I was trying the qiskit Terra tutorial and it seems that the code provided to connect to an actual quantum computer doesn't run properly. With my API token generated and stored into the variable "my_token", I typed :


and got the following error message :

TypeError                        Traceback (most recent call last)
<ipython-input-21-7eeefb4c8c69> in <module>()
----> 1 IBMQ.save_account(my_token)
      2 IBMQ.load_accounts()

    134         """
    135         credentials = Credentials(token, url, **kwargs)

    123     filename = filename or DEFAULT_QISKITRC_FILE

    126     # Check if duplicated credentials are already stored. By convention,

---> 63         new_credentials = Credentials(**single_credentials)
     64         credentials_dict[new_credentials.unique_id()] = new_credentials

TypeError: __init__() missing 1 required positional argument: 'token'

Please tell me where I got it wrong.

I was able to reproduce your issue by changing the key a few times... seems to be a bug.

Either way, I was able to resolve my issue by removing the qiskitrc file.

rm ~/.qiskit/qiskitrc (your location may vary)

After that, set the key again and you should be good.
