I’m trying to develop a qiskit noise model using pennylane-qiskit, but there seems to be some issue between the packages.
Here is the code I’m running in my juptyer notebook.
import qiskit
import pennylane as qml
import qiskit.providers.aer.noise as noise
# create a bit flip error with probability p = 0.01
p = 0.01
my_bitflip = noise.pauli_error([('X', p), ('I', 1 - p)])
# create an empty noise model
my_noise_model = noise.NoiseModel()
# attach the error to the hadamard gate 'h'
my_noise_model.add_quantum_error(my_bitflip, ['h'], [0])
dev4 = qml.device('qiskit.aer', wires=1, noise_model = my_noise_model)
The error is on the last line. Here is the specific error message. I’ve tried reinstalling the packages and fiddling with the different versions but with no luck.

Thank you in advance for the help
!

. Glad this is working for you now!
