upgrade:
|
|
- |
|
|
It is now no longer possible to instantiate a base channel without
|
|
a prefix such as :class:`qiskit.pulse.Channel` or
|
|
:class:`qiskit.pulse.PulseChannel`. These classes are designed to be
|
|
parent classes for different user facing channel classes, such
|
|
as :class:`qiskit.pulse.DriveChannel`, and not something directly used.
|
|
When instantiated directly they were not actually usable. If you were
|
|
previously directly instantiate either :class:`qiskit.pulse.Channel` or
|
|
:class:`qiskit.pulse.PulseChannel` this no longer works.
