windows下解决numpy, scipy等库安装失败的方法

如果pip安装scipy库失败，可以参考以下方法：

scipy官方上提供了这样的方法：

Windows packages

Windows does not have any package manager analogous to that in Linux, so installing one of the scientific Python distributions mentioned above is preferred. However, if that is not an option, Christoph Gohlke provides pre-built
Windows installers for many Python packages, including all of the core SciPy stack, which work extremely well.

如果无法pip安装scipy等第三方库，可以去上面这个网址下载.whl文件，下载到本地之后

python -m pip install ***.whl

记得一定要下载和自己使用的python版本和操作系统对应的whl文件。
