它给出了这个错误：

error: /tmp/build/80754af9/opencv_1512687413662/work/modules/highgui/src/window.cpp:593: 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 cvNamedWindow
我使用conda安装了这个软件包，因此无法理解如何对其进行更改。
答案 0 :(得分：0)
似乎是你的opencv的问题，从错误我的假设是你从源代码构建它
l建议卸载当前的opencv并通过pip pip install opencv-python
