Error in train model

[yassirez-znafry]

I'm having trouble completing the getting_started example (getting_started.md) as the pipeline stops on the train (takes too long ≈ 60 min on train model job). Here are the last logs before canceling automatically (the file contains the entire logs:

This the how I workaround, downgrade your pip version:

I've updated the Train step to use pip 20.2.4 as a temporary fix - https://github.com/MicrosoftDocs/pipelines-azureml/blob/master/models/diabetes/config/train-conda.yml. The step still fails for me in the pipeline but it is successful in the Azure Machine Learning environment. I'm working on getting more help on this from the product team.
