  • Qiskit Aer version: 0.4
  • Python version: 3.6+
  • Operating system: Linux

When Terra tries to load Aer provider, with numpy 1.15.4, which was default on our Aqua build, and conforms to > 1.13 we get this

line 440, in <module>
    from .cy.spmath import (zcsr_transpose, zcsr_adjoint, zcsr_mult)
  File "stringsource", line 105, in init qiskit.providers.aer.pulse.qutip_lite.cy.spmath
AttributeError: type object 'qiskit.providers.aer.pulse.qutip_lite.cy.spmath.ar' has no attribute '__reduce_cython__'

We have tried locally and get similar error with 1.15.4. (I was running 1.16.3 which seems ok, and latest 1.18.1 seemed fine too)

Bump minimum required version of numpy
75abe9f 
It appears that the newly added pulse simulator has an implicit
requirement on having a newer version of numpy installed. We should
encode this minimum in the aer package requirements so people don't
accidently install aer with a version of numpy too old to work.

Fixes Qiskit#592

Just for the record, this is a bug in Cython 0.27, not a NumPy issue. It has been fixed in 0.28 and later.

Hi @nonhermitian, I have the same error here but my Cython is 0.29.2. Do you have any idea? Thx

Yeah. They said it fixed but it is not. Numpy needs to be updated.

Bump numpy on poBranch
27544d7 
The translated docs builds are failing because of Qiskit/qiskit-aer#592
which is caused by using a version of numpy incompatible with the pulse
simulator. This has been fixed in aer on master and the stable/0.4.0
branch pending a 0.4.1 release. But, until that is ready we need to
manual ensure we're using a newer numpy version to avoid this issue in
the docs builds.
