@<1523701205467926528:profile|AgitatedDove14> Thank you, ill try to do that !

is this code running inside the Task that is you data processing? Assuming it does check this code, it will fetch the pipeline and then the task you need

previous_task = Task.get_task(
        project=Task.current_task().project,
        task_name="process_dataset", #use "process_dataset" name from pipe
        task_filter={'status': ['completed']})

Notice using the current Tasks project and to make sure you are looking for a component running under the same pipeline

Hi @<1523701205467926528:profile|AgitatedDove14> . I got Task.get_task to work by using the name passed in pipe. add_step but not with the task_name set in Task.init of the data_processing.py file. I want to understand if there's a better way than just passing task_name to parameter_override? If not, then can I understand why pipeline has to override task_name with the add_step name?

main.py

prefix='Args/'
pipe.add_step(
    name="process_dataset",
    base_task_project=project_name,
    base_task_name="data_processing",
    parameter_override={} #removed parameters for code clarity
)

src/data_processing/data_processing.py

task_name='data_processing'
task = Task.init(project_name=project_name, 
task_name=task_name,task_type='data_processing')

#access the previous successful runs artifact
#this doesnt work when running as pipeline but works when run independently
previous_task = Task.get_task(
        project_name=project_name,
        task_name=task_name,
        task_filter={'status': ['completed']})
#this works when running on pipeline
previous_task = Task.get_task(
        project_name=project_name,
        task_name="process_dataset", #use "process_dataset" name from pipe
        task_filter={'status': ['completed']})

Oh I see, try the following to get a list of all pipelines, then with the selected pipeline you can locate the component:

pipeline_project = Task.current_task().project

pipelines_ids = Task.query_tasks(task_filter=dict(
                project=[pipeline_project],
                type=["controller"],
                system_tags=["pipeline"],
                order_by=["-last_change"],
                search_hidden=True,)
            )
# take the second to the last updated one (becuase the last one is us)
pipeline_id = pipelines_ids[1]

# get all components, or select the one that is you based on name?
components_ids = Task.query_tasks(task_filter=dict(
                project=[pipeline_project], parent=pipeline_id)
)

# 

I might have some typos here., but it should generally work

Hey there @<1523701205467926528:profile|AgitatedDove14> . So essentially i have a task called "data_processing" that I run in my pipeline. I just want to access old artifacts(dataframe) of my "data_processing" task inside my current "data_processing" task and append new rows to it on my current run and save the updated dataframe. This was not an issue when i run my task alone but when i run it as a pipeline it seems like its not finding old runs of the task.

Hi @<1631826770770530304:profile|GracefulHamster67>
if you want your current task:

task = Task.current_task()

if you need the pipeline Task from the pipeline component

pipeline = Task.get_task(Task.current_task().parent)

where are you trying to get the pipelines from? I'm not sure I understand the use case?

From what I understand while looking at the clearml UI is that pipelines don't exactly run under projects directly but under .pipeline so it would look like MyProject/.pipelines/Pipeline Demo .
