OSError: [Errno 8] Exec format error

Not sure if this library is still supported, but FWIW:
Python 3.6.2 (default, Jul 17 2017, 16:44:45)
Type 'copyright', 'credits' or 'license' for more information
IPython 6.2.1 -- An enhanced Interactive Python. Type '?' for help.

Is definitely still supported, what made you think otherwise?
What os are you using? Does it work when converting raw html?
What processor architecture are you on?
Pydf comes bundled with a binary for amd64, if you're on another architecture you'll need to supply your own binary.
There wasn't any activity for about six months, no PRs, no issues... This
is either the sign of dropped support or exceptional attention, and the
former is the case 99% of the time. happy to hear it's the latter, and
thank you!
It doesn't work when converting raw HTML either.
I'm using MacOS 10.13.1. FWIW you may wish to say specifically that only
amd64 are bundled; I was misled by this fairly definitive statement:
Wkhtmltopdf binaries are precompiled and included in the package making
pydf easier to use, in particular this means pydf works on heroku.
I'll install wkhtmltopdf and try again. thanks.

sorry, 10.13.1 is orthogonal to your question; it's a MacBook, so Intel
Core i7

You'll need to download a binary for wkhtmltopdf which works on mac and set the WKHTMLTOPDF_PATH environment variable so pydf uses it. I've added a note to the beginning of the readme to that effect.
There haven't been any changes over the last 6 months because wkthmltopdf hasn't released a new stable version and nothing has gone wrong. When I say "nothing" I mean TutorCruncher alone generates well over 1m pdfs a month with pydf, both using the pypi package and the docker container; I can't remember a single error over that time with pydf.
