在Windows 10上安装scikitlearn

Question

我正在尝试在我的Windows10机器上安装scikitlearn，它使用python3。在

我已经安装了Python3并开始工作。事实上，我还安装了其他一些库，比如pandas、matplotlib、beauthulsoup4。在

我的第一次尝试是一个简单的pip install scikit-learn。我得到一个错误提示它缺少依赖项scipy，我认为{}可以为我处理，但是不管怎样。接下来我做了pip install scipy，得到了一大堆错误。看来我又失去了一堆依赖关系。在

下面是pip install scipy的输出。有没有一种简单的方法可以在Windows上安装scikit-learn和scipy，而不必手动处理所有依赖项？在

    Note: if you need reliable uninstall behavior, then install
    with pip instead of using `setup.py install`:

    - `pip install .`       (from a git repo or downloaded source
                            release)
    - `pip install scipy`   (last SciPy release on PyPI)
