ImportError: cannot import name 'Digraph' from 'graphviz.dot'

I'm getting the following error when trying to use pm4py.

Traceback (most recent call last):

ImportError: cannot import name 'Digraph' from 'graphviz.dot' (C:\Users\johan\source\repos\miner\venvwin\lib\site-packages\graphviz\dot.py)

It happens both on Ubuntu 20, and Windows 10, both in Python 3.8 and 3.9. Graphviz is installed on both machines.
I've written the code on another Ubuntu machine and there it works just fine, but trying to run it on a fresh Ubuntu installation or Windows 10, I get this.

Removing the import of format_dataframe which it complains about in the top doesn't change the error, but shows the next line where I import a pm4py package.

I can't find anything about this specific error anywhere, so I'm really running out of options to run my program anywhere.

It turns out that running pip install -U pm4py solves the problem. Those are also the instructions on PyPI, but I was trying to install it from a requirements.txt file.
