Hello! I’m using the IBMProvider package to be able to use my research access to IBM’s backends, so I need to define the instance that I want to access in order to use the dedicated device, but Pennylane always sends my jobs to the open access instance, instead of the one I provided in the provider. When I try to use the qiskit.remote option in qml.device I get an error saying that the backend I provided does not exist. Here instance is the code to access the research instance, sorry I can’t share it.
import pennylane as qml
from pennylane import numpy as np
import pennylane_qiskit as pq
from qiskit_ibm_provider import IBMProvider
import qiskit
provider = IBMProvider(instance=instance)
backend = provider.get_backend("ibm_perth") #The backend I reserved
ibm_dev = qml.device('qiskit.remote', wires=3, backend=backend, shots=nshots)
I get the error message

Hey @Pedro_Alvarez!
Can you post the output of qml.about()?
There you go @isaacdevlugt

I see it now, how can I install qiskit.remote?
I got it, just had to update pennylane-qiskit
Great! Yeah always a good idea to check that you’re using the most up-to-date versions of everything
