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
