Is python 3.12 supported?

My program fails when trying to profile using yappi through 3.12 (works fine with cProfile)

I'm seeing this when I use yappi in combination with unittest.mock and Python 3.12. Removing any of those three elements fixes the issue. Here's a repro:

from unittest import mock
import yappi

if __name__ == "__main__":
    yappi.start()
    mock.MagicMock()
    yappi.stop()

Traceback:

Traceback (most recent call last):
  File "/Users/santorella/miniconda3/envs/ax_312_test/lib/python3.12/unittest/mock.py", line 656, in __getattr__
    elif self._mock_methods is not None:
         ^^^^^^^^^^^^^^^^^^

    raise AttributeError(name)
AttributeError: _mock_methods

The above exception was the direct cause of the following exception:

    mock.MagicMock()
