Example script output is too sparse

[rickecon]

The output during the execution of the example script ./examples/run_ogcore_example.py is very sparse right now. I ran the script with the updated virtual environment from PR #1107. And I got the following output for the steady state and the transition path computation. My problem with this sparse output is that you don't see the root finding equation errors in the steady-state computation and you don't see the distance measures in the transition path computation. I much prefer the output setting in the current version of OG-USA's example script run_ogusa.py.

Issue:

When running Python via uv, logging.info() messages do not show by default because the Python logging module defaults to the WARNING level.

Solution:

If you want to control verbosity directly as a flag (e.g., uv run script.py --verbose), use the argparse module to capture the flag and set the level accordingly.

import argparse
import logging

parser = argparse.ArgumentParser()
parser.add_argument("-v", "--verbose", action="store_true")
args = parser.parse_args()

level = logging.INFO if args.verbose else logging.WARNING
logging.basicConfig(level=level)

Then run: uv run script.py --verbose
