Thank you for your contribution! @daixinghome
It seems that the lint check fails. Would you mind following the https://github.com/open-mmlab/mmpose/blob/master/.github/CONTRIBUTING.md to setup the pre-commit?

I'm sorry for the mistakes. Now it's ok with my pre-commit's checking.

Well, it seems that there is no testcase for ignore_too_much parameter in master version. I add the testing now.

This PR looks good to me in general. And I have tested the accuracy, which is good also.
One minor comment is to unify the style of code commenting.
