Setting up a default project environment (AEN 4.2.1)

AEN includes a full installation of the Anaconda Python distribution—along with several additional packages—located within the root conda environment in /opt/wakari/anaconda. A copy of this environment is created for each new AEN Project.

To configure a different set of packages than the default:

1. Create a new conda environment in the /opt/wakari/anaconda/envs/default directory.

   EXAMPLE: Using a Python 3.4 base environment, run:

   sudo -u $AEN_SRVC_ACCT /opt/wakari/anaconda/bin/conda \
       create -p /opt/wakari/anaconda/envs/default python=3.4
   

2. Use conda to install any additional packages into the environment.

3. After the environment is created, clone it to ensure that it works correctly:

   sudo -u $AEN_SRVC_ACCT /opt/wakari/anaconda/bin/conda \
       create -p /opt/wakari/testenv --clone /opt/wakari/anaconda/envs/default
   sudo -u $AEN_SRVC_ACCT rm -rf /opt/wakari/testenv
   

The default project environment is cloned into the project workspace the first time the project is started.

Converting an existing project

1. Run the following command to clone the environment:

   sudo -u $AEN_SRVC_ACCT /opt/wakari/anaconda/bin/conda \
       create -n /projects/owner/project/envs/<ENV_NAME> \
       --clone /opt/wakari/anaconda/envs/default
   

   NOTE: Replace /projects/owner/project/envs/<ENV_NAME> with the path to the new environment you would like to create within the project.

2. Open the Compute Resource Configuration application for your project and set the project environment path there as well.
