Capturing logger output from Python

[tchittesh]

I'm using the python symforce.opt.Optimizer which is printing optimization info

[2025-01-10 01:44:21.428] [info] LM<sym::Optimize> [iter   21] lambda: 4.768e-03, error prev/linear/new: 0.000/0.000/0.000, rel reduction: 0.15934
[2025-01-10 01:44:21.447] [info] LM<sym::Optimize> [iter   22] lambda: 2.384e-03, error prev/linear/new: 0.000/0.000/0.000, rel reduction: 0.19686
[2025-01-10 01:44:21.467] [info] LM<sym::Optimize> [iter   23] lambda: 1.192e-03, error prev/linear/new: 0.000/0.000/0.000, rel reduction: 0.25366

Is there a way to capture this output (generated by spdlog in C++) or redirect it to stdout? Some naive approaches like

from symforce import logger as symforce_logger, LOGGING_FORMAT as SYMFORCE_LOGGING_FORMAT
symforce_logger.handlers.clear()
handler = logging.StreamHandler(sys.stdout)
handler.setLevel(logging.WARNING)
formatter = logging.Formatter(SYMFORCE_LOGGING_FORMAT)
handler.setFormatter(formatter)
symforce_logger.addHandler(handler)

don't seem to work
