Developing a project¶
To enable Anaconda Enterprise to manage the dependencies for your project—so you can run it and deploy it—you need to configure the following settings for each project you create or upload:
- Include all the packages used by the project (e.g., conda, pip, system).
- Create a custom Conda environment.
- Specify the deployment command required to run the project.
- Specify environment variables to use in editor sessions and deployments.
All dependencies are tracked in a project’s
While there are various ways to modify this file—using the user interface or
a command-line interface—any changes to a project’s configuration will
persist for future project sessions and deployments, regardless of the method
This is different than using
conda install to add a package using the
conda environment during a session, as that method impacts the project
temporarily, during the current session only.
Jupyter Notebook supports
anaconda-project commands only.
You’ll need to run these commands in a terminal.
To open a terminal window within a Jupyter Notebook editor session:
Adding packages to a project¶
Anaconda Enterprise offers several ways to add packages to a project, so you can choose the method you prefer:
- In a JupyterLab editing session, click the Project tab on the far left and click the Edit pencil icon in the PACKAGES field. Add your packages and click Save.
In a terminal run
anaconda-project add-packagesfollowed by the package names and optionally the versions.
anaconda-project add-packages hvplot pandas=0.25
The command may take a moment to run as it collects the dependencies and downloads the packages. The packages will be visible in the project’s
anaconda-project.yml file. If this file is already open, close it and reopen it to see your changes.
To install packages from a specific channel:
anaconda-project add-packages -c conda-forge tranquilizer
anaconda-project commands must be run from the
This is the default environment when using the Jupyter Notebook terminal. For
JupyterLab, it will be the first terminal on left. If your terminal prompt is not
(lab_launch), you can activate it with the command
conda activate lab_launch.
channel_alias for conda in Anaconda Enterprise is configured to point to the internal package repository, which means that short channel names will refer to channels in the internal package repository.
To use packages from an external or online package repository, you will need to specify the full channel URL such as
anaconda-project add-packages bokeh -c https://conda.anaconda.org/pyviz in a command or in
channel_alias can be customized by an administrator, which affects all sessions and deployments.
If you are working in an air-gapped environment (without internet access), your Administrator will need to mirror the packages into your organization’s internal package repository for you to be able to access them.
To install pip packages:¶
List the packages in the
pip: section of
anaconda-project.yml. For example:
packages: - six>=1.4.0 - gunicorn==19.1.0 - pip: - python-mimeparse - falcon==1.0.0
After editing the
anaconda-project.yml file to include the pip packages you want to install, run the
anaconda-project prepare command to install the packages.
To install system packages:¶
In a terminal, run
sudo yum install followed by the package name.
sudo yum install sqlite
Any system packages you install from the command line are available during the current session only. If you want them to persist, add them to the project’s
anaconda-project.yml file. The system package must be available in an Anaconda Enterprise channel for it to be installed correctly via the
Custom project environment¶
Each project only supports the use of a single environment.
For the standard template projects the Conda environments have been pre-built as a bootstrap to reduce initialization time when additional packages are added as described above. However, you may wish to create a custom environment specification.
You may use either of these methods to specify the environment for a project:
In a JupyterLab editing session, click the Project tab on the far left and click the plus sign to the right of the ENVIRONMENTS field. Choose whether you want to Prepare all environments or Add environments.
Select an environment and then select Run, Check or Edit. Running an environment opens a terminal window with that environment active.
When creating an environment, you may choose to inherit from an existing environment, and choose the environment’s supported platforms, its channels, and its packages.
You can use the terminal and command line. For example, to create an environment called
new_envwith notebook, pandas, and bokeh:
anaconda-project add-env-spec --name new_env anaconda-project add-packages --env-spec new_env notebook pandas=0.25 panel=0.6
Remove the original environment that corresponds to the template you chose when you initially created the project. For example, to remove the Python 3.6 environment:
anaconda-project remove-env-spec anaconda50_py36
You must include the
notebook package for the environment to edit and run notebooks in either the Jupyter Notebook or JupyterLab editors.
anaconda-project command ensures that the environment will prepare correctly when the session is restarted. For more information about
anaconda-project commands type
To verify whether an environment has been initialized for a Notebook session:
- Within the Notebook session, open a terminal window:
- Run the following commands to list the contents of the parent directory:
If the environment is being initialized, you’ll see a file named
preparing. When the environment has finished initializing, it will be replaced by a file named
If you need to troubleshoot session startup, you can use a terminal to view the session startup logs. When session startup begins, the output of the
anaconda-project prepare command is written to
/opt/continuum/preparing, and when the command completes, the log is moved to
Adding deployment commands to a project¶
You can use Anaconda Enterprise to deploy projects containing notebooks, Bokeh applications, and generic scripts or web frameworks. Before you can deploy a project, it needs to have an appropriate deployment command associated with it.
Each of the following methods can be used to add a deployment command in the project’s config file
- In a JupyterLab editing session, click the Project tab on the far left and click the plus sign to the right of the COMMANDS field. Add information about the command and click Save.
This method is available within the JupyterLab editor only, so you’ll need to set that as your default editor—in the project’s Settings—and restart the project session to see this option in the user interface. The two methods described below do not show notifications in the user interface.
- Use the command line interface:
anaconda-project add-command --type notebook default data-science-notebook.ipynb
The following are example deployment commands you can use:
For a Notebook:
commands: default: notebook: your-notebook.ipynb
For a project with a Bokeh (version 0.12) app defined in a
commands: default: bokeh_app: . supports_http_options: True
For a Panel dashboard (panel must be installed in your project):
commands: default: unix: panel serve script-or-notebook-file supports_http_options: True
For a generic script or web framework, including Python or R:
commands: default: unix: bash run.sh supports_http_options: true
commands: default: unix: python your-script.py supports_http_options: true
commands: default: unix: Rscript your-script.R supports_http_options: true
For deployment commands that can handle
anaconda-project-- arguments (like Panel)
supports_http_options: True must be added to the command.
To validate your
anaconda-project.yml and verify your project will deploy successfully:
- Within the Notebook session, open a terminal window:
Run the following command, replacing
anaconda44_py35with the name of your environment, if it’s different:
anaconda-project prepare --env-spec anaconda44_py35
If the environment includes everything needed to deploy the project, you’ll see a message like the following:
Otherwise, any errors preventing a successful deployment will be identified.
If you want to test the deployment immediately after preparing the environment, run the following command instead:
anaconda-project run <command-name>
If there are any errors preventing a successful deployment, they will be displayed in the terminal.
You can add environment variables that will be set when you run notebooks in an editor session and at the start of a deployment command.
- In a JupyterLab editing session, click the Project tab on the far left and click the
+button next to VARIABLES. Provide the name, description and default value of all variables you require.
You can use the terminal and command line. For example, to add an environment variable that sets
anaconda-project add-variable --default hello MY_VAR
