Cannot show my graph when I use the package for the conference

Question

I'm going to take part in this conference and editing the paper using the recommended package and template which you can download from the same page (see Submission Instruction)

Here's the problem:

When I try to put my graph on like this:

\begin{figure}
  \centering
  \includegraphics[width=\linewidth]{check.png} 
  \caption{this is a test}
  \label{test}
\end{figure}

the error message comes up.

cannot determine size of graphics (no bounding box)

I looked for the solution and found out that adding this might solve the problem:

\usepackage[dvipdfmx]{graphicx}

But now another error appears:

option clash for package graphicx

I know I should comment out the original one, but I cannot find where the original code is written.

Please give me any tips for it. Thank you

Answer 1

For reference, I obtain the same result as Marijn reorted in comment 1 and comment 2 on Windows with Texmaker+pdflatex. What I did:

• created a folder confPaper
• copied l4dc2024.cls and l4dc2024-sample.tex there (i.e. avoided a regular install)
• compiled the sample file
• MikTex-console complained jmlr.cls is missing in my installation
• allowed its installation
• compile finished successfully

Next I copied your image and your code snippet into the sample file as a new \section{Drawings}: it compiled without problems. So, without further checks, package graphicx must be included already.

Suggestion: Check, remove or update jmlr.cls on your system. This package is available via ctan.

BTW: class jmlr.cls is loaded in line 18 \LoadClass[pmlr]{jmlr} inside of l4dc2024.cls.

P.S.

A few words about accessing and working with the jmlr.cls class.

The best way of course is always to use the installation process supported by the Latex distribution used. However, as the comments suggest, this isn't always easy to do. So here's a kind of bypass solution.

Obtaining the class

You can find it on ctan here. While you could read the .pdf from there, here probably the .zip file is more interesting:

Once you downloaded (just click on said link) and opened the zip file, it shows the typical TDS-structure. I.e. you'd copy each directory (i.e. its contents) to the appropriate directories on your system, AND most likely have to tell your distribution to update its database (so it really can find it).

Bypass

Without having tried it, this should work for you:

• open the zip file
• move to /tex/latex/jmlr
• copy the 3 files to the same directory of your conferencePaper.tex

When you now compile your conference-paper, it will look first locally (and happily finds the requested class), and via its database of Latex-packages elsewhere in the TDS-tree, if it doesn't find it locally.

Caveat

Please be aware that jmlr.cls loads more classes or packages. So you may end up with a very crowded conference-folder ... but it should work, at least.

However, with a few extra folders, e.g. /img for your images, a final release to the conference should still be "easy" to do.

Files

For your reference, this is the content in my confPaper folder (while the jmlr.cls is certainly loaded from the MixTex installation; I think I just put it there for inspection).
