First try the example 01.run-experiment to connect to your workspace and run a basic experiment using Azure Machine Learning Python SDK, and then 02.deploy-web-service to deploy a model as a web service.
Then move to more comprehensive examples in tutorials folder.
Important: You must select Python 3.6 as the kernel for your notebooks to use the SDK.
Note: The config.json file in this folder was created for you with details of your Azure Machine Learning service workspace. Both these notebooks use this file to connect to your workspace. You can also copy this file into other places where you have code that needs this connection.
