如何处理解决 Anaconda 中的环境安装问题？

Question

我正在尝试使用 Anaconda 提示符安装 OpenCV。我已经尝试过 anaconda 和 conda-forge 版本。

使用article's提到的命令后：-

conda install -c menpo opencv

我收到以下消息：-

Collecting package metadata (current_repodata.json): done

Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

有人可以帮忙吗？我想在 Anaconda 的 spyder 中运行 opencv

看起来 hdf5 与您的安装冲突。 您应该尝试使用 conda 创建一个新的虚拟环境，并在安装 openCV 之前从该虚拟环境中删除 hdf5。这样你就安全了。

你可以这样做：

conda create --name test_env
conda activate test_env
conda remove hdf5
conda install -c conda-forge opencv
