Hi,
My system is a MacBook Pro (i9 processor) with macOS Mojave Version 10.14.3, I have installed Matplotlib version 3.0.2 and what
I want to do is use an external TeX renderer but I always get: FileNotFoundError: [Errno 2] No such file or directory: 'latex': ?latex?.
I get the aforementioned message, for example, trying to execute the following code:
"""
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 have installed MacTex and also MiKTek with their installers and Ghostscript with Home-brew. I use Spyder installed with Conda.
Using Mathtext everything is alright.
In which directory Matplotlib expect to find the directory ?latex??
Thank you all
Stefano

I use Windows, so my answer may not be relevant, but MiKTeX installation
does not necessarily update your path,? so check that, it may be as
simple as that. What happens if you launch latex in a terminal?
(In Win10 latex.exe is where you put it, e.g.,? in
C:\MiKTeX\miktex\bin\x64\)
Good luck

I think Jerzy is correct, we are expecting `latex` to be on the path.
Does `latex` work at the shell in the same context as you are running
python?
