In the qm interface, the regular expression pattern triggers the following warning after upgrading to Python 3.12

Starting with Python 3.12, invalid backslash escapes are elevated from DeprecationWarning to SyntaxWarning. In a future release, this will become a SyntaxError. (https://docs.python.org/3/whatsnew/3.12.html#other-language-changes)

AttributeError: module 'numpy' has no attribute 'float'.
`np.float` was a deprecated alias for the builtin `float`. To avoid this error in existing code, use `float` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted
 the numpy scalar type, use `np.float64` here.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
    https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations
