Bug report checklis

• Searched the issues page for similar reports

• Read the relevant sections of the documentation

• Browse the tutorials and tests for usefull code snippets and examples of use

• Reproduced the issue after updating with pip install --upgrade pandapower (or git pull)

• Tried basic troubleshooting (if a bug/error) like restarting the interpreter and checking the pythonpath

Reproducible Example

import pandapower as pp


pp.runpm_ac_opf(net)
pp.runpm_ac_opf(net, optimizer="ipopt")

Issue Description and Traceback

Running above code, I got this error

JuliaError: Exception 'Failed to precompile PandaModels [2dbab86a-7cbf-476f-9afe-75ffd3079e7c] to "/Users/macbookair/.julia/compiled/v1.10/PandaModels/jl_eidSz9".' occurred while calling julia code:
using PandaModels

On the other hand, I can run PowerModels directly using julia from Python just fine.

import julia
julia.install(quiet=True)

from matpower import path_matpower_cases

from julia import Main


Main.eval("""
    using PowerModels
    using Ipopt
    using JuMP

    nlp_solver = JuMP.optimizer_with_attributes(Ipopt.Optimizer, "tol"=>1e-6, "print_level"=>0)
""")

func_name = 'case9'
file_path = f"{path_matpower_cases}/{func_name}.m"

Main.eval('solver = optimizer_with_attributes(Ipopt.Optimizer, "tol" => 1e-6)')
result_ac  = Main.eval(f'solve_opf("{file_path}",   ACPPowerModel, solver)')

Expected Behavior

I can Main.eval just fine, PandaModels that relies on that should be able to run just fine.

Installed Versions

Turns out, it is because PandaModels requires Cbc, and Cbc requires Cbc-2.10.0. Need some acrobatic as brew didn't support old Cbc.

julia
import Pkg
Pkg.rm("Cbc")
exit()
sudo cd /usr/local/lib
sudo curl -LO https://github.com/coin-or/Cbc/archive/refs/tags/2.10.0.tar.gz
sudo tar -xvzf 2.10.0.tar.gz
cd Cbc-releases-2.10.0
sudo ./configure
make
sudo make install
julia
ENV["JULIA_CBC_LIBRARY_PATH"] = "/usr/local/lib/Cbc-releases-2.10.0/lib"
import Pkg
Pkg.build("Cbc")
using Cbc

Now, the bug became

FAILED test_pandamodels_runpm.py::test_compare_pwl_and_poly - pandapower.auxiliary.OPFNotConverged: PowerModels.jl OPF not converged

The error of bus_dc might be related to #2413. I will close this and track it there.
