Running issue with Mac and Linux

[Yuanliang-Li]

Hi,

I ran the example (semi-definite relaxation of AC-OPF) on my Mac (M2) and Linux Mint (Ubuntu 20.04), respectively. However, I got the same running problem.

The version of python, julia, pyjulia, and pandapwer are listed as follows:
Python==3.10
Julia==1.6.7
Pyjulia==0.6.1
Pandapower==2.13.2

I can make sure that the PATH of julia and python interpreter are set correctly. My python script name is pandamodel_test.py, where I have the following codes:

import pandapower as pp
import pandapower.networks as nw
net = nw.example_simple()
pp.runpm(net, pm_model="SDPWRMPowerModel", pm_solver="ipopt", pm_nl_solver="juniper")

I first ran $python pandamodel_test.py. However, the log information says "Currently, PyJulia does not fully
support such Python interpreter" and suggests me to use the command $python-jl PATH/TO/YOUR/SCRIPT.py. I followed its suggestion and run $python-jl pandamodel_test.py. Then, I got the error.

The log history is shown as follows:

julia.core.UnsupportedPythonError: It seems your Julia and PyJulia setup are not supported.

Julia executable:
    julia
Python interpreter and libpython used by PyCall.jl:
    /Users/myName/.julia/conda/3/x86_64/bin/python
    /Users/myName/.julia/conda/3/x86_64/lib/libpython3.10.dylib
Python interpreter used to import PyJulia and its libpython.
    /Users/myName/.julia/conda/3/x86_64/bin/python
    /Users/myName/.julia/conda/3/x86_64/lib/libpython3.10.dylib

Your Python interpreter "/Users/myName/.julia/conda/3/x86_64/bin/python"
is statically linked to libpython.  Currently, PyJulia does not fully
support such Python interpreter.

The easiest workaround is to pass `compiled_modules=False` to `Julia`
constructor.  To do so, first *reboot* your Python REPL (if this happened
inside an interactive session) and then evaluate:

    >>> from julia.api import Julia
    >>> jl = Julia(compiled_modules=False)

Another workaround is to run your Python script with `python-jl`
command bundled in PyJulia.  You can simply do:

    $ python-jl PATH/TO/YOUR/SCRIPT.py

See `python-jl --help` for more information.

I wish I can get you feedback since I have been strugelling in this issue for some days. I also wish to get your suggestion for the version of python, julia, pyjulia, and pandapwer, which you used in your devlopment.

Thank you!
