报错：Font family [‘sans-serif’] not found. Falling back to DejaVu Sans Mac
解决办法：换自带的字体，不用SimHei
from matplotlib.font_manager import FontManager fm = FontManager() mat_fonts = set(f.name for f in fm.ttflist) print(mat_fonts)
plt.rcParams['font.sans-serif'] = ['Songti SC'] # 用来正常显示中文标签 #plt.rcParams['font.family'] = ['sans-serif'] #图片显示中文 plt.rcParams['axes.unicode_minus'] =False #减号unicode编码
