How can I log in to mlfoundry on a device in a non-interactive mode?

If you are running automated training jobs, you can use the TFY_HOST and TFY_API_KEY environment variable to set the API Key. You do not need to use the mlfoundry login command if you are using environment variables.

The API key passed via the environment variable takes precedence over the API key passed via the login command.

export TFY_HOST=  # e.g.
export TFY_API_KEY="your-api-key"
