【问题描述】：

我通过此页面安装了安装 sklearn 的先决条件：https://scikit-learn.org/stable/install.html 并且一切安装正常。但是，当我尝试导入 sklearn 时，我收到错误（如下）。有什么想法吗？

安装：

# pip3 install -U scikit-learn[alldeps]==0.22
Looking in indexes: http://devpi.na-pytools.tds.local/na/dev/+simple/
Requirement already up-to-date: scikit-learn[alldeps]==0.22 in /usr/local/lib/python3.5/site-packages (0.22)
Requirement already satisfied, skipping upgrade: scipy>=0.17.0 in /usr/local/lib/python3.5/site-packages (from scikit-learn[alldeps]==0.22) (1.4.1)
Requirement already satisfied, skipping upgrade: joblib>=0.11 in /usr/local/lib/python3.5/site-packages (from scikit-learn[alldeps]==0.22) (0.14.0)
Requirement already satisfied, skipping upgrade: numpy>=1.11.0 in /usr/local/lib/python3.5/site-packages (from scikit-learn[alldeps]==0.22) (1.18.1)

错误：

【参考方案1】：

我最终用 make altinstall 和 virtualenv 安装了 python 3.6.8，解决了这个问题。
