This is my code:

from qiskit import IBMQ

provider = IBMQ.get_provider('ibm-q') 
qcomp = provider.get_backend('ibmq_16_melbourne')
QiskitBackendNotFoundError: 'No backend matches the criteria'

1 Answer 1


Unfortunately, ibmq_16_melbourne was retired. You can see the list of all the retired systems in this website.

You can list of all the backends in your provider doing this:

[p.name() for p in provider.backends()]
