[GitHub] [incubator-mxnet] igolan opened a new issue #16188:
symbol.contrib.cond does not support some built-in operators
igolan opened a new issue #16188: symbol.contrib.cond does not support some built-in operators
URL: https://github.com/apache/incubator-mxnet/issues/16188
## Description
``symbol.contrib.cond`` operator does not support the build-in operators ``round``, ``floor`` and ``ceil`` (and probably some more).

## Steps to reproduce
1. Run the code above. hybrid_forward has few lines with comment if it's working or not (uncomment lines to see more examples)
## What have you tried to solve it?
N/A
Might be related to #12154 , #11641 , #16182 and #16187 . I keep those issues separate because I'm not sure the cause is the same.
