When I try IBMQ.load_account or IBMQ.delete_account gives an error in the ubuntu machine and the error is,

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/anaconda3/lib/python3.7/site-packages/qiskit/providers/ibmq/ibmqfactory.py", line 291, in delete_account
    stored_credentials, _ = read_credentials_from_qiskitrc()
  File "/home/anaconda3/lib/python3.7/site-packages/qiskit/providers/ibmq/credentials/configrc.py", line 86, in read_credentials_from_qiskitrc
    new_credentials = Credentials(**single_credentials)  # type: ignore[arg-type]
TypeError: __init__() got an unexpected keyword argument 'efault_provider'

The qiskit version I used is

{'qiskit-terra': '0.17.4',
 'qiskit-aer': '0.8.2',
 'qiskit-ignis': '0.6.0',
 'qiskit-ibmq-provider': '0.14.0',
 'qiskit-aqua': '0.9.2',
 'qiskit': '0.27.0', 
 'qiskit-nature': None,
 'qiskit-finance': None,
 'qiskit-optimization': None,
 'qiskit-machine-learning': None}

  • $\begingroup$ Hi @epelaaez , I tried first to save the account it gave me the same error. So I tried deleting the account again I ended up with the same error. I'm calling the function by importing IBMQ from qiskit along with my credential. $\endgroup$

  • $\begingroup$ In the last line of the error message, the parameter efault_provider is mentioned. Is this a typo from your side or is that the actual error message? $\endgroup$

  • $\begingroup$ It is the actual error message right. Because we save the account using ibmq.save_account('Key', overwrite = True) which means it is an actual error message and not a typo. $\endgroup$

  • $\begingroup$ @Monica could you post contents of your ~/.qiskit/qiskitrc file here? (hide the token before posting) $\endgroup$ Jun 21, 2021 at 10:47

1 Answer 1


Based on the error message

TypeError: __init__() got an unexpected keyword argument 'efault_provider'

Your qiskitrc file contains an invalid keyword efault_provider (it should be default_provider). You'll need to delete your $HOME/.qiskit/qiskitrc file and do save_account() again.

  • $\begingroup$ Thank you @jyu00, I deleted the file and it worked for me. $\endgroup$
