Sampler.__init__() got an unexpected keyword argument 'options'

[s110m]

I tried to run the following cell in sec1_basic.ipynb:

from torchquantum.plugin.qiskit.qiskit_plugin import tq2qiskit
from torchquantum.plugin.qiskit.qiskit_processor import QiskitProcessor

processor = QiskitProcessor(use_real_qc=False, ibm_quantum_token='token', max_jobs=1)
circ = tq2qiskit(q_dev, model)
circ.measure_all()

res = processor.process_ready_circs(q_dev, [circ])

# this is the expectation value
print(res)

However, I got the following error related to torchquantum\plugin\qiskit\qiskit_processor.py:

self.sampler = AerSampler(options={"backend_options": backend_opts}, seed=self.seed_simulator)
# self.sampler = AerSampler(backend_options=backend_opts, seed=self.seed_simulator)
logger.info(f"Initialized AerSampler.{' With noise model.' if self.noise_model else ''}")

Error message:

TypeError: Sampler.__init__() got an unexpected keyword argument 'options'

The problem here is that AerSampler use Sampler not SamplerV2
You could change the import in torchquantum\plugin\qiskit\qiskit_processor.py: from qiskit_aer.primitives import SamplerV2 as AerSampler

You can create a pull request for that if this solve your issue
