cv2.error when using demo.py

[yenanfei]

When I run demo.py I met this error.Can you give me some advices to deal with it?
python3 bin/demo.py test.jpg --lift_model sample/gen_epoch_500.npz --model pose_iter_440000.caffemodel --proto2d openpose_pose_coco.prototxt

You have to re-build the openCV3.4 with python3.6 by yourself.
Please do not forget this.
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

for example, (sorry Japanese)

Thank you for your example.I have solved this problem.But there's another one.Do you know how to solve it?

During handling of the above exception, another exception occurred:

How did you solve the previous problem?

@singhketan @yenanfei you can also install OpenCV 3.4 for Python 3.6 from a pip wheel: https://www.lfd.uci.edu/~gohlke/pythonlibs/#opencv
