Python: Unable to Render Tex in Matplotlib

Question

I recently upgraded my laptop to Snow Leopard, updated TeX to Version 3.1415926 (TeX Live 2011/MacPorts 2011_5), and installed Python 2.7.3. After all these installs, I ran macport selfupdate and macport upgrade outdated. However, now when I try to use TeX in matplotlib, I receive the following:

LaTeX was not able to process the following string:'lp'
Here is the full report generated by LaTeX:

Similar to this previous question , I tried setting the path in my python code via:

os.environ['PATH'] = os.environ['PATH'] + ':/opt/local/bin/latex'

since which latex yielded /opt/local/bin/latex . However, that didn't work, with the same error message. I also tried the path to tex, as well as the example from the previous question. No change.

I then tried to force possibly missing packages via:

matplotlib.rcParams['text.latex.preamble']=[r"\usepackage{amsmath}"]

however, that also did not work.

The only way I can get my plots to work is to say rc('text', usetex=False) , which is not ideal. Any help would be much appreciated.

Answer 1

On an Ubunutu 14.04 machine the combination of answers from above worked. I sudo apt-get install the dvipng , texlive-latex-extra , and texlive-fonts-recommended packages and that did the trick:

$ sudo apt-get install dvipng texlive-latex-extra texlive-fonts-recommended 

Edit: As of Matplotlib 3.2.1, you now also need the package cm-super (see https://github.com/matplotlib/matplotlib/issues/16911 )

$ sudo apt-get install dvipng texlive-latex-extra texlive-fonts-recommended cm-super

Answer 2

The error message says you're missing the type1cm package. It seems that MacPorts includes it as part of texlive-latex-extra .

Answer 3

我必须将cm-super包安装在 ubuntu 衍生版本（从 Ubuntu 18.04 派生的jupyter/minimal-notebook ） $ sudo apt-get install cm-super

Answer 5

除了dvipng texlive-latex-extra texlive-fonts-recommended ， Ubuntu 20.04还需要cm-super 。

Answer 6

On Manjaro (Arch), I only needed to install texlive-latexextra , which contains the type1cm.sty file.

pacman -S texlive-latexextra

The packages texlive-bin and texlive-core were already installed on my computer and would likely also be required.
