Psuedocode crashes build post merge

[glemieux]

Description

After successfully passing a pull request automated build test, the post-merge build fails.

Looking at the raw build output from readthedocs, this is failing in the post html build step where I think readthedocs is trying to render a PDF and EPUB version of the documentation.

Exception occurred:
  File "/home/docs/checkouts/readthedocs.org/user_builds/fates-users-guide/envs/latest/lib/python3.9/site-packages/docutils/nodes.py", line 2056, in unknown_departure

NotImplementedError: <class 'sphinx.writers.latex.LaTeXTranslator'> departing unknown node type: pseudocodeContentNode
The full traceback has been saved in /tmp/sphinx-err-8ma5ua57.log, if you want to report the issue to the developers.
Please also report this if it was a user error, so that a better error message can be provided next time.
A bug report can be filed in the tracker at <https://github.com/sphinx-doc/sphinx/issues>. Thanks!

Suggested fix

Unknown at this time. Short term fix to try is to disable the PDF and EPUB builds.

Disabling the pdf and epub build option in the readthedocs.yaml config file alleviates the issue, so this is definitely a problem with the pseudo code generator and latex. I'm going to leave this open for now assuming that generating a pdf is ideal, although not necessary.

Potential future investigation should look at building the pdf directly through sphinx without the use of readthedocs to see if this fails in the same manner. Failing that it might be good to post to the pseudocode issues page.

• Attempt to build pdf using latex without readthedocs
