将LaTeX2WP与Python一起使用时出现问题-TypeError:“float”对象不能解释为整数

我最近安装了 LaTeX2WP

测试时 latex2wp.py example.tex 在命令提示符中,返回以下错误

C:\Latex2Wordpress>latex2wp.py DCT.tex
Traceback (most recent call last):
  File "C:\Latex2Wordpress\latex2wp.py", line 657, in <module>
    s=extractbody(s)
  File "C:\Latex2Wordpress\latex2wp.py", line 153, in extractbody
    for i in range(1,(len(L)+1)/2) :
TypeError: 'float' object cannot be interpreted as an integer

错误是由于 latex2wp 文件由LaTeX2WP下载提供。我想我可以调整这两行并修复错误消息。

我已经把所有的 粗体的 两条相关线路:

"""
The program makes several passes through the input.

In a first clean-up, all text before \begin{document}
and after \end{document}, if present, is removed,
all double-returns are converted
to <p>, and all remaining returns are converted to
spaces.

The second step implements a few simple macros. The user can
add support for more macros if desired by editing the
convertmacros() procedure.

Then the program separates the mathematical
from the text parts. (It assumes that the document does
not start with a mathematical expression.) 

It makes one pass through the text part, translating
environments such as theorem, lemma, proof, enumerate, itemize,
\em, and \bf. Along the way, it keeps counters for the current
section and subsection and for the current numbered theorem-like
environment, as well as a  flag that tells whether one is
inside a theorem-like environment or not. Every time a \label{xx}
command is encountered, we give ref[xx] the value of the section
in which the command appears, or the number of the theorem-like
environment in which it appears (if applicable). Each appearence
of \label is replace by an html "name" tag, so that later we can
replace \ref commands by clickable html links.

The next step is to make a pass through the mathematical environments.
Displayed equations are numbered and centered, and when a \label{xx}
command is encountered we give ref[xx] the number of the current
equation. 

A final pass replaces \ref{xx} commands by the number in ref[xx],
and a clickable link to the referenced location.
