problem for installation verifying

[Yunita YuChih]

Hello everyone, 

I tried to verify the installation of the qutip following the instruction of the guide, but the result of the verifying comes out with:

AttributeError: 'numpy.ndarray' object has no attribute 'dag'

and the whole result is as following:

There seems to be some problem with the packages for the three level system, and how should I fixed it?

Another problem is that, I  see that the items of OPENMP Installed and INTEL MKL Ext are showing false. Will these influence anything? And if those do lead to something  wrong for my running, what should I do to solve them?

(I am conducting the with Jupyter notebook, python 3.8.7, anaconda for python 3.8, mac OS X 10.11.6)

Thank you very much

Hello Yunita,

QuTiP is not currently compatible with Numpy 1.20 due to changes in how Numpy 1.20 handles array_like objects. We are working to make a new release which will work. In the meantime, you can work around the issue by pinning your version of Numpy to be 1.19 or lower.

Thank you for you replying, Jake. I tried to changed my version of Numpy to 1.19.3( pip install numpy==1.19.3, from https://pypi.org/project/numpy/1.19.3/#files)

but then the installation verifying become like this:

--------------------------------------------------------------------------- ValueError Traceback (most recent call last) <ipython-input-1-7a62d45c5c81> in <module> ----> 1 import qutip.testing as qt 2 qt.run() ~/.local/lib/python3.8/site-packages/qutip/__init__.py in <module> 177 178 # core --> 179 from qutip.qobj import * 180 from qutip.qobjevo import * 181 from qutip.states import * ~/.local/lib/python3.8/site-packages/qutip/qobj.py in <module> 58 import qutip.settings as settings 59 from qutip import __version__ ---> 60 from qutip.fastsparse import fast_csr_matrix, fast_identity 61 from qutip.cy.ptrace import _ptrace 62 from qutip.permute import _permute ~/.local/lib/python3.8/site-packages/qutip/fastsparse.py in <module> 421 #Need to do some trailing imports here 422 #------------------------------------- --> 423 from qutip.cy.spmath import (zcsr_transpose, zcsr_adjoint, zcsr_mult)~/.local/lib/python3.8/site-packages/qutip/cy/__init__.py in <module> ----> 1 from qutip.cy.spmatfuncs import * ~/.local/lib/python3.8/site-packages/qutip/cy/spmatfuncs.pyx in init qutip.cy.spmatfuncs() ValueError: numpy.ndarray size changed, may indicate binary incompatibility.

how could I fixed it now?

I'm not sure how you've installed QuTiP, but you need to recompile it. I'd suggest fully uninstalling whatever you've done, and following the installation steps in the documentation (making sure to keep `numpy~=1.19`): http://qutip.org/docs/latest/installation.html. In particular, if at all possible, installations through conda will be much more resilient than ones through pip.

I have reinstalled everything, and the result now comes out with 
AttributeError: partially initialized module 'qutip' has no attribute 'settings' (most likely due to a circular import)

I looked at the other post, but the condition for the promulgator of that post is using window. What can I do with mac?

I finally being able to run it without error, but I found that my versions are :

QuTiP Version:      4.5.3

Numpy Version:      1.18.0

Scipy Version:      1.6.0

Cython Version:     0.29.21

Matplotlib Version: 3.3.4

Python Version:     3.8.5

Is that 4.5.3 for qutip okay to use?

Yes - we released 4.5.3 specifically to solve the Numpy problems you mentioned in your first email. Glad to hear it's working!
