junrushao1994 commented on issue #16188: symbol.contrib.cond does not support some built-in operators URL: https://github.com/apache/incubator-mxnet/issues/16188#issuecomment-532883670 Just digged a while with @zheng-da. This bug should be related to inconsistency between operator implementation (F.round does not require original input when doing backward) and cached op (in which there are pieces of code that assume original input exists). We have a workaround in the post above that forces the input to exist, but this is definitely a bug somewhere unrelated to control flow operator itself. Could someone help us with the fix?
