python怎么导入sklearn_Python Sklearn导入

我遇到了导入sklearn的问题。在

我已经通过pip安装了这个包,但是python不能导入这个库。我在Windows10环境中使用Python2.7。在from sklearn.tree import DecisionTreeClassifier, export_graphviz

我得到的错误是:

^{pr2}$

我读过有人通过安装SciPy(SciPy-0.19.1)找到解决方案。焦油gz)但是当我尝试通过pip安装时,提示符会返回以下消息:C:\Python27\Scripts>pip install scipy

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)
