LuckyPigeon edited a comment on issue #12781: Fixed issue #12745 URL: https://github.com/apache/incubator-mxnet/pull/12781#issuecomment-465454078 @aaronmarkham I'm not sure what went wrong while building docs. I've tried built the code of this pull request on ubuntu 1804 and the `$` sign can be removed successfully. So that must be some other thing went wrong while building the docs. Can you recommend some people for help solving the problem? Thanks!
