Hello, this error is not new, probably due to my data, is there any recommended approaches to reduce or eliminate this?

Lib\site-packages\stonesoup\measures.py:259: RuntimeWarning: invalid value encountered in sqrt
  return np.sqrt(super().__call__(state1, state2))

I saw this in another post, would something like this be possible for measures.py?

if turn_rate[0] == 0:

turn_rate = Matrix([np.finfo(float).eps])
