upgrade:

|
The ``python-constraint`` dependency, which is used solely by the
|
|
:class:`~.CSPLayout` transpiler pass, is no longer in the requirements list
|
|
for the Qiskit Terra package. This is because the :class:`~.CSPLayout` pass
|
|
is no longer used by default in any of the preset pass managers for
|
|
:func:`~.transpile`. While the pass is still available, if you're using it
|
|
you will need to manually install ``python-contraint`` or when you
|
|
install ``qiskit-terra`` you can use the ``csp-layout`` extra, for example::
|
|
|
|
pip install "qiskit-terra[csp-layout]"
