 >   File "usr/lib/python3.7/site-packages/cv2/__init__.py", line 56, in load_first_config
 > ImportError: OpenCV loader: missing configuration file: ['config.py']. Check OpenCV installation.

 > To fix this problem, this commit uses the newly introduced
 > <pkg>_KEEP_PY_FILES mechanism, to ensure the important config*.py
