Chinese characteristic cannot display normally 
any solutions? thanks 
I solve this problem.
matplotlib in datalore doesn’t support chinese characteristic, becaues ‘matplotlib.font_manager.FontProperties’ don’t have corresponding style. I need to download by myself and set it properly.
from pylab import *
import matplotlib .pyplot as plt
import numpy as np
myfont = matplotlib.font_manager.FontProperties(fname=r"./STFANGSO.ttf") # !!!
t = np.arange(-5*np.pi, 5*np.pi, 0.001)
y = np.sin(t)/t
my_post = plt.plot(t, y)
plt.title(u'matplotlib中文显示测试——Zhengyuan Lan',fontproperties=myfont)
plt.xlabel(u'这里是X坐标',fontproperties=myfont)
plt.ylabel(u'这里是Y坐标',fontproperties=myfont)
plt.show()
