Working with packages

Overview

All files uploaded to Anaconda.org are stored in packages. Each Anaconda.org package is visible at its own unique URL based on the name of the user who owns the package and the name of the package.

Users can create a Anaconda.org package and then upload files into it.

For more information, see package.

Note

Throughout this task, replace placeholder text like USERNAME and PACKAGENAME with the text specific to your project.

Namespaces

A namespace is the part of Anaconda.org where a user or organization may host packages. For example, the user namespace https://anaconda.org/travis contains packages that were uploaded and shared by a user named travis.

For more information, see namespace.

Labels

A label is part of the URLs on Anaconda.org where conda looks for packages.

Each file within a package may be tagged with one or more labels, or not tagged at all to accept the default label of main.

For more information, see label.

Using package managers

Anaconda.org supports two package managers, conda and PyPI. To work with conda or PyPI packages, you must use their corresponding subdomains:

  • To install conda packages from the user travis, use the repository URL https://conda.anaconda.org/travis
  • To install PyPI packages from the user travis, use the repository URL https://pypi.anaconda.org/travis

Conda packages

Uploading conda packages

This example shows how to build and upload a conda package to Anaconda.org using conda build.

Use the terminal window or an Anaconda Prompt to perform the following steps:

  1. Before you start, install anaconda-client and conda-build:

    conda install anaconda-client conda-build

  2. Choose the repository for which you would like to build the package. In this example, we use a simple public conda test package:

    git clone https://github.com/Anaconda-Platform/anaconda-client
cd anaconda-client/example-packages/conda/

    In this directory, there are two required files, meta.yaml and build.sh.

    macOS and Linux systems are Unix systems. Packages built for Unix systems require a build.sh file, packages built for Windows require a bld.bat file, and packages built for both Windows and Unix systems require both a build.sh file and a bld.bat file. All packages require a meta.yaml file.

  3. To build the package, turn off automatic Client uploading and then run the conda build command:

    conda config --set anaconda_upload no
conda build .

    All packages built in this way are placed in a subdirectory of the Anaconda conda-bld directory.

  4. You can check where the resulting file was placed with the --output option:

    conda build . --output

  5. You can upload the test package to Anaconda.org with the Anaconda upload command:

    anaconda login
anaconda upload /path/to/conda-package.tar.bz2

    Note

    Replace /path/to/ with the actual path where you stored the package.

Installing conda packages

You can install conda packages from Anaconda.org by adding channels to your conda configuration.

Use the terminal window or an Anaconda Prompt to perform the following steps:

  1. Because conda knows how to interact with Anaconda.org, specifying the channel sean translates to https://anaconda.org/sean:

    conda config --add channels sean

  2. You can now install public conda packages from Sean’s Anaconda.org account. Try installing the testci package at https://anaconda.org/sean/testci:

    conda install testci

  3. You can install a package from a channel with a token and a label:

    conda install -c https://conda.anaconda.org/t/token/channel/label/labelname packagename

    Note

    Replace token with the provided token, channel with a user channel, labelname with the label name and packagename with the package name you want to install.

PyPI packages

Uploading PyPI packages

We can test PyPI package uploading with a small public example package saved in the anaconda-client repository.

Use the terminal window or an Anaconda Prompt to perform the following steps:

  1. Begin by cloning the repository from the command line:

    git clone git@github.com:Anaconda-Platform/anaconda-client.git
cd anaconda-client/example-packages/pypi/

  2. You can now create your PyPI package with the setup.py script:

    python setup.py sdist

  3. The package has now been built as a source tarball and is ready to be uploaded:

    anaconda upload dist/*.tar.gz

    Your package is now available at http://anaconda.org/USERNAME/PACKAGE.

Installing PyPI packages

The best way to install a PyPI package is using pip. For the following command, we use the package we authored in the examples above. In your terminal window or an Anaconda Prompt, run:

pip install --extra-index-url https://pypi.anaconda.org/USERNAME/simple pypi-test-package

Installing private PyPI packages

The best way to manage access or make PyPI and other packages private is to create organizations or groups, which allow you to set separate permissions per package, notebook or environment.

You can also control access with the token system. All Anaconda.org URLs can be prefixed with /t/$TOKEN to access private packages.

In your terminal window or an Anaconda Prompt, run:

TOKEN=$(anaconda auth --create --name YOUR-TOKEN-NAME)
pip install --index-url https://pypi.anaconda.org/t/$TOKEN/USERNAME/simple-test-package

Note

Replace YOUR-TOKEN-NAME with the name of the token you created, USERNAME with your username and simple-test-package with the actual test-package name.

Uploading packages

  1. To upload package files to Anaconda.org, use the terminal window or an Anaconda Prompt and the upload command:

    anaconda login
anaconda upload PACKAGENAME

    Anaconda.org automatically detects packages and notebooks, package or notebook types, and their versions.

  2. Your package is now available at:

    https://anaconda.org/USERNAME/PACKAGENAME

  3. Your package also can be downloaded by anyone using Client from the terminal window or an Anaconda Prompt:

    anaconda download USERNAME/PACKAGENAME

Using private packages

It is no longer possible to sign up for an individual paid plan with private packages. Anyone who had private packages in the past still has the ability to have those hosted privately.

By default, all packages, notebooks, and environments uploaded to Anaconda.org are accessible to anyone who has access to the repository.

Packages uploaded to your user channel on Anaconda.org can be marked as private using the Web UI:

  1. Select the desired package.

  2. Select the Settings tab.

  3. Select Admin in the sidebar.

  4. Alternatively, you can reach this page with the following URL:

    https://anaconda.org/username/packagename/settings/admin

Note

Jupyter notebooks and conda environments can also be marked private using this procedure and URL.

Note

Other Anaconda.org users may access your private packages either with tokens or by logging in.

Private packages with tokens

Note

Replace token with the provided token, channel with a user channel, labelname with the label name, and packagename with a package name you want to install.

To make your private packages available to be accessed with tokens:

  1. First create an access token that includes the following scope for Client:

    conda:download

    Or, in the Web UI with:

    Allow private downloads from conda repositories

    The token is a random alphanumeric string and this is used to install a package or add a channel from which you want to install private packages.

  2. Using the provided token, a user channel can be added to config from the terminal window or an Anaconda Prompt with:

    conda config --add channels https://conda.anaconda.org/t/token/channel

  3. The token can also be used to install packages without first adding the channel. In the terminal window or an Anaconda Prompt, run:

    conda install -c https://conda.anaconda.org/t/token/channel packagename

    To install a package from a channel using token and label name:

    conda install -c https://conda.anaconda.org/t/token/channel/label/labelname packagename

  4. Private PyPI packages can also be installed in the Web UI:

    https://pypi.anaconda.org/t/token/channel

Private packages with login

To make your private packages available to users who have logged in:

  1. Create an organization.
  2. Create a group in that organization, which may be a read-only group.
  3. Add to the group the users that you want to grant access to.
  4. Upload the package to the organization, or transfer an existing package to the organization.

After you grant them access, other users can download and install your package using the Web UI or Client.

To download a package:

  1. In a browser, navigate to the desired channel.

  2. If the organization name is OrgName and the package name is conda-package, use these commands in the terminal window or an Anaconda Prompt:

    conda install anaconda-client
anaconda login
conda install -c OrgName conda-package

    Or instead:

    conda install anaconda-client
anaconda login
conda install -c https://conda.anaconda.org/OrgName conda-package

Removing a previous version of a package

To remove a previous version of one of your packages from Anaconda.org:

  1. Select the package name.
  2. Select the Files tab.
  3. Select the checkbox to the left of the version you want to remove.
  4. In the Actions menu, select Remove.

You may instead use the terminal window or an Anaconda Prompt:

  1. Run:

    anaconda remove USERNAME/PACKAGENAME/0.2

    Note

    Replace USERNAME with your username, PACKAGENAME with the package name and 0.2 with the desired version.

  2. You can now see the change on your profile page:

    https://anaconda.org/USERNAME/PACKAGE

Adding a collaborator to a package

You can add other users that are not part of an organization to collaborate on your packages. You will need the usernames of the other users.

  1. From your dashboard, select the package by clicking on its name.
  2. To display the package settings, select the Settings option.
  3. To display the current collaborators, select the Collaborators option.
  4. Type the username of the person you want to add as a collaborator, and then click the Add button.

Note

All collaborators are given full read/write permissions to the package, even private packages.

Removing a collaborator from a package

To revoke package access previously granted to a collaborator:

  1. From your dashboard select the package by clicking on its name.
  2. To display the package settings, select the Settings option.
  3. To display the current collaborators, select the Collaborators option.
  4. Click the red X button next to a collaborator to revoke their access.

Transferring a package to a new owner

By default, when you create or add packages, they are attached to your individual profile. You can transfer ownership to another owner account you control, such as an organization profile you manage.

To transfer a package to a new owner:

  1. From your dashboard–or the dashboard of an organization you administer–select the package for which you want to transfer ownership.

    The system displays options for that package.

  2. To display the package settings, select the Settings option.

  3. Select the Admin option.

  4. Under Transfer this package to a new owner, click the Transfer button.

  5. Select the organization name for the new owner.

  6. Click the Transfer Ownership button.

Copying a package

To copy a package from the channel conda-forge to a personal channel such as jsmith:

anaconda copy conda-forge/glueviz/0.10.4 --to-owner jsmith

conda-forge/glueviz/0.10.4 is a “spec” and can match either of two formats: user/package/version or user/package/version/filename.

Previously labels were called “channels”, and the anaconda copy command has deprecated options from-channel and to-channel that expect to operate on labels. These deprecated options should not be used. If you attempt to run anaconda copy --from-channel conda-forge --to-channel jsmith glueviz, you will receive an error that Label conda-forge does not exist.

Deleting a package

To delete a package from Anaconda.org, including all of its versions:

  1. Select the package name.
  2. Select the Settings option.
  3. In the left sidebar, select Admin.
  4. Click Delete.

You may instead use the terminal window or an Anaconda Prompt:

  1. Run:

    anaconda remove USERNAME/PACKAGENAME

  2. You can now see the change on your profile page:

    https://anaconda.org/USERNAME
