Error Saving Matplotlib Figures To Pdf: 'str' Object Has No Attribute 'decode'

I have the following script to generate a figure with matplotlib: # -*- coding: utf-8 -*- import matplotlib.pyplot as plt import numpy as np import math from matplotlib import rc

Solution 1:

The problem was solved by installing cm-super package with missing larm1200 font. Matplotlib developers, thanks for help!

Solution 2:

Using XeLaTex turned out to be a nice workaround. It has its own issues (for example, XeLaTex fails on figures with fill_between), but still it allowed to get cyrillic letters in labels.

# -*- coding: utf-8 -*-from __future__ import (absolute_import, division, print_function, unicode_literals)

import matplotlib as mpl
mpl.use("pgf")
pgf_with_custom_preamble = {
    "font.family": "serif", # use serif/main font for text elements"text.usetex": True,    # use inline math for ticks"pgf.rcfonts": False,   # don't setup fonts from rc parameters"pgf.preamble": [
         "\\usepackage{units}",         # load additional packages"\\usepackage{metalogo}",
         "\\usepackage{unicode-math}",  # unicode math setupr"\setmathfont{xits-math.otf}",
         r"\setmainfont{DejaVu Serif}", # serif font via preamble
         ]
}
mpl.rcParams.update(pgf_with_custom_preamble)
import matplotlib.pyplot as plt
import numpy as np
import math

deffigsize(wcm,hcm): plt.figure(figsize=(wcm/2.54,hcm/2.54))
figsize(13,9)

x = np.linspace(0,2*math.pi,100)
y = np.sin(x)
plt.plot(x,y,'-')
plt.xlabel(u"Ось абсцисс")
#plt.show()

plt.savefig(u"d:/fig.pdf")
