Rendering pweave pmd with python module

Question

I have a python code that generates a report in .pmd format, and then renders it as an html with this command:

import subprocess
cmd_pweave = "pweave -f md2html file.pmd"
subprocess.run(cmd_pweave, shell=True, check=True)

I want to avoid calling the terminal, because that can be a problem with integrability with windows (right now I'm using a mac).

So the question is: is there a way to render this pmd file to html with the python pweave library? I've looked through the doc, but I can't find how to do it.

It should be something like:

import pweave
# Weave a pandoc document with default options
pweave.weave('file.pmd')

Python pweave module doc is here http://mpastell.com/pweave/pweave.html#simple-weaving-and-tangling and an example in pmd is here: http://mpastell.com/pweave/_downloads/FIR_designp.pmd

Any help is appreciated

UPDATE: here is the traceback
