python - 如何在 Windows 上安装 opencv_contrib？

Question

我想在 python 中使用 function createFisherFaceRecognizer()，但是当我写下 model = cv2.createFisherFaceRecognizer() 或 cv2.face.createFisherFaceRecognizer ()会发生错误:

Traceback (most recent call last): File "C:\Users\Administrator\Desktop\My projects\test\RecognizeMe.py", line 5, in model = cv2.face.createFisherFaceRecognizer() AttributeError: 'module' object has no attribute 'face'

引用了网上的方法，发现应该安装opencv_contrib，但是在配置opencv的时候卡住了 使用 CMake。错误:

CMake Error at cmake/OpenCVUtils.cmake:895 (file): file DOWNLOAD HASH mismatch

for file: [E:/opencv-3.1.0/sources/opencv-3.1.0/3rdparty/ffmpeg/downloads/35fe6ccdda6d7a04e9056b0d73b98e76/opencv_ffmpeg_64.dll]

如何解决这个问题？谢谢您的回答!

嗯，各种方法都试过了，用CMAKE和VS2013都不行。但是我找到了一个包 opencv_contrib_python-3.2.0.7-cp27-none-win32.whl，只需 pip install 就可以了。这是一个下载链接:Download opencv_contrib_python.whl
