conda-forge jupyter_conda

To install in the JupyterLab:

conda install -c conda-forge jupyterlab jupyter_conda
jupyter labextension install jupyterlab_toastify jupyterlab_conda

Classical Jupyter Notebook

Conda tab in the Jupyter file browser

This extensions adds a Conda tab to the Jupyter file browser. Selecting the Conda tab will display:

• A list of the Conda environments that current exist
• The list of Conda packages available in currently configured channels (http://conda.pydata.org/docs/config.html#channel-locations-channels)
• The list of packages installed in the selected environment.

You can click on the name of an environment to select it. That will allow you to:

• see the packages installed in the environment
• install new packages from the available package list
• check for updates on selected (or all) packages
• update selected (or all) packages in the environment.

Conda in the Notebook view

This extension adds a Conda Packages item to the Kernel menu. Selecting this item displays the list of Conda packages in the environment associated with the running kernel, and the list of available packages. You can perform the same actions as in the Conda tab, but only against the current environment.

JupyterLab

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

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 2, 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

conda create -y -n jupyter_conda python jupyterlab
conda install -y -n jupyter_conda --file requirements.txt -c conda-forge
conda install -y -n jupyter_conda --file requirements_dev.txt -c conda-forge
source activate jupyter_conda
python setup.py develop
jupyter nbextension install jupyter_conda --py --sys-prefix --symlink
jupyter nbextension enable jupyter_conda --py --sys-prefix
jupyter serverextension enable jupyter_conda --py --sys-prefix

cd labextension
jupyter labextension install .

Changelog

3.1.0

• Add ability to specify kernel companions; i.e. check that if some packages are installed in a kernel, they must respect a certain version range. Companions can be specified through user settings.
• IEnvironmentManager.getPackageManager() returns always the same Conda.IPackageManager otherwise signaling package operations would have been meaningless.
• Request environment list access now whitelist=0 or 1 query arguments. If 1, the environment list is filtered to respect KernelSpecManager.whitelist. Default is 0, but it could be modified in user settings.
• Small UI tweaks

3.0.0

• Rework the server/client API to be more REST and returns 202 status for long operations
• Cache available packages list in temp directory
• Improve greatly the coverage for the server extension
• JupyterLab extension only:
  • Allow the user to change the proposed environment when creating one from scratch
  • Add signals to handle environnements and packages changes (see labextension\src\__tests__\services.spec.ts)
  • Improve the UI reactivity by using react-virtualized for the packages list
  • Improve the look and feel
• Available packages truncation has been removed.

2.5.1

• Catch SSLError when requesting channeldata.json file

2.5.0

• Export in YAML format the environment (import in the older format is still supported).
• Improve responsiveness by loading first installed packages. Then request available one.
• BUG error is prompt when an environment is deleted although everything went well
• Cache some API requests (GET environments, GET channels and GET available packages).
• Available packages are now truncated to 100.
  • Use query argument $skip to skip N first packages
  • If the list is longer than 100, a entry $next in the response is returned. This
    is the request url to use to get the next batch of packages.
• Report full error message in web browser console to ease debugging.

2.4.2

• BUG environment not shown
• BUG Installing package in develop mode fails if in user home or containing spaces
