Tfx: Airflow initidb errors

[johnomahen79]

Started with json errors and that changed when i updated Wekzeug but now i get this error:
No module named 'werkzeug.wrappers.json'
Told me to upgrade Flask and Jinja .....so is there a list of all correct compatible versions on the github site that I missed or ? thanks

I suggest is to pin the version of airflow, Werkzueg and Flask.

See https://github.com/tensorflow/tfx/commit/711a9d899324de4b7207c04ecd905872bdcd2e9e for an example.

Please let me know if it works.

This is an issue with Airflow 1.13.0 which didn't correctly pin the version of Flask: https://issues.apache.org/jira/projects/AIRFLOW/issues/AIRFLOW-4900

If you've already installed airflow 1.13, you should be able to resolve this with
pip install --upgrade Flask

No module named 'werkzeug.wrappers.json'

Did you try: pip install -U Werkzeug or try installing 0.14

[zhitaoli]

I would suggest try pinning related softwares to a known good version: pip
install apache-airflow==1.10.3 Flask==1.0.4 Werkzeug==0.14.1
