Python Opencv imshow错误

Question

cmake-d cmake_build_type=release-d cmake_install_prefix=/usr/local-d with_tbb=on-d build_new_python_support=on-d with_v4l=on-d install_c_examples=on-d install_python_examples=on-d build_examples=on-d with_qt=on-d with_gtk=on-d with_opengl=on。

如果我尝试python：

导入cv2

打印(CV2.版本）

3.2.0

import cv2
image = cv2.imread("/home/reigin/Pictures/games.jpg")
gray_image = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
cv2.imshow("Over the Clouds", image)
cv2.imshow("Over the Clouds - gray", gray_image)
cv2.waitKey(0)
cv2.destroyAllWindows()

cv2.imshow("Over the Clouds", image)

您可能使用了不支持GTK的pip opencv-python。python绑定必须来自OpenCV的构建。

检查/usr/local/lib/python2.7/site-packages/文件夹，并确保您有一个编译和安装opencv的cv2.so文件，并且您没有在dist-packages中使用来自PIP的opencv-python的包。

参见此处:http://www.pyimagesearch.com/2015/06/22/install-opencv-3-0-and-python-2-7-on-ubuntu/

这里是我的Cmake行,为安装做准备：

cmake-d cmake_build_type=release-d cmake_install_prefix=/usr/local-d with_tbb=on-d with_gtk=on-d with_v4l=on-d with_opengl=on-d with_cublas=on-dwith_qt=off-dcuda_nvcc_flags=“-d_force_inlines”.

请注意，这假设您已经通过sudo apt-get install libgtk2.0-dev安装了适当的libgtk。

这才是CMake要吐槽的：

--GUI：

--gtkglext:YES(ver 1.2.0)

--OpenGL支持：是(/usr/lib/x86_64-linux-gnu/libglu.so/usr/lib/x86_64-linux-gnu/libgl.so)

--VTK支持：是（版本6.2.0)
