Pyomo required by classiq is obsolete

[ChienKaiMa]

Version

• Python-3.12.1
• classiq-0.9.3
• Pyomo-6.0.1

How to replicate this problem

I created a conda environment (Python 3.12.1) and installed classiq (0.9.3).

$ pip install classiq
...
$ python3
>>> import classiq
...
.../lib/python3.12/site-packages/pyomo/core/base/component.py", line 427, in __getstate__
    state[key] = val
    ~~~~~^^^^^
TypeError: 'tuple' object does not support item assignment
>>>

• This issue is not found in my older environment with Python 3.11.4.
• I found a similar issue Issues #2600 is resolved by Pyomo team.

I have tried to force update the Pyomo package to 6.7.1, and imported classiq successfully with only a few deprecation warnings. I wonder this will break anything important.

$ pip install --force pyomo
...
$ python3
>>> import classiq
WARNING: DEPRECATED: the 'EqualityExpression' class has been moved to
'pyomo.core.expr.relational_expr.EqualityExpression'.  Please update your
import.  (deprecated in 6.4.3) (called from <frozen importlib._bootstrap>:488)

My suggestion

• Update the import code and requirements.txt.
• Use GitHub Actions to make sure mainstream versions can operate without problems.

I found the latest classiq package is 0.39.0, and checked the PyPI pages.
https://pypi.org/project/classiq/0.39.0/ shows "Requires: Python <3.12, >=3.8"
https://pypi.org/project/classiq/0.9.3/ shows "Requires: Python >=3.7, <4.0"
That's why pip found 0.9.3 and installed the old version.
Since the conda default installs Python 3.12, maybe it should be mentioned in the README.
