I'm running `Python 3.5.2` and `numpy 1.15.0` I'm seeing: ``` /usr/lib/python3.5/importlib/_bootstrap.py:222: RuntimeWarning: numpy.dtype size changed, may indicate binary incompatibility. Expected 96, got 88 return f(*args, **kwds) /usr/lib/python3.5/importlib/_bootstrap.py:222: RuntimeWarning: numpy.dtype size changed, may indicate binary incompatibility. Expected 96, got 88 return f(*args, **kwds) ``` According to this [stackoverflow question](https://stackoverflow.com/questions/40845304/runtimewarning-numpy-dtype-size-changed-may-indicate-binary-incompatibility) I shouldn't see this warring as it was silence since `numpy 1.8` Why do I see it? and does it means anything?
