我正在运行命令“pip3 install scikit-learn”，命令提示符吐出以下错误：

我知道我的 numpy+MKL 和 Scipy 以及我的 C++ Redistributable 都是最新的。知道是什么原因造成的吗？

Duplicate of Error while trying to install sklearn from Pycharm | arrayobject.h cannot be absolute -- "Python 3.6（最新版本）尚不支持，您可以考虑降级（实际重新安装）到 Python 3.5 .. 显然，sklearn 在支持 Python 3.6 时几乎没有问题那一刻。”

【解决方案1】：

从这里安装它 http://www.lfd.uci.edu/~gohlke/pythonlibs/ 。如果你使用python 3.6和win64下载scikit_umfpack‑0.2.3‑cp36‑cp36m‑win_amd64.whl这个。

【解决方案2】：

你能用Anaconda试试吗？ https://www.continuum.io/downloads#windows 安装 anaconda 后，您可以使用 conda 创建一个虚拟环境： conda create -n myenv python=3.5

之后，您将激活 evn source activate myenv (myenv)$ conda install scikit-learn

这对我有用
