Failed to load model class 'CircuitComposerModel' from module '@quantum/ibm-q-lab-widgets' about qiskit-metapackage

[mtreinish]

The ibm-q-lab-widgets package isn't part of qiskit, as far as I know it's a closed-source/proprietary package that doesn't have a public issue tracker or a direct contact email address to report any issues. I'll ask people inside IBM for the current status of the package and will leave a comment here if I have any update.

But, I am going to close this issue as there isn't anything we can do in Qiskit about this because the package is not part of the qiskit project.

I did reach out to the team inside IBM that maintained the package. They confirmed that the published version of the package did not work with recent versions of jupyter, they also said that nobody is maintaining the published package any more and it's not on their development roadmap to continue supporting it. It looks like they have deleted the pypi package (or at least I don't see it on pypi anymore) since.

Thank you. I hope you will contact them soon.

I really like composing quantum circuits on Jupyter Lab, instead of on Jupyter Notebook.

Thanks for the reply.
I am just asking about using only CLI in my lab, and all members accepted this, so using the GUI composer is no longer required.

Anyways, hope the project will have the GUI on the web early. Still, the GUI is better.
