ここにも同様の質問がありますが、この問題をすべて解決するものはありません。私は場合は、Windows上でJupyterノートブックやアナコンダのPythonを使用してmatplotlibのウェブサイトでdemo codeをコピーアンドペースト：RuntimeError：LaTeXは次の文字列を処理できませんでした：r'lb '
"""
Demo of TeX rendering.
You can use TeX to render all of your matplotlib text if the rc
parameter text.usetex is set. This works currently on the agg and ps
backends, and requires that you have tex and the other dependencies
described at http://matplotlib.org/users/usetex.html
properly installed on your system. The first time you run a script
you will see a lot of output from tex and associated tools. The next
time, the run may be silent, as a lot of the information is cached in
~/.tex.cache

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()
私は次のエラーを取得する（注：同様の問題はPython 3.xまたは2.7倍を実行しているかどうか）。

これは、WindowsまたはLinuxで動作するiPythonノートブックで発生しました。私が使用してbashシェルでこれを実行したときただし、：

このエラーは、Windowsシェルに表示されませんでしたか、PowerShellとしか登場：

私はstderr出力で、この小さな宝石を持ってGNU/Linuxのbashシェルで。 pylatexや他のPythonラテックスツールをインストールしてもLaTeX自体は実際にインストールされず、インストールされていないというエラーが表示されないことがあります。うまくいけば、これは他人を助けるでしょう。私は（Ubuntuの上sudo apt install latexを使用して）ラテックスをインストールしたら

をこれは、同じものに問題を軽減するようですPython: Unable to Render Tex in Matplotlibとして実行してsudo apt install dvipng texlive-latex-extra texlive-fonts-recommendedを実行してください（Ubuntuでも同様ですが、Macに追加パッケージをインストールする場合は同様の効果があります）。
残念ながら、私はWindows（特にWindowsの下のJupyter Notebook）でこの問題を解決する方法を見つけ出していません。Windowsを使用している学生が多いので、助けてください。
