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
