Undefined symbol: cvWaitKey when import pyyolo

[TuanHAnhVN]

Hi Mr. Park. When running your example.py file, i met this error "Undefined symbol: cvWaitKey" (because of pyyolo import) As i know, pyyolo source uses function incorrect. How to repair it? Thank so much!

Install OpenCV for python. sudo apt-get install python-opencv

Oh no. I had installed before i posted this issue. My OpenCV version: 3.3.0. waitKey instead of cvWaitKey?

[digitalbrain79]

I'm sorry. It only tested with OpenCV 2.4.

How do I repair it? Can you support for me? Thanks1

I am also stuck with this problem. How do i proceed?

@christian-ek I think you should change version of OpenCV or @thomaspark-pkj update code! ^^
