CMake Error: The source directory "/home/michael/opencv-3.1.0/release/CMAKE_INSTALL_PREFIX=/home/michael/opencv-3.1.0" does not exist. 碰到这个问题基本上无解,找了好多地方都没有说这个问题。 而碰巧的是,最后深度一下,把-D后面的空格去掉果然可以。 cmake

cv2.imread()接受图像路径并不会报错(即使它不存在),显示图像时发现路径无效,然后返回None。 当尝试传递无效的图片(即None图像)到另一个OpenCV函数中,Python + OpenCV会报错该图像没有任何宽度,高度或深度信息等: >>> import cv2 >>> path = "path/to/image/that/does/not/exist.png" >>> image = cv2....

更新动态链接库:在终端中输入sudo ldconfig以更新动态链接库。 验证安装:在终端中输入 python3,然后在Python交互式环境中输入 import cv2,如果没有错误,则说明安装成功。 以上就是如何在Linux系统上安装 OpenCV 的步骤。希望您能够成功安装!
