Question on Executing Metaflow Workflow from Python Script Without 'run' Argument about metaflow HOT 4 CLOSED

May I ask for your use case specifically. Not exactly what you are asking for but we will soon have a runner (ie: able to run in python) but Metaflow will handle the running itself. It should be equivalent to what you are trying to do here (unless you want to do funky things between steps). See here: #1732. This should be out soon.

Thank you for your response and the ongoing developments in Metaflow. My main objective is to simplify the execution of Metaflow workflows, transitioning from the traditional command python train.py run to simply python train.py. This adjustment would enhance the usability and integration of Metaflow within our automation scripts and larger application ecosystem.

Here is how I am currently setting up the workflow to achieve this:

from metaflow import FlowSpec, step

class ExampleFlow(FlowSpec):
    @step
    def start(self):
        print("This is the start step.")
        self.next(self.end)

    @step
    def end(self):
        print("This is the end step.")

if __name__ == '__main__':
    ExampleFlow().run()

By including ExampleFlow().run() in the if name == 'main': block, the workflow initiates directly when the script is executed with python train.py. This setup works for our basic workflows, and I am curious to know if this method aligns with best practices within the Metaflow framework.
