【问题描述】：

我想使用ximgproc的一些功能，所以我卸载了opencv-python并重新安装了opencv-contrib-python

(venv) C:\Users\Administrator\PycharmProjects\eps>pip uninstall opencv-contrib-python opencv-python
Skipping opencv-contrib-python as it is not installed.

Proceed (y/n)? y

但是，我仍然无法导入 ximgproc。有什么我忘记了吗？

【解决方案1】：

你能检查一下你用pip list 安装了哪些包吗？即使你卸载了 opencv-python，你也需要卸载 opencv-python-headless, opencv-contrib-python-headless 包。正如@skvark 所说

永远不要同时安装这两个包

【讨论】：

oauthlib 3.1.0 open3d 0.10.0.1 opencv-contrib-python 4.5.1.48 opencv-python 4.5.1.48 opt-einsum 3.2.0 打包 20.4 pandocfilters 1.4.2
我裁剪了 O 部分，将尝试仅安装 contrib
很奇怪，即使您之前已经卸载过，也无法卸载。再次尝试卸载opencv-python 4.5.1.48，否则可以尝试手动删除：stackoverflow.com/a/14572899/14950238

【解决方案2】：

分别安装 opencv 和 opencv-contrib 模块。
标准桌面环境的命令：

$ pip install opencv-python opencv-contrib-python

【讨论】：

你不应该同时安装这两个包。只有后者会被实际安装，它会覆盖第一个。它还会使您的环境不一致，因为pip 会显示已安装opencv-python，但实际上它已被opencv-contrib-python 覆盖。
