Python 3.11: ValueError: mutable default <class 'numpy.ndarray'> for field w1 is not allowed: use default_factory

[lucasw]

I'm seeing this on Ubuntu 23.04 and python 3.11, I think it's due to dataclass changes:

terminate called after throwing an instance of 'pybind11::error_already_set'
  what():  ValueError: mutable default <class 'numpy.ndarray'> for field w1 is not allowed: use default_factory
