is it just this script that you are running that breaks? What happens if instead of pipe.upload_model you call
print(pipe._get_pipeline_task())?

Traceback (most recent call last): File "/home/mano/Desktop/askui-stuff/ml-models/pipelines/yolo/pipeline_yolo.py", line 163, in <module> print(pipe._get_pipeline_task()) File "/home/mano/anaconda3/envs/askuienv/lib/python3.9/site-packages/clearml/automation/controller.py", line 2649, in _get_pipeline_task if str(task.task_type) == str(Task.TaskTypes.controller) and cls._tag in task.get_system_tags(): AttributeError: 'NoneType' object has no attribute 'task_type'

That is very odd. Is the script above all you're running?

gives the same error

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() `
