运行下列代码：

import matplotlib.pyplot as plt

edu = [0.2515,0.3724,0.3336,0.0368,0.0057]
labels = ['中专','大专','本科','硕士','其他']

plt.pie(x=edu,labels=labels,autopct='%.1f%%')

plt.show()

会出现：

RuntimeWarning: Glyph 20013 missing from current font.   font.set_text(s, 0.0, flags=flags)

这是matplotlib绘制的图里面不能正常显示中文，提示警告
matplotlib绘图中文警告

【解决方法】：

import matplotlib.pyplot as plt

edu = [0.2515,0.3724,0.3336,0.0368,0.0057]
labels = ['中专','大专','本科','硕士','其他']

plt.pie(x=edu,labels=labels,autopct='%.1f%%')
plt.rcParams['font.sans-serif']=['SimHei']#显示中文标签
#plt.rcParams['font.sans-serif']=['Microsoft YaHei'] #写这个也可以显示中文标签

plt.show()
