@amogkam Where can i find the build error log?

You can see it by clicking on the bug icon on the flaky test tracker https://flakey-tests.ray.io/

There are many errors in the build log, but none of them related to this PR. P.S. many failed builds have no output.

No output has been received in the last 10m0s, this potentially indicates a stalled build or something wrong with the build itself.
Check the details on how to adjust your build configuration on: https://docs.travis-ci.com/user/common-build-problems/#Build-times-out-because-no-output-was-received
The build has been terminated

@amogkam I found some worker crashes in this build log: https://travis-ci.com/github/ray-project/ray/jobs/524307882

I am not sure if it is the root cause of the failure. Some other errors are caused by missing psutil.

The build log also shows the redis failure:

@amogkam @zhe-thoughts The event module is disabled by default, it is only enabled in the test_event.py. I need more clues about the build failure.

[fyrestone]

@amogkam I noticed that the mac wheel build still fails after the revert. I think it's better to show the error details in the build log, so that we can fix it quickly. Currently, I don't know which error caused the build to fail.

[amogkam]

You're right @fyrestone this isn't causing the failures. We can merge back in.

Thanks.
