Same issue, on Ubuntu 22.04. Maybe I got a bit further, but still not working. First error I got was the same:
[...]
File "/home/r98inver/.local/lib/python3.10/site-packages/pybertini/system/__init__.py", line 50, in <module>
import _pybertini.system
ModuleNotFoundError: No module named '_pybertini'
Per sudo make install
it is located in /usr/local/lib/python3.10/site-packages
, so tryed export PYTHONPATH="${PYTHONPATH}:/usr/local/lib/python3.10/site-packages"
. Solved the issue, but now I get
[...]
File "/home/r98inver/.local/lib/python3.10/site-packages/pybertini/system/__init__.py", line 50, in <module>
import _pybertini.system
ImportError: libbertini2.so.1: cannot open shared object file: No such file or directory
As suggested in this answer, I run export LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:/usr/local/lib"
. Now it works but the test got multiple errors, including
TypeError: No Python class registered for C++ class std::complex<double>
Traceback (most recent call last):

This one surprises me. Hmm.
The others, precision stuff, doesn't. boost::multiprecision made some breaking changes in 2018 or so, and I haven't had time to fix the internal code thoroughly since then.
What are you intending to do with Bertini 2? Are you aware that the software is experimental? If you're looking for a mature system for numerical algebraic geometry, please use Bertini 1. Though it lacks a Python interface, it's much more stable than Bertini 2. There are a number of other packages I could also recommend, too.
A bit of context may be helpful: My most recent work on B2 was Summer 2021, when a student and I implemented straight-line-programs as an alternative way to evaluate systems. But I never made the switch over to use them by default, and B2 continues to have precision issues due to the breaking changes in boost::multiprecision.
Alas, I ended up at a teaching university, and the community at large didn't pick up the torch for Bertini 2 when I stopped having 40 hours a week to devote to it as I did when I was a postdoc... I would welcome help on B2, if you're into it.
Actually I have Bertini1.6 up and running, wrapped by Julia. I was just looking for python interface. I'm quite new to Bertini (and starting getting involved in computational algebraic geometry in general) but i would love to help with it as far as I can
