Hi @jwoehr, you should have the latest version of qiskit. you can try with

• pip uninstall qiskit
• pip install qiskit

The current version that I'm using is Qiskit 0.17.4

[alejomonbar]

Additionally, I will update the Jupyter notebook with the Qiskit version information. I completely forget about it. @jwoehr

[alejomonbar]

At the end of the README file is the version of the different libraries of Qiskit used. @jwoehr

[alejomonbar]

Oh, I see. I have the "qiskit-optimization" version '0.3.0'. Did you try uninstalling and reinstalling the Qiskit package? @jwoehr

[alejomonbar]

Better if you try this one pip install qiskit-optimization

[jwoehr]

I uninstalled qiskit-optimization then did this:

$ pip install qiskit-optimization
...
Successfully installed qiskit-optimization-0.2.3

Are you installing qiskit-optimization by building from main branch of a checkout?

[alejomonbar]

Yes, I'm using the latest version because I'm doing some contributions to the Qiskit optimization library. But, you should be able of executing those libraries with qiskit_optimization version 0.2.3. I tried it using the IBM Quantum lab which has version 0.2.3 and it works. A suggestion is to use directly the IBM quantum Lab to execute the notebook or maybe you have to restart your kernel. @jwoehr
