windows环境下 pip 安装 seaborn 失败?

matploatlib 包很强大，但对于需要快速做一些基础图形的朋友来说 界面似乎有点简陋，基于matploatlib 开发seaborn 包 显得更好看一些，这点我很喜欢

这次安装并不是那么顺利，我想一定有不少朋友会也会遇到，为了避免大家再绕弯路，特写了这片日志。

seaborn 依赖 matploatlib、numpy、 scripy、pandas

我的python版本是2.7 64bit ，系统win7 64bit

 由于默认python exe包并没有增加环境变量到系统中去，我一般是到python 目录中执行

cd C:\Python27

前两个依赖好说， 一条命令即可；

python.exe -m pip install matploatlib 

python.exe -m pip install numpy

python.exe -m pip install seaborn 

seaborn  会自动安装依赖 scripy, 但是pip 库中好像并没有所需要的dll库 导致报错,不得不说pip这方面 做的还是弱了点...

        import numpy.core.numeric as _nx
      File "C:\Python27\lib\site-packages\numpy\core\__init__.py", line 14, in <
module>
        from . import multiarray
    ImportError: DLL load failed: %1 不是有效的 Win32 应用程序。

这时候我们需要做的是手动下载whl文件 然后用pip 安装.

http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy

下载对应版本的，pytho2还是python3 64bit还是32bit 一定要对上(以当前安装的python版本为准)。

下载下来的whl我放进了python目录 然后执行下列操作。

C:\Python27>python.exe -m pip install scipy-0.18.1-cp27-cp27m-win_amd64.whl
Processing c:\python27\scipy-0.18.1-cp27-cp27m-win_amd64.whl

OK, 这样我们就安装完成了.....  希望以后大家遇到类似的问题 可以举一反三。

当然 Anaconda 也是一个不错的集体环境， 科学运算方面的包比较齐全,不喜欢麻烦的朋友也可以去下载安装。
