@juncaipeng hard_swish in oneDNN is not merged yet. Usually oneDNN team have one update every two weeks.

[lidanqing-vv]

oneDNN team said hard swish is already merged on gitlab (internal oneDNN repo) , so it is matter of when they have next public release. We are still asking.

[jczaja]

oneDNN team just released hard-swish . So now we just need to modify our PR with hard-swish support to use newer oneDNN and test it. Hopefully we will be doing this within next few days.
