title: OpenCV-CUDA Win10. Python Module Not Found on Import
body: <p>So, I have been working on getting opencv with nvidia gpu support for a few days now and can't get python to import cv2 (importing precompiled opencv-python works as expected).  Out of frustration I just deleted then unzipped the opencv_contrib_master and, to my surprise, a few new lines popped up in CMake:</p>
  
  <p>Under Ungrouped Entries:</p>
  
  <pre><code>BUILD_OPENCV_CUDA
  </code></pre>
  
  <p>Under Python 3:</p>
  
  <pre><code>install path:                C:/ProgramData/Anaconda3/Lib/site-packages/cv2/python-3.7
  </code></pre>
  
  <p>Under OpenCV:</p>
  
  <pre><code>OPENCV_PYTHON3_VERSION 
  </code></pre>
  
  <p>Great. Progress. But now a new foe appears: </p>
  
  <pre><code>CMake Warning at cmake/OpenCVGenSetupVars.cmake:54 (message):
    CONFIGURATION IS NOT SUPPORTED: validate setupvars script in install
    directory
  Call Stack (most recent call first):
    CMakeLists.txt:967 (include)
  </code></pre>
  
  <p>The above error is mentioned <a href="https://stackoverflow.com/questions/56606865/opencv-cmake-warning-meanings-cmakelists-txt1066-include/56682558">here</a> and states the error is related to the python configuration. I thought the PY3 config looked ok:</p>
  
  <pre><code>PYTHON3_EXECUTABLE                C:/ProgramData/Anaconda3/python.exe
  PYTHON3_INCLUDE_DIR               C:/ProgramData/Anaconda3/include
  PYTHON3_INCLUDE_DIR2
  PYTHON3_LIBRARY                   C:/ProgramData/Anaconda3/libs/python37.lib
  PYTHON3_LIBRARY_DEBUG             PYTHON_DEBUG_LIBRARY-NOTFOUND
  PYTHON3_NUMPY_INCLUDE_DIRS        C:/ProgramData/Anaconda3/Lib/site-packages/numpy/core/include
  PYTHON3_PACKAGE_PATH              C:/ProgramData/Anaconda3/Lib/site-packages
  </code></pre>
  
  <p>Edit 10: on a subsequent installation I saw Cmake enters numpy library from User/Roaming instead of ProgramData/Anaconda3. I do not know if the difference affects build success.</p>
  
  <p>I noticed these were missing (not sure if it matters):</p>
  
  <pre><code>CUDA_nvToolsExt_LIBRARY-NOTFOUND
  CUDA_nvcuvenc_LIBRARY-NOTFOUND
  CUDA_nvcuvid_LIBRARY-NOTFOUND
  </code></pre>
  
  <p>Along with BLAS/LAPLACK/EIGEN. I still am not unclear whether these are necessary for python handle. </p>
  
  <p>Using GTX 1080, so I only kept gpu arch version 6.1. Omitting other versions cut build time from 2hr15min to ~30min:</p>
  
  <pre><code>Pascal (CUDA 8 and later)
  SM60 or SM_60, compute_60 – Quadro GP100, Tesla P100, DGX-1 (Generic Pascal)
  SM61 or SM_61, compute_61 – GTX 1080, GTX 1070, GTX
