Numpy RuntimeWarning

Something I learns recently..

  • NumPy has its own internal warning architecture on top of Pythons, which can be specifically controlled
  • So, something Numpy will just produce a RuntimeWarning  without actually throwing an exception

Consider this:

probs = np.array([0.0, 1.0])
np.prod(probs)**(-1/len(probs))

Numpy produces a RuntimeWarning, not an exception
