Latex：IEEE会议模板中出现undefined control sequence includegraphics问题解决方法

Posted 2023-02-23 DM--Tutor

  最近要参加一个IEEE主办的国际会议，使用中官网提供的Latex模板写论文，当插入EPS格式的图片时，提示错误：undefined control sequence \\includegraphics。 说明Latex无法识别\\includegraphics， 在前面的程序中加入\\usepackagegraphicx还是不行，偶然在一个国外网站发现解决方案，现总结于此：

找到前面的graphic related packages

% *** GRAPHICS RELATED PACKAGES ***
%
\\ifCLASSINFOpdf
  
   <span style="color:#ff0000;">\\usepackage[pdftex]graphicx</span>
  % declare the path(s) where your graphic files are
   <span style="color:#ff0000;">\\graphicspath../pdf/../jpeg/</span>
  % and their extensions so you won't have to specify these with
  % every instance of \\includegraphics
   <span style="color:#ff0000;">\\DeclareGraphicsExtensions.pdf,.jpeg,.png</span>
\\else
  % or other class option (dvipsone, dvipdf, if not using dvips). graphicx
  % will default to the driver specified in the system graphics.cfg if no
  % driver is specified.
  <span style="color:#ff0000;"> \\usepackage[dvips]graphicx</span>
  % declare the path(s) where your graphic files are
   <span style="color:#ff0000;">\\graphicspath../eps/</span>
  % and their extensions so you won't have to specify these with
  % every instance of \\includegraphics
  % \\DeclareGraphicsExtensions.eps
\\fi

由于默认的情况是全部注释掉的，都无法在程序中使用。

解决方法：把上图中红色的部分取消掉注释，在运行就可以了。
