What is the current behavior?

Importing Aer raises a ValueError when using numpy 1.18.1:

ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 88 from C header, got 80 from PyObject

Steps to reproduce the problem

Install qiskit 0.23.5, numpy 1.18.1, import Aer.

What is the expected behavior?

Aer can be imported.

Suggested solutions

This error goes away after upgrading to numpy 1.20. Was the failing file compiled with numpy 1.20 and the requirement needs to be updated?

mtreinish commented 3 years ago

This is a duplicate of #1120 it should be fixed on master for the 0.8 with https://github.com/Qiskit/qiskit-aer/pull/1125 but for the 0.7.x series I'm working on https://github.com/Qiskit/qiskit-aer/pull/1123 to use a minimum supported numpy version for the release binary builds instead of the latest numpy release. #1125 isn't backportable because the 0.7.x series is directly using the numpy api via cython code in the pulse simulator (which is where this error is coming from) which has been removed from master.
