I fix the problem in this way:

  • I installed opencv using brew

brew install opencv

  • I installed opencv for python

pip install opencv-python

  • I removed (bad) numpy library

sudo rm -rf /usr/local/lib/python3.7/site-packages/numpy

  • I linked numpy library with working library

sudo ln -s /usr/local/Cellar/numpy/1.17.1/lib/python3.7/site-packages/numpy /usr/local/lib/python3.7/site-packages/numpy
