My code is:
from qiskit import IBMQ
IBMQ.load_account()
provider = IBMQ.get_provider('ibm-q')
qcomp = provider.get_backend('ibmq_16_melbourne')
but I run it in Jupyter I get the following message
QiskitBackendNotFoundError Traceback
(most recent call last)
<ipython-input-6-f874d37829a9> in <module>
2 IBMQ.load_account()
3 provider = IBMQ.get_provider('ibm-q')
----> 4 qcomp =
provider.get_backend('ibmq_16_melbourne')

I have already made an account at IBM, and have already seen the post (Trying to get a provider from IBMQ but get 'No provider matches the criteria.'), but the problem still exists.
