Manual install opencv and tensorflow wheel packages

[ByteBrigand]

The correct versions of opencv and tensorflow are not being found by pip, need to specify wheel URL manually. URL found at https://pypi.org/project/tensorflow/1.15.5/#files and https://pypi.org/project/opencv-python/4.5.2.52/#files

Thanks, it helps me a lot. For whom encounters the same problem as me when running pip install -e ., this is the best solution.

Here is the detailed error message:

File "setup.py", line 445, in _classify_installed_files_override
      raise Exception("Not found: '%s'" % relpath_re)
  Exception: Not found: 'python/cv2/py.typed'
