How do I call Cognitive Services from Azure Machine Learning?

Microsoft has a multitude of tools and libraries for developers who want to utilize machine learning, from the Cognitive Services which perform facial detection, emotion recognition, text analytics, and more with a simple API call, to Azure Machine Learning which allows you to build your own custom ML models, to the CNTK which is our open-sourced deep-learning toolkit.  Sometimes you may want to use this technology together.  In a recent project, I wanted to call the Cognitive Services Face APIs from inside of an AzureML model that I was building.  Currently, the best way to do this is using an “Execute Python Script” module to call out to a Cognitive Services web service.  There is a sample that you can leverage to help you get started at https://gallery.cortanaintelligence.com/Experiment/Calling-web-service-from-Python-1.
