Hello,

I'm having big trouble using cv2.detectMultiScale running on my computer. It takes a huge amount of time to detect.

The time for finding the detection areas is at least several minutes, and sometimes I get the results until one hour later.

I'm using opencv 3.2.0 and python 3.6.0 on macOS Sierra 10.12.3.

Which is really weird is that the detection is very fast (<100ms) when launching exactly the same script from a macOS El Capitan 10.11.6 with opencv 3.1.0_3 and python 3.5.1.

Have you an idea of what can cause such a thing?

Thank you in advance for your help
