icemelon9 commented on issue #4769: [TOPI] Remove cpp upsampling and resize op URL: https://github.com/apache/incubator-tvm/pull/4769#issuecomment-577910874 I agree with @masahi. During the work of #4644, I found a few inconsistency between cpp and python topi implementation. Even for some simple schedule like injective, python version is better than cpp version, and has already overwritten the cpp implementation. I feel that keeping both cpp and python implementation for topi is a bit confusing, even that one op may only exist in cpp or python. Given that most of people now contribute to topi python, it makes sense that we only maintain the python version. In response to @tqchen, op compute could be stable, but the schedule might not be. Even op compute doesn't change over the time, we can still improve its schedule for better performance. It's easier to do so in python than in cpp.
