upgrade:
|
|
- |
|
|
The deprecated transpiler routing pass, ``BIPMapping`` has been removed.
|
|
It was marked as deprecated in the Qiskit 0.43.0 release. It has been
|
|
replaced by an external plugin package: ``qiskit-bip-mapper``. Details for
|
|
this new package can be found at the package's github repository:
|
|
|
|
https://github.com/qiskit-community/qiskit-bip-mapper
|
|
|
|
The pass was made into a separate plugin package for two reasons, first
|
|
the dependency on CPLEX makes it harder to use and secondly the plugin
|
|
package more cleanly integrates with :func:`~.transpile`. The optional
|
|
extra ``bip-mapper`` to install the ``cplex`` and ``docplex`` to support
|
|
this pass has been removed as nothing in Qiskit optionally requires it anymore.
