python opencv绑定包含在conda-forge上名为opencv的软件包中，或包含在pypi上的opencv-python的软件包中。在conda-forge上安装opencv将使cv2模块可用。但是，在通过conda安装此文件并根据Opencv pip install打包软件包后，pip install找不到现有的软件包。根据在setup.py中调用该程序包的方式，它要么搜索程序包但找不到它，要么找到它并与conda版本一起安装。
$ conda list | grep opencv
opencv 4.1.0 py37h5517eff_4 conda-forge
如果setup.py中的名称是opencv，它将搜索（即使已经有opencv）但找不到：
$ pip install .

如果setup.py中的名称为opencv-python，它将在第一个名称旁边安装第二个opencv，并且导入cv2模块将导致未定义的符号错误。
我如何说服pip识别opencv的conda安装？
