The deprecated ``qiskit.IBMQ`` object hase been removed. The object was marked
as deprecated. This alias object was marked as deprecated in the 0.23.0 release.
This alias object lazily redirected attribute access to ``qiskit.providers.ibmq.IBMQ``. As the
``qiskit-ibmq-provider`` package has now been retired and superseded by
``qiskit-ibm-provider`` package which maintains its own namespace
maintaining this alias is no longer relevant. If you
were relying on the ``qiskit.IBMQ`` alias you should migrate your usage to
the ``qiskit-ibm-provider`` package, see the
`migration guide <https://qiskit.org/ecosystem/ibm-provider/tutorials/Migration_Guide_from_qiskit-ibmq-provider.html>`__
for more details.
