Notice the pipeline step/Task at execution is not aware of the pipeline context

Ok the doc needs fix (edited)

suggestion?

The description says this though

A section name associated with the connected object. Default: 'General'

Sorry, don’t get it

From code perspective what changes?

So General would have created a General instead of Args?

What happens if I do blah/dataset_url ?

from here: https://github.com/allegroai/clearml/blob/5a9155b2039413280f13dfded1121470c4c4323d/examples/pipeline/pipeline_controller.py#L29

barebones, can a step in a pipeline refer to a previous step by name and get it?

this task - https://github.com/allegroai/clearml/blob/5a9155b2039413280f13dfded1121470c4c4323d/examples/pipeline/step2_data_processing.py

What’s the point of saying General?

On a related note - is it possible to get things like ${stage_data.artifacts.dataset.url} from within a task rather than passing params in add_step ?

Think multiple hyper-paremter sections that we need to reference
(under the Tasks Configuration Tab, the Hyper parameters can have multiple sections)

Is task.parent something that could help?

Exactly 🙂 something like:
# my step is running here the_pipeline_task = Task.get_task(task_id=task.parent)

That is awesome!
If you feel like writing a bit about the use-case and how you solved it, I think AnxiousSeal95 will be more than happy to publish something like that 🙂

Yes, for datasets where we need GDPR compliance

that worked, thanks AgitatedDove14

Ah ok got it.

AgitatedDove14 - mean this - says name=None but text says default is General.

Name is default None though?

Sure, you can pass ${stage_data.id} as argument and the actual Task will get the reference step's Task ID of the current execution.
make sense ?

Thanks

AgitatedDove14 is it possible to get the pipeline task running a step in a step? Is task.parent something that could help?

As per - https://clear.ml/docs/latest/docs/references/sdk/task#connect

I am essentially creating a EphemeralDataset abstraction and creating controlled lifecycle for it such that the data is removed after a day in experiments. Additionally and optionally, data created during a step in a pipeline can be cleared once the pipeline completes

"General" is the parameter section name (like Args)

Ok the doc needs fix

In params:

parameter_override={'General/dataset_urlWhat’s the General for?

Ephemeral Dataset, I like that! Is this like splitting a dataset for example, then training/testing, when done deleting. Making sure the entire pipeline is reproducible, but without storing the data long term?

So General would have created a General instead of Args?

yes,
This is a must, you have to specify the hyperparameters section you are referencing.
https://github.com/allegroai/clearml/blob/5a9155b2039413280f13dfded1121470c4c4323d/examples/pipeline/step2_data_processing.py#L21
This is actually:
task.connect(args, name='General')Basically there is no "random_state" only "General/random_state"
Make sense ?

See Args section in the screenshot
"Args/counter"
