Does not work when running code remotely

[BramVanroy]

I am running my code through SSH. My connecting device is a Windows 10 computer, and the machine actually doing the training is a linux server. When I use knockknock, though, I get the following trace.

Traceback (most recent call last):

The above exception was the direct cause of the following exception:

keyring.errors.InitError: Failed to create the collection: Prompt dismissed..

It states "Item does not exist" but I'm not sure which item it's referring to. This happens as soon as I launch the code, so I haven't been prompted for a password. In fact, it seems that the prompt is where things go wrong.

Hmm that's strange indeed. I am solely working on instances on the cloud and have never encountered this problem.
It seems the bug stems from yagmail, and more specifically when it calls keyring (the password manager). I have to look at it more precisely...

If it matters, I am using Ubuntu 18.04.2 LTS x86_64.

Hello @VictorSanh I am also facing same issue. I am running code in cluster with OS Ubuntu 16.04.6 LTS (GNU/Linux 4.4.0-161-generic x86_64) :

from knockknock import email_sender

@email_sender(recipient_emails=["abc@gmail.com"], sender_email="def@gmail.com")
def train_your_nicest_model():
    import time
    time.sleep(300)
    return {'loss': 0.9} # Optional return value

train_your_nicest_model()

I am getting following error:

@rameshjesswani, are you sure it's the same error? It looks like it's something different causing your error... Did you make sure you gave yagmail access to the email you're using? (see here).
