Can you review this please, @fchollet?

[fchollet]

Thanks for the PR.

[yanboliang]

I fixed the bad indentation, can anyone trigger the build again? Thanks.

[caisq]

@yanboliang Done

[yanboliang]

@caisq I fixed the bad indentation again, can you re-trigger it? Thanks. BTW, do you know how I can trigger python lint checker locally before I submit the PR?

[caisq]

@yanboliang With the necessary dependencies installed, you should be able to run it with this script (from the root directory of the repo): https://github.com/tensorflow/tensorflow/blob/master/tensorflow/tools/ci_build/ci_sanity.sh

[yanboliang]

@caisq Great. I just run that script and verified this PR can pass sanity check locally. Can you trigger this test again? I'm sorry to bother you again. Thanks.

Gently ping @fchollet @caisq . Would mind to have a look at this? Thanks.

I think @fchollet has implicitly approved this PR when he applied the "awaiting test then merge" tag. I've applied the "ready to pull" tag, which should have triggered the merging process. let me try it again.

[yanboliang]

@caisq Thanks!
