Error in qiskit IBMQ.load_account() - Account Credentials Not Found

I am using the ''ibmq_vigo" backend by calling IBMQ.load_account(), which is an example in qiskit documentation for NoiseModel.

from qiskit import IBMQ, Aer
from qiskit.providers.aer.noise import NoiseModel

provider = IBMQ.load_account()
backend = provider.get_backend('ibmq_vigo')
noise_model = NoiseModel.from_backend(backend)

When I run the above code in my Jupyter Notebook, I encountered this error:

IBMQAccountCredentialsNotFound: 'No IBM Quantum Experience credentials found.'

Any help here?

I believe you havn't link your IBMQ account to your local device. If you are using IBMQ device for the first time, copy a token from your IBMQ account and save your token:

IBMQ.save_account(TOKEN)
