Question

我的代码：

import cv2
import numpy
import matplotlib

img=cv2.imread('square1.png')
cv2.imshow('FRAME',img)
cv2.waitKey()

错误讯息：

Traceback (most recent call last):
  File "/Users/tusharsharma/Desktop/image project/test1.py", line 5, in <module> cv2.imshow('FRAME',img)
cv2.error: /Users/travis/build/skvark/opencv-python/opencv/modules/highgui/src/window.cpp:583:
error: (-2) The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. 
If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, 
then re-run cmake or configure script in function cvShowImage

操作系统是macOS Sierra。我使用自制软件为Python 3安装了OpenCV。

Answer 2

主要问题是配置OpenCv2的构建，确保输入python库和Header文件的正确部分例如，以下命令适用于OpenCv for Python 3.6.1 cmake -D CMAKE_BUILD_TYPE=RELEASE \ -D PYTHON3_EXECUTABLE=$(which python3) \ -D PYTHON3_INCLUDE_DIR=$(python3 -c "from distutils.sysconfig import get_python_inc; print(get_python_inc())") \ -D PYTHON3_LIBRARY=/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/config-3.4m/libpython3.4.dylib \ -D PYTHON3_LIBRARIES=/Library/Frameworks/Frameworks/Python.framework/Versions/3.4/bin \ -D PYTHON3_INCLUDE_DIR=/Library/Frameworks1/Frameworks/Python.framework/Versions/3.4/Headers \ -D PYTHON3_PACKAGES_PATH=$(python3 -c "from distutils.sysconfig import get_python_lib; print(get_python_lib())") \ -D INSTALL_C_EXAMPLES=OFF -D INSTALL_PYTHON_EXAMPLES=ON \ -D BUILD_EXAMPLES=ON \ -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules ..
