Chapter 10 Running circuits on the pulse simulator

[Ye2018]

When I tried to run the code about "running circuits on the pulse simulator". I got AerError information:
Traceback (most recent call last): Input In [32] in <cell line: 35> results = backend_sim.run(pulse_qobj, system_model=system_model) File /opt/conda/lib/python3.8/site-packages/qiskit/utils/deprecation.py:27 in wrapper return func(*args, **kwargs) File /opt/conda/lib/python3.8/site-packages/qiskit/providers/aer/backends/pulse_simulator.py:242 in run return super().run(schedules, validate=validate, **run_options) File /opt/conda/lib/python3.8/site-packages/qiskit/utils/deprecation.py:27 in wrapper return func(*args, **kwargs) File /opt/conda/lib/python3.8/site-packages/qiskit/providers/aer/backends/aerbackend.py:191 in run self._validate(qobj) File /opt/conda/lib/python3.8/site-packages/qiskit/providers/aer/backends/pulse_simulator.py:348 in _validate raise AerError("PulseSimulator requires at least one Acquire " AerError: 'PulseSimulator requires at least one Acquire instruction per schedule.'
I wonder if anyone can help me to figure out how to get the correct result.

Hey @Ye2018 , I am going through the same section right now and finding that the book is significantly out of date when it comes to running circuit on the pulse simulator. The Aer PulseSimulator is now deprecated. Pulse simulations should now be run through Qiskit Dynamics. While not EXACTLY the same example as Loredo has published in Chapter 10, the Qiskit Dynamics Docs have a nice tutorial on how to perform pulse simulations in the current state of the art.
