Azure Machine Learning Tutorial (CLI / Python)

This example shows you generic AI / ML workflow through lifecycle - exploration, train, tune, and publishing - with Azure Machine Learning (AML) API.

There exist 2 options to run Azure Machine Learning (AML) API - CLI/YAML and Python SDK.

CLI / YAML (v2)

Python SDK (v2)

Python SDK (v1)

Note : When you are new to Azure Machine Learning, use v2 API.

You can also use raw REST API for invoking AML API.

How to Set up

1. Create Azure ML Workspace resource

Create new "Machine Learning" resource in Azure Portal .

Note : When you use GPU instance in Exercise04, please specify the location (region) for machine learning resource, in which you can run GPU virtual machine.
See Exercise04 for details.

2. Create Virtual Machine for running AML API

We run code with TensorFlow in Exercise03.
Here I use Ubuntu Server 20.04 LTS in Microsoft Azure for client, in which Python 3.8 is already installed.

  • Create Ubuntu Server 20.04 LTS virtual machine resource in Azure Portal.

  • Please make sure that Python 3.8 is installed on Ubuntu.

# Check version
python3 -V
### # Set python3.8 as default python command (Here I assume /usr/bin/python3.8)
### sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.8 1
  • Install and upgrade pip3 as follows.
sudo apt-get update
sudo apt-get install -y python3-pip
sudo -H pip3 install --upgrade pip
  • In this tutorial, we run all exercises in IPython notebook.
    Install Jupyter as follows.
pip3 install jupyter
  • Install the required packages for Exercise03. (Use "tensorflow-gpu" instead, when using GPU VM.)
pip3 install matplotlib tensorflow==2.10.0

Note : When you use Azure Machine Learning compute instance, install packages in terminal.

Choose the following settings (3A, 3B, or 3C), depending on which API (CLI/YAML or Python SDK) you use.

3A. Set up for Azure ML CLI v2

For running AML CLI/YAML, install Azure Machine Learning CLI extension version 2.0 or above as follows.

  • Install Azure CLI (version 2.15 or above) as follows. (See here for details.)
curl -sL https://aka.ms/InstallAzureCLIDeb | sudo bash

Note : To see the installed Azure CLI version, run az --version.

  • Install AML CLI extension as follows.
az extension add --name ml --version 2.12.1

3B. Set up for Azure ML Python SDK v2

For running AML Python SDK v2, install Python SDK version 2 as follows.

pip3 install azure-ai-ml==1.2.0 azure-identity==1.12.0

3C. Set up for Azure ML Python SDK v1

For running AML Python SDK v1, install Python SDK version 1 and depending other packages as follows.

Azure Machine Learning (AML) provides core package (azureml-core) and as well as extension packages. Depending on tasks, you should install addtional extensions. (For instance, if you want to run automated machine learning in AML, you should install automl extension package (azureml-train-automl) as well.)

In this tutorial, we use AML interactive widget's extension (azureml_widgets) used in Exercise 06, and AML train core extension (azureml-train) used in Exercise 07, and pipeline extensions (azureml-pipeline-core and azureml-pipeline-steps) used in Exercise 09.
Install the required Python packages as follows.

# Install AML SDK Core
pip3 install azureml-core

# Install AML interactive widgets extension
pip3 install azureml-widgets

# Install AML train extension (including HyperDrive package)
pip3 install azureml-train

# Install AML dataset extension
pip3 install azureml-dataset-runtime

# Install AML pipeline extension
pip3 install azureml-pipeline-core azureml-pipeline-steps

Note : AML widget's extension is installed as Jupyter notebook extension.
Run jupyter nbextension list to see the installed Jupyter extensions.

4. Clone this repo

Clone this repository in your working environment.

git clone https://github.com/tsmatz/azureml-tutorial

5. Start Jupyter Notebook

  • Start Jupyter notebook as follows. (Please re-login to take effect for "jupyter" path.)
    This will show the access url in console, such as http://localhost:8888/tree?token=xxxxxxxxxx.
    (The default port is 8888.)
jupyter notebook

  • Connect to Ubuntu server with SSH tunnel (port forwarding) from your working desktop in order to access notebook URL.
    For instance, the following is the SSH tunnel setting on "PuTTY" terminal client in Windows. (You can use ssh -L option in Mac OS.)
    SSH Tunnel settings with putty

  • Copy the notebook URL (http://localhost:8888/?token=...) in the console output (see above) and open this address with your web browser.
