Don't call PipelineController functions after start has finished. Use a post_execute_callback instead
` from clearml import PipelineController

def some_step():
return

def upload_model_to_controller(controller, node):
print("Start uploading the model")

if name == "main":
pipe = PipelineController(name="Yolo Pipeline Controller", project="yolo_pipelines", version="1.0.0")

pipe.add_function_step(
    name="some_step",
    function=some_step,
    cache_executed_step=False,
    post_execute_callback=upload_model_to_controller
)

pipe.start() `
