I have written this code, and I want to run it on IBM hardware using API_TOKEN. My code is showing this error.

from qiskit import IBMQ 
# IBMQ.delete_account()
IBMQ.save_account('API_TOKEN', overwrite=True)
IBMQ.load_account()

Showing error in the line:'IBMQ.load_account()'

a: Credentials are already in use. The existing account in the session will be replaced.

b: Retrieve the hub/group/project sets available to the user.The first entry in the list will be the default set, as indicated by hub, group, and project, respectively.

IBMQ.load_account is for running instead of IBMQ.save_account. The first time, you save. From that point own, you can load it.

NOTE: consider that after qiskit-ibmq-provider 0.20 (released in January 2023), the prefer package to connect with IBM quantum systems is qiskit-ibm-provider.
