Numpy.ufunc size change warning

1

So I have installed the 1.3 release, using the binary installer from here. (Linux, Python 3.7 version) The system is running Lubuntu 18.04 LTS.

Whenever I start Psi4, I get the following warning message in stdout:

numpy.ufunc size changed, may indicate binary incompatibility. Expected 192 from C header, got 216 from PyObject

Has anyone ever seen this message? It does not seem to actually cause problems, but does sound a bit ominous.

It’s absolutely fine – has to do with how numpy was compiled and who manages a particular (expected) warning. Can get rid of it by downgrading to numpy 0.15 (I think) or probably by upgrading by now. But the latest 0.16 build 0 on the day of packaging had that, so there 'tis in the installer.
