Windows10 64位 Python2.7 Matplotlib安装

为了安装Matplotlib 百度了一大堆，也下载了一大堆安装包，结果还是报错ImportError: DLL load failed: %1 不是有效的 Win32 应用程序。

后来直接从官网看怎么安装http://matplotlib.org/users/installing.html

For standard Python installations you will also need to install compatible versions of setuptools, numpy, python-dateutil, pytz, pyparsing, and cycler in addition to matplotlib.

然后发现好像可以直接用Powershell利用内置的pip（python包管理工具，详情可参见https://pip.pypa.io/en/stable/）

首先是更新一下pip （确保pip能使用）

然后将setuptools, numpy, python-dateutil, pytz, pyparsing, cycler,matplotlib分别代替最后的pip并运行

网上找的测试代码：

from mpl_toolkits.mplot3d import axes3d
import matplotlib.pyplot as plt
from matplotlib import cm

fig = plt.figure()
ax = fig.gca(projection='3d')
X, Y, Z = axes3d.get_test_data(0.05)
ax.plot_surface(X, Y, Z, rstride=8, cstride=8, alpha=0.3)
cset = ax.contour(X, Y, Z, zdir='z', offset=-100, cmap=cm.coolwarm)
cset = ax.contour(X, Y, Z, zdir='x', offset=-40, cmap=cm.coolwarm)
cset = ax.contour(X, Y, Z, zdir='y', offset=40, cmap=cm.coolwarm)

ax.set_xlabel('X')
ax.set_xlim(-40, 40)
ax.set_ylabel('Y')
ax.set_ylim(-40, 40)
ax.set_zlabel('Z')
ax.set_zlim(-100, 100)

plt.show()

得到下图的话，恭喜你，ok了
