Installation$ sudo apt-get install python3-pyqt5 $ sudo apt-get install pyqt5-dev-tools $ sudo apt-get install qttools5-dev-tools $ pip3 install pyqt5Configuring to run from terminal $ qtchooser -run-tool=designer -qt=5

https://stackoverflow.com/questions/48333362/opencv-assert-false-in-file-qasciikey-cpp I was wrong. You said it run fine at first... Then I search for qasciikey.cpp, find it is a Qt file. Did you compile OpenCV with flag WITH_QT=ON? Maybe change flag to WITH_QT=OFF, this is not use Qt, will work.

1) PPA 추가$ sudo add-apt-repository ppa:jonathonf/python-3.6 2) 업데이트 및 설치$ sudo apt-get update $ sudo apt-get install python3.6
