How to deploy an AutoML model to an online endpoint

[!INCLUDE cli v2]

In this article, you'll learn how to deploy an AutoML-trained machine learning model to an online (real-time inference) endpoint. Automated machine learning, also referred to as automated ML or AutoML, is the process of automating the time-consuming, iterative tasks of developing a machine learning model. For more, see What is automated machine learning (AutoML)?.

In this article you'll know how to deploy AutoML trained machine learning model to online endpoints using:

• Azure Machine Learning studio
• Azure Machine Learning CLI (v2))

Prerequisites

An AutoML-trained machine learning model. For more, see Tutorial: Train a classification model with no-code AutoML in the Azure Machine Learning studio or Tutorial: Forecast demand with automated machine learning.

Deploy from Azure Machine Learning studio and no code

Deploying an AutoML-trained model from the Automated ML page is a no-code experience. That is, you don't need to prepare a scoring script and environment, both are auto generated.

1. Go to the Automated ML page in the studio

2. Select your experiment and run

3. Choose the Models tab

4. Select the model you want to deploy

5. Once you select a model, the Deploy button will light up with a drop-down menu

6. Select Deploy to real-time endpoint option

   The system will generate the Model and Environment needed for the deployment.

7. Complete the wizard to deploy the model to an online endpoint

Deploy manually from the studio or command line

If you wish to have more control over the deployment, you can download the training artifacts and deploy them.

To download the components you'll need for deployment:

1. Go to your Automated ML experiment and run in your machine learning workspace
2. Choose the Models tab
3. Select the model you wish to use. Once you select a model, the Download button will become enabled
4. Choose Download

:::image type="content" source="media/how-to-deploy-automl-endpoint/download-model.png" lightbox="media/how-to-deploy-automl-endpoint/download-model.png" alt-text="Screenshot showing the selection of the model and download button":::

You'll receive a zip file containing:

• A conda environment specification file named conda_env_<VERSION>.yml
• A Python scoring file named scoring_file_<VERSION>.py
• The model itself, in a Python .pkl file named model.pkl

To deploy using these files, you can use either the studio or the Azure CLI.

Studio

1. Go to the Models page in Azure Machine Learning studio

2. Select + Register Model option

3. Register the model you downloaded from Automated ML run

4. Go to Environments page, select Custom environment, and select + Create option to create an environment for your deployment. Use the downloaded conda yaml to create a custom environment

5. Select the model, and from the Deploy drop-down option, select Deploy to real-time endpoint

6. Complete all the steps in wizard to create an online endpoint and deployment

CLI

[!INCLUDE cli v2]

Configure the CLI

To create a deployment from the CLI, you'll need the Azure CLI with the ML v2 extension. Run the following command to confirm that you've both:

:::code language="azurecli" source="~/azureml-examples-main/cli/misc.sh" id="az_version":::

If you receive an error message or you don't see Extensions: ml in the response, follow the steps at Install and set up the CLI (v2).

Sign in:

:::code language="azurecli" source="~/azureml-examples-main/cli/misc.sh" id="az_login":::

If you've access to multiple Azure subscriptions, you can set your active subscription:

:::code language="azurecli" source="~/azureml-examples-main/cli/misc.sh" id="az_account_set":::

Set the default resource group and workspace to where you wish to create the deployment:

:::code language="azurecli" source="~/azureml-examples-main/cli/setup.sh" id="az_configure_defaults":::

Put the scoring file in its own directory

Create a directory called src/ and place the scoring file you downloaded into it. This directory is uploaded to Azure and contains all the source code necessary to do inference. For an AutoML model, there's just the single scoring file.

Create the endpoint and deployment yaml file

To create an online endpoint from the command line, you'll need to create an endpoint.yml and a deployment.yml file. The following code, taken from the Azure Machine Learning Examples repo shows the endpoints/online/managed/sample/, which captures all the required inputs:

automl_endpoint.yml

::: code language="yaml" source="~/azureml-examples-main/cli/endpoints/online/managed/sample/endpoint.yml" :::

automl_deployment.yml

::: code language="yaml" source="~/azureml-examples-main/cli/endpoints/online/managed/sample/blue-deployment.yml" :::

You'll need to modify this file to use the files you downloaded from the AutoML Models page.

1. Create a file automl_endpoint.yml and automl_deployment.yml and paste the contents of the above example.

2. Change the value of the name of the endpoint. The endpoint name needs to be unique within the Azure region. The name for an endpoint must start with an upper- or lowercase letter and only consist of '-'s and alphanumeric characters.

3. In the automl_deployment file, change the value of the keys at the following paths:

   Path	Change to
   model:path	The path to the model.pkl file you downloaded.
   code_configuration:code:path	The directory in which you placed the scoring file.
   code_configuration:scoring_script	The name of the Python scoring file (scoring_file_<VERSION>.py).
   environment:conda_file	A file URL for the downloaded conda environment file (conda_env_<VERSION>.yml).

   [!NOTE] For a full description of the YAML, see Online endpoint YAML reference.

4. From the command line, run:

   [!INCLUDE cli v2]

   az ml online-endpoint create -f automl_endpoint.yml
   az ml online-deployment create -f automl_deployment.yml
   

---

After you create a deployment, you can score it as described in Invoke the endpoint to score data by using your model.
