CLI: SyntaxError: f-string expression part cannot include a backslash

[matgille]

Hi @mittagessen,

There seem to be an error with the CLI, I've got a
SyntaxError: f-string expression part cannot include a backslash with the following command:
party -d cuda:0 ocr -i ../entrainements_htr/front_justice/front_justice_150_p_htr/11_J_76-0633.xml out_fra.xml --load-from-repo 10.5281/zenodo.15075344 -l fra.

Party was installed following the instructions on the README, on python 3.10.

Problematic line is in party/cli/pred.py:

@click.command('ocr',
               epilog=f"""
\b
Language codes known to party:
{'\n'.join(' -> '.join((k.replace("_", " ").title(), v)) for k, v in LANG_TO_ISO.items())}
                       """)

Replacing the \n char with any other character fixes the problem. I can provide a fix if you want.

Best,

Matthias

Hm, it works for me. Which python version are you using?

Thanks for your answer. It was on python 3.10, I believe. Retried with python 3.12 and it works well.
