   @leezu I think I have to give up on this issue or find a different approach. What I tried was the following:
   - update python to 3.8 
   - update some dependencies that needed updating in order to work with python 3.8
   - Fix some linting issues that needed fixing because of the updated linter dependencies.
   Then I did the following :
   (1) Kick off a build and observe the failing tests
   (2) remove the failing test in order to isolate the test failures
   I was expecting that the build would pass at some point. However I noticed that even after multiple iterations, I couldn't isolate  the test failures. Every time I kicked off a build, I would find another set of failing tests, sometimes in a different sub-build. 
   Hmm.. I'm not sure how to proceed at this point. If you have some suggestions, I'd be happy try it. Otherwise I think I have to give up on this. Maybe the issue needs to be split up into multiple tasks such as "make unix-cpu succeed with python 3.8", "make unix-gpu succeed with python 3.8", etc.
