Copying a Conda Environment to Another Region

In this tutorial, you install a conda environment in a notebook session. Then you perform the necessary steps to install the same conda environment in a second notebook session hosted in a different region.

Key tasks include how to:

  • Create two buckets in two different regions in your tenancy.
  • Register each bucket with a notebook session in their region.
  • Install a conda environment in the first notebook session.
  • Publish the conda environment. (Make the conda environment ready to be installed from any notebook session that has access to the environment.)
  • From the first notebook session, add the published conda environment to a bucket of the same region.
  • Copy the published conda environment from one bucket to another.
  • In a notebook session in the second region, install the conda environment, by using the second bucket.

Before You Begin

To successfully perform this tutorial, you must have the following:

Requirements

  • A paid Oracle Cloud Infrastructure (OCI) account, or a new account with Oracle Cloud promotions. See Request and Manage Free Oracle Cloud Promotions.

  • A MacOS, Linux, or Windows computer.
  • Data Science tutorial:
    • Go through all the steps in Manually Configuring a Data Science Tenancy and create two notebook sessions with the following properties:
      • Name the compartment for your work data-science-work.
      • Create notebook sessions in two regions:
        • To change your region, in the Console's top navigation bar, select your region and then click the name of a new region. For example, switch from US West (Phoenix) to US East (Ashburn).
        • Name your projects and notebook sessions:
          • In <region-1>: Initial Project and my-first-notebook-session
          • In <region-2>: Second Project and my-second-notebook-session

1. Create Buckets

Create two buckets to store conda environments of my-first-notebook-session and my-second-notebook-session.

Create Two Buckets

Create a bucket in <region-1> and another one in <region-2>.

  1. Open the navigation menu and select Storage. Under Object Storage & Archive Storage, click Buckets.
  2. In the left navigation, under List Scope, select the data-science-work compartment.
  3. In the top navigation bar, select <region-1>. For example, US West (Phoenix).
  4. SelectCreate Bucket.
  5. Fill in the following information:
    • Name: bucket-1
    • Leave the default value for other fields:
      • Default Storage Tier: Standard
      • Encryption: Encrypt using Oracle managed keys
  6. SelectCreate.
  7. In the list of buckets, ensure that bucket-1 has a Private Visibility:
    Buckets are private, unless you change their visibility after you create them.
  8. In the top navigation bar, select <region-1>, and from the list of regions, select <region-2>. For example, switch to US East (Ashburn).
  9. Repeat the previous steps to create bucket-2 in <region-2>.
You have successfully created two private buckets in two different regions.
Get the Tenancy Namespace

Every tenancy has a unique system-generated immutable Object Storage namespace name. This namespace name is the same in all regions. In this step, you copy this namespace name and later use it to register your buckets with your notebook sessions.

  1. Open the navigation menu and select Storage. Under Object Storage & Archive Storage, click Buckets.
  2. In the left navigation, under List Scope, select the data-science-work compartment.
  3. In the top navigation bar, select <region-2>. For example, US East (Ashburn).
  4. In the list of buckets, select bucket-2.
  5. Copy the Namespace in a notepad: <tenancy-namespace>.
    Note

    Namespace names are unique within a tenancy. If bucket-1 and bucket-2 are in different tenancies, then copy the namespace names for both buckets.

2. Publish a Conda Environment in Region 1

Install a conda environment in your notebook session. Then from the notebook session, publish the conda environment to a bucket.

Register bucket-1

Register bucket-1 with my-first-notebook-session.

  1. In the Console's top navigation bar, select <region-1>.
  2. In the left navigation, under List Scope, select the data-science-work compartment.
  3. Open the navigation menu and select Analytics & AI. Under Machine Learning, select Data Science.
  4. Under the list of projects, select Initial Project.
  5. Selectmy-first-notebook-session and then click Open.
  6. Enter your credentials to access the JupyterLab interactive notebook.
  7. In the UI, if you don't have a tab called Launcher, click File, and then New Launcher.
  8. In the Launcher, under Other, select the Terminal icon to start a new terminal session.
  9. In the terminal, enter the following command.

    Replace <tenancy-namespace> with the information that you gathered in the Create Buckets section.

    odsc conda init -b bucket-1 -n <tenancy-namespace>
  10. Go to File, and then select Open from Path.... In the Open Path field, enter /conda.
  11. To confirm that the preceding command registered your bucket with your notebook, under the conda folder, click config.yaml and find bucket-1 and your namespace in the following block of code: 
    auth_mode: resource_principal
bucket_info:
  name: bucket-1
  namespace: <tenancy-namespace>
pack_prefix: conda_environments
Install a Conda Environment

Install a prebuilt Data Science conda environment in your notebook session.

  1. In my-first-notebook-session, click File and then New Launcher.
  2. In the Launcher, under Extensions, select the Environment Explorer icon.
  3. In the list of Conda Environments, expand ONNX 1.10 for CPU on Python 3.9.
  4. Copy the command to install ONNX 1.10 for CPU on Python 3.9, and paste it into a terminal: 
    odsc conda install -s onnx110_p39_cpu_v1
    • For version number, keep the default displayed value, such as 1.0.

    • Destination Bucket: bucket-2
    • Destination Object Name: To preserve the directory structure, keep the default string.
    • Leave the default value for other fields:
      • Destination Storage Tier: (leave blank)
      • Overwrite Rule: Overwrite destination object
  8. SelectCopy Object.
  9. If you get a warning section for not having the correct IAM policy statements, select Try to add statements. 
    Allow service objectstorage-<region-1> to manage object-family in compartment data-science-work

    If you don't get this warning message, then skip the next three steps.

  10. In the Add IAM Policy panel, keep the defaults.
    • Name: console-iam-policy-<timestamp>
    • Description: IAM policy statements created by the Console on <timestamp>
    • Add policy statement to the root compartment: not selected

  11. (Optional) To allow objects in other regions to be copied to your compartment, you can add the following policy to the Policy Statements section in the Add IAM Policy panel
    Note

    To allow objects in other regions to be copied to your compartment, for each region, in a new line, add the following policy to the Policy Statements section in the Add IAM Policy panel:

You have successfully copied a conda environment from one region to another, and used it in a notebook session in the second region.

To learn more about conda environments, in your notebook session:

  • In the Launcher, under Extenstions, select the Notebook Explorer icon. Select ONNX Integration with the Accelerated Data Science (ADS) SDK, select Open, and explore the examples.
  • Go to Environment Explorer and install other prebuilt Data Science conda environments, not mentioned in this tutorial.
