Hi,
I would be very happy of some help trying to work out a numpy package binary incompatibility.
I'm trying to work out what's happening for this ticket:
https://github.com/scipy/scipy/issues/3863
which I summarized at the end:
https://github.com/scipy/scipy/issues/3863#issuecomment-51669861
but basically, we're getting these errors:
RuntimeWarning: numpy.dtype size changed, may indicate binary incompatibility
I now realize I am lost in the world of numpy / scipy etc binary compatibility, I'd really like some advice. In this case
numpy == 1.8.1 scipy == 0.14.0 - compiled against numpy 1.5.1 scikit-learn == 0.15.1 compiled against numpy 1.6.0
Can y'all see any potential problem with those dependencies in binary builds?
The relevant scipy Cython c files seem to guard against raising this error by doing not-strict checks of the e.g. numpy dtype, so I am confused how these errors come about. Can anyone give any pointers?
Assuming the message is not bogus, I would try import von_mises with a venv containing numpy 1.5.1, then 1.6.0, etc... to detect when the change happened. David
