LaTeX build failure, looking for generated images in incorrect location

Describe the problem

The sphinx latexpdf builder is failing due to an inability to find .png files that are generated when executing notebooks.

Here's the last line prior to failure from the latex .log file:

./networkx_reference.tex:90523: Unable to load picture or PDF file 'build/jupyt 
er_execute/reference/tutorial_82_0.png'.                                        
<to be read again>                                                              
                   }

Which seems to indicate that the latex builder is looking for the tutorial_82_0.png image in the jupyter_execute/reference directory. However, the tutorial_82_0.png file does exist one directory up (i.e. jupyter_execute/tutorial_82_0.png). Note also that the tutorial.md that is being executed to generate these images lives in the top-level directory, not in the reference/ subdirectory:

Additional context

There are no corresponding problems with the html builder
I've also tried this in an environment with jupyterbook-latex installed - this had no effect.
