Question

我试图通过运行来安装Scikit：

pip install scikit-learn

当我运行它时，我收到此消息：

Collecting scikit-learn

    ImportError: Scientific Python (SciPy) is not installed.
    scikit-learn requires SciPy >= 0.9.
    Installation instructions are available on the scikit-learn website: http://scikit-learn.org/stable/install.html

这似乎要求我安装Scipy，但是我已经安装了Scipy，确实如果我运行

pip install scipy

我得到了

Requirement already satisfied: scipy in c:\python36\lib\site-packages
Requirement already satisfied: numpy>=1.8.2 in c:\python36\lib\site-packages (from scipy)

您的安装显示了这一点：from numpy._distributor_init import NUMPY_MKL # requires numpy+mkl ImportError: cannot import name 'NUMPY_MKL'

所以你需要做一些事情。获得正确的SciPy：http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy

获得正确的NumPy：http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy

获得正确的SciKit学习：http://www.lfd.uci.edu/~gohlke/pythonlibs/#sci-kitlearn

现在执行pip uninstall其他每个包。然后在{NumPy 1st，SciPy 2nd，然后是Ski-kitlearn最后一次提供pip install您下载的轮子上。这应该可以解决您的问题。请注意，在这些链接中，您使用cp36‑cp36m‑win32.whl或cp36‑cp36m‑win_amd64.whl下载文件，具体取决于您是否安装了32位或64位Python。

Scikit安装要求Scipy，即使它已安装
