When using pandoc to convert (in my case) markdown to latex, it generates only the “text” but without the header, \usepackages etc., and it fails when using pdflatex.

To generate a standalone file there’s the -s/--standalone option:

pandoc -f markdown -t latex -o bench.tex -s 2022-11-20-221120-1419-benchmark-tasks-for-evaluation-of-language-models.md
