Support for extensions of the ``qiskit`` and ``qiskit.providers`` namespaces
|
||
by external packages has been removed. Support for doing this was deprecated
|
||
in the Qiskit 0.44.0 release. In the past, the Qiskit project was composed
|
||
of elements that extended a shared namespace and hook points were added
|
||
to enable doing that. However, it was not intended for these interfaces to
|
||
ever be used by other packages. Now that the overall Qiskit package is no
|
||
longer using that packaging model, leaving the possibility for these
|
||
extensions carry more risk than benefits and has therefore been removed.
|
||
If you’re maintaining a package that extends the Qiskit namespace (i.e.
|
||
your users import from ``qiskit.x`` or ``qiskit.providers.y``) you should
|
||
transition to using a standalone Python namespace for your package.
