deprecations:
|
|
- |
|
|
The `NetworkX <https://networkx.org/>`__ converter functions for the
|
|
:meth:`.DAGCircuit.to_networkx` and
|
|
:meth:`~.DAGCircuit.from_networkx`, along with the
|
|
:meth:`.DAGDependency.to_networkx` method have been deprecated and will be
|
|
removed in a future release. Qiskit has been using
|
|
`retworkx <https://qiskit.org/documentation/retworkx/>`__ as its graph
|
|
library since the qiskit-terra 0.12.0 release, and since then the networkx
|
|
converter functions have been lossy. They were originally added so
|
|
that users could leverage functionality in NetworkX's algorithms library
|
|
not present in retworkx. Since that time, retworkx has matured
|
|
and offers more functionality, and the :class:`~.DAGCircuit` is tightly
|
|
coupled to retworkx for its operation. Having these converter methods
|
|
provides limited value moving forward and are therefore going to be
|
|
removed in a future release.
