我无法在我的MacOS塞拉上安装opencv (或) cv2。
我试过pip install opencv,它说:
Could not find a version that satisfies the requirement opencv
当我使用brew install opencv时,它给了我一个信息:
opencv2 is already installed but not linked so run this command:
export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH
但是即使它
我有一个将Python混合在一起的OpenCV项目,在切换到OpenCV 2.1之后,我对C代码的调用不再起作用,这可能是因为OpenCV不再使用OpenCV绑定。
在Python中,我使用以下原型调用一个C函数:
int fast_support_transform(CvMat * I, CvMat * N,...);
现在,我得到以下错误:
TypeError: in method 'fast_support_transform', argument 1 of type 'CvMat *'
C代码来自我创建的一个库,它使用SWIG生成Python接口。我不确
长话短说。我从复制了这段代码(虽然不是真正的导入,但我还是提到了)
import cv2
from matplotlib import pyplot as plt
# Opening image
img = cv2.imread("image.jpg")
# OpenCV opens images as BRG
# but we want it as RGB and
# we also need a grayscale
# version
img_gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
img_rgb =
我正在尝试在CentOS6上编译和安装OpenCV3(目标是Python3.4)。当我执行cmake时,我设置了以下选项。
BUILD_opencv_python3=ON
BUILD_opencv_videoio=OFF(turned this off because I am not using the video modules and this throws some errors while compiling)
PYTHON3_EXECUTABLE=/usr/local/python/bin/python3.4
PYTHON3_INCLUDE_DIR=/usr/local/pytho
此程序目前无法工作。
#!/usr/bin/env python3
import numpy as np
import cv2
from matplotlib import pyplot as plt
img = cv2.imread('trial.jpg',0)
plt.imshow(img, cmap = 'gray', interpolation = 'bicubic')
plt.xticks([]), plt.yticks([]) # to hide tick values on X and Y axis
plt.show()
我犯了
首先,非常感谢您的阅读。 几天前,我在Ubuntu18.04桌面系统上安装了Python3 (3.6.9)和opencv 3.4.10。在一些编译问题(与python3无关)后,我需要将opencv降级到3.4.0,所以我使用sudo make uninstall命令删除了opencv 3.4.10,并测试它是否被卸载,就像我尝试在python中导入它一样,我得到了以下错误: libopencv_hfs.so.3.4: cannot open shared object file: no such file or directory 我以为安装3.4.0版本就可以解决这个问题,但是现在它已经
