matplotlib 中的 pgfplot 给出错误消息

Question

我已经在 python 中创建了一些图并使用模块“另存为 tikz_save”将它们导出，因此在 python 中我通过以下方式创建这些输出文件：

tikz_save(original+'/'+nameOfFigurepgf+'.pgf')

然后我想通过以下方式将这些文件包含在乳胶中：

\documentclass[]{article}

\usepackage{subfig}
\usepackage{pgfplots}
\newlength\figureheight
\newlength\figurewidth

\usepackage{hyperref}

\usepackage[]{grffile}
\begin{document}




\begin{figure}
\hspace{-2cm}
\begin{minipage}{1.\textwidth}

  \subfloat[test]{%

  \setlength\figureheight{2in}
    \setlength\figurewidth{3in}
    \InputIfFileExists{C:/....pgf}{}{\textbf{!! Missing graphics !!}}

  }
     \subfloat[test]{%

  \setlength\figureheight{2in}
    \setlength\figurewidth{3in}
    \InputIfFileExists{C:....pgf}{}{\textbf{!! Missing graphics !!}}



 }

\end{minipage} \par
 \centering
  \subfloat[]{%

   \setlength\figureheight{2in}
    \setlength\figurewidth{4in}
    \InputIfFileExists{C:/....pgf}{}{\textbf{!! Missing graphics !!}}
  }
  \caption{Some grouped images}
\end{figure}

tex tikz 文件如下所示

如果我尝试编译 tex 文件，我总是收到相同的错误消息

! Missing $ inserted.

I've inserted a begin-math/end-math symbol since I think
you left one out. Proceed, with fingers crossed.

尤其是这条信息

! Missing } inserted.
<inserted text>
}
l.1377 \end{axis}
I've put in what seems to be necessary to fix
the current column of the current alignment.
Try to go on, since this might almost work.
