media-libs/opencv should add PYTHON_COMPAT python3_6. The following binary opencv distribution is compatible with python 3.6, so the gentoo ebuild should also be: https://pypi.python.org/pypi/opencv-python Thanks!
Have you tested with Python 3.6?
I haven't tested with python 3.6 yet. Unfortunately I can't build opencv-3.3 in the first place (i.e. independently of enabling python3_6): > In file included from /var/tmp/portage/media-libs/opencv-3.3.0-r1/work/opencv-3.3.0/modules/dnn/misc/tensorflow/attr_value.pb.cc:5:0: > /var/tmp/portage/media-libs/opencv-3.3.0-r1/work/opencv-3.3.0/modules/dnn/misc/tensorflow/attr_value.pb.h:12:2: error: #error This file was generated by a newer version of protoc which is > #error This file was generated by a newer version of protoc which is > ^~~~~ > /var/tmp/portage/media-libs/opencv-3.3.0-r1/work/opencv-3.3.0/modules/dnn/misc/tensorflow/attr_value.pb.h:13:2: error: #error incompatible with your Protocol Buffer headers.

Yes there is another 5 bugs for it. We are working on repair ;) Thank you..
Thanks for your work on it! With #631418 fixed I tried compiling with PYTHON_COMPAT python3_6. Everything seems to work.
