翻译I have the following problem and I am totally new to matplotlib and python: To produce high qualitiy plots for my thesis I want to use matplotlib and I want to use the latex commands for the axes etc. When I try the following example (from http://matplotlib.org/users/usetex.html#usetex-tutorial):
import numpy as np import matplotlib.pyplot as plt # Example data t = np.arange(0.0, 1.0 + 0.01, 0.01) s = np.cos(4 * np.pi * t) + 2 plt.rc('text', usetex=True) plt.rc('font', family='serif') plt.plot(t, s) plt.xlabel(r'\textbf{time} (s)') plt.ylabel(r'\textit{voltage} (mV)',fontsize=16) plt.title(r"\TeX\ is Number " r"$\displaystyle\sum_{n=1}^\infty\frac{-e^{i\pi}}{2^n}$!", fontsize=16, color='gray') # Make room for the ridiculously large title. plt.subplots_adjust(top=0.8) plt.savefig('tex_demo') plt.show()I get the following message:

sudo apt-get install python3 sudo apt-get install python-matplotlib sudo apt-get build-dep python-matplotlibI am using texmaker and thought this could be the problem; so I did the following:
sudo aptitude install texlive-fonts-recommended texlive-fonts-extraIf I try any other plots including latex commands I get similar error messages, or plots without any lables for the axes.
