Passwordless ssh still asks for password when running as subprocess

I had setup passwordless ssh (keygen) to access my remote workspace from my personal laptop. On the remote server, I do use an account with a password to connect. Setting up public/private key authentication allowed me to connect without having to type this password.
The Python script I am running uses subprocess.Popen() to ssh into this remote workspace again. However, it is not a passwordless ssh during this. I have checked my permissions and have tried to delete and recreate the keys, yet this still happens.
Below is the relevant piece of Python code.
subprocess.Popen(['ssh', machine_addr, 'cd ' + workspace +
'; python dispynode.py --serve 1 --clean --dest_path_prefix dispytmp_' + str(i)])
ssh python

What do you mean when you say passwordless? The account you are trying to log in is really passwordless? Are you using ip based authentication? Are you using public/private key authentication?

I have clarified what I meant by passwordless. I am using key authentication.

Is your key passphrase protected? Is the password ssh asks the remote host password or the key passphrase?

Before I set up the keys, I used a password to access the server.

Are you usingssh-agenton the client to manage the SSH keys? If so, are you executing the Python script in an environment where theSSH_AUTH_SOCKenvironment variable is available? Are you executing your Python script as yourself or as another user?

Are you using
ssh-agent on the client to manage the SSH keys? If so, are you executing the Python script in an environment where the SSH_AUTH_SOCK environment variable is available? Are you executing your Python script as yourself or as another user?– Kusalananda
