各位好！在issues里看了半天了，看的我有点晕。我也遇到了这个报错error: (-212:Parsing error) Unsupported activation: mish in function 'ReadDarknetFromCfgStream'，这个问题到底被解决了吗？使用哪个版本能解决这个报错呢？

ZijianWang-ZW commented 4 years ago

It seems that the problem has not been solved yet.

AlexeyAB commented 4 years ago

There is no problem if you use OpenCV-master-branch

ramdhan1989 commented 4 years ago

I Got problem building from master branch using windows. So, for temporary solution replace mish to leaky activation in cfg file
