New Pyomo version bug?

[samgdotson]

Here's what I know, last week (2/20/2024) I could run an osier.CapacityExpansion problem just fine and the output would look something like this

Working configurations

platform	python version	pyomo version
Win10	3.9.3	6.4.1

==========================================================
n_gen  |  n_eval  | n_nds  |      eps      |   indicator  
==========================================================
     1 |       10 |      1 |             - |             -
     2 |       20 |      1 |  0.000000E+00 |             f
     3 |       30 |      1 |  0.000000E+00 |             f
     4 |       40 |      1 |  0.000000E+00 |             f
     5 |       50 |      1 |  0.000000E+00 |             f

Now, the problem still runs but the output is a lot less pretty

What I have tried

1. I plugged the error into Google, found this post from 2018. I can verify that this problem only occurs when a model is unfeasible. However, that will be the case for many many models tested in osier because that's just how genetic algorithms work so it would be nice to turn off whatever error message is causing this.
2. I checked the verbosity settings -- the verbosity is as high as it can possibly go.

   logging.getLogger('pyomo.core').setLevel(verbosity)`   # default = logging.Critical

3. I also tried

   import warnings
   warnings.filter('ignore')

4. I reinstalled osier in two fresh conda environments. One with Python 3.9 and the other with Python 3.10. I also tested it with Pyomo versions 6.4.1 and 6.7.1 (see above configurations) -- this behavior is only present with the most recent pyomo version, 6.7.1. This pyomo update was released this week which is consistent with the timeline where my code was working fine on Friday and today it is not. Especially since it was previously working on two other machines with more recent versions of pyomo, bet less recent than the current (until I updated them today and now they're broken).

5. I have tried specifying the pyomo version in setup.py under the install_requires parameter, however doing so results in the following error message

# What needs to change

This issue can be closed when `setup.py` specifies a version of  `pyomo<=6.7.0`. 

**OR**

Update the way `osier` is installed per the line in the error message `C:\Users\samgd\anaconda3\envs\pyomo64\lib\site-packages\setuptools\__init__.py:80: _DeprecatedInstaller: setuptools.installer and fetch_build_eggs are deprecated.`

@yardasol would you mind helping with this?

@samgdotson I think your best bet for now is to fix your setup.py so you aren't using the deprecated setuptools.installer, AND put a version requirement on pyomo.
