You should consider upgrading via the 'pip install --upgrade pip' command.

我用过 sudo -H ，所以我不明白为什么会这样。我的 Python 安装

readlink -f $(which python) | xargs -I % sh -c 'echo -n "%: "; % -V'

它对我有用 this tutorial.

我使用的是 Anaconda 2.7 版本并创建了一个虚拟环境(可以随意使用 py3 & python=3.5):

conda create --name py2 python=2.7 anaconda

不要忘记在安装前激活它(然后使用!):

source activate py2

我建议升级 scikit-learn 和 libgcc:

conda upgrade scikit-learn libgcc

然后按照链接的教程进行操作。

自从您 5 个月前询问以来，我认为这已经发生了很大变化，但我希望它能帮助那些偶然发现这篇文章的人。在您的情况下，我认为这确实是 miniconda 和系统 python 发行版之间的冲突。
