Not sure if this is related with the fact that we switched to https://github.com/PaddlePaddle/mirrors-yapf.

I tried pre-commit install and pre-commit autoupdate, and they don't fix the following error:

yi@WangYis-iMac:~/work/paddle/paddle/majel (remove_unnecessary_test_output)*$ git commit -a -m 'Remove unnecesssary test outputs'
