There are a number of ways to learn machine learning on Google Cloud Platform (GCP) but my favourite is using Qwik labs. What's great about it is that each lab has a preconfigured environment that includes all the essential permissions and setup.
I've tried using the cloud services of Open Shift, Amazon Web Services (AWS), Microsoft Azure, IBM Watson and GCP and I found that getting the service working with the right options is a major source of confusion. I found AWS to be the hardest - their fine granularity of rules and privileges felt tedious. Qwik labs include a user login with the right permissions to complete the lab step-by-step. This means that I could realistically commit an hour to learning the basics of the Machine learning.
