“TypeError: a bytes-like object is required, not 'str'” in savefig when using usetex:true

When using savefig with text.usetex:true in matplotlib, I get TypeError: a bytes-like object is required, not 'str'



EDIT: The solution for me was to upgrade matplotlib from 2.1.0 to 3.0.2



I can save to a png format with usetex:true but not pdf. I can save to pdf with usetex:false. Here is the minimal code required to produce the error:



import matplotlib as mpl
mpl.use('pdf')
import matplotlib.pyplot as plt

mpl.rcParams['text.usetex'] = True
fig, axes = plt.subplots(1, 1)
fig.savefig('test.pdf')


I have Miktex 2.9 installed, and also the most recent versions of dvipng and Ghostscript as mentionned here: https://matplotlib.org/tutorials/text/usetex.html?highlight=usetex



I added the following to my path:



C:Program Filesgsgs9.26bin
C:Program FilesMiKTeX 2.9miktexbinx64


I'm using Windows 10, Python 3.6.3 and matplotlib 2.1.0.



I also tried deleting my .matplotlib/tex.cache directory, with no success.

  • Did you try to use savefig(b'test.pdf')?

    – Bakuriu
    Nov 28 '18 at 18:58











  • I tested the code with matplotlib 2.0.2, 2.2.2, 3.0.1 with python 3.6 on windows and miktex 2.9 and it works fine. I do not currently have any 2.1.0 environment for testing though, but maybe it's still a problem that can be resolved by updating matplotlib.

  • Did you try to use savefig(b'test.pdf')?

  • I tested the code with matplotlib 2.0.2, 2.2.2, 3.0.1 with python 3.6 on windows and miktex 2.9 and it works fine. I do not currently have any 2.1.0 environment for testing though, but maybe it's still a problem that can be resolved by updating matplotlib.
