PaddlePaddle.org requires 'print_operators_doc' command to be available in paddlepaddle/paddle:latest docker image in order to update the Operators documentation on PaddlePaddle.org website.

The command 'print_operators_doc' was removed in the following commit (line 171), which is causing Operator documentation to not get updated on PaddlePaddle.org.
