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.
