[TOPI] conv2d schedule code

[mingwayzhang]

We find a potential issue in the following line of the code:

https://github.com/dmlc/tvm/blob/master/topi/python/topi/cuda/conv2d_direct.py#L93

Line 93: ryo, ryi = cfg['tile_rx'].apply(s, OL, ry)

Should tile_rx be tile_ry?

Good catch. This is a bug when KH != KW.
We have to fix the schedule code and update records in TopHub. Other users should also update their local autotvm records.

[mingwayzhang]

could I submit a patch to fix this?

Thanks! Please also update the latest version of records here https://github.com/uwsampl/tvm-distro/tree/master/tophub

[mingwayzhang]

Do you mean I need to exchange the value of tile_rx and tile_ry in all these files? Please clarify. Thanks.

1. Exchange tile_rx and tile_ry in tvm-distro/tophub/cuda_v0.04.log, and save it to tvm-distro/tophub/cuda_v0.05.log
2. Update the version number in https://github.com/dmlc/tvm/blob/83591aa5a139108976baf3febc7263c6f069ce9c/python/tvm/autotvm/tophub.py#L42
   to "v0.05"
