Hi all, I am one of the maintainer for MXNet Scala package. Currently I am building up a hash-check system on the generated API through C. The PR is in this URL: https://github.com/apache/incubator-mxnet/pull/11239 A file named FILEHASH will be added to the Scala that created the MD5 string of the generated API document. It will check the signature of all the operators during Scala CI testing. The reason I am doing this is to make sure Scala developers will always be reminded if there is an operator name/argument changes happened in different PRs. More detailed info explained in here: https://cwiki.apache.org/confluence/display/MXNET/MXNet+Scala+API+Usability+Improvement
Pros: This method will always help us keep backwards compatibility of operators for Scala Cons: Require update on the FILEHASH with new contents when there is an operator change. Developers who changed the operator should `make scalapkg` to update that file. Please leave any thoughts you may have for this design and feel free to review the code. Thanks, Qing
