I imagine that these phantom dependencies will prevent parallelization. Is there a workaround?

yes, they might... workaround might be a bit ugly but copy pasting the functions and changing the name
BTW: I'll check when is the next RC scheduled for, maybe it will already contain a fix 🤞

PanickyMoth78 thank you for the mock code, I can verify it reproduces the issue. It seem that for some reason (bug) when the same function is called multiple times it "collects" parents, hence the odd graph,
BTW: if you want to see exactly what is passed to the step you can press on the step's full_details, and see the hyperparameter section.
I'll make sure we fix this bug in the next RC.

feature request: tell me what gets passed along each edge of the pipeline graph

Nice! please feel free to add to GH issue 🙂
Hmm yes that is odd, let me see if I can reproduce

feature request: tell me what gets passed along each edge of the pipeline graph

(I see the same thing in some evaluation code that I've written so I thought I'd reproduce it in the standard example)

Sure. It is a minor change from the code in the clearml examples for pipelines.
I just repeat the last two pipeline steps from that code in a loop (x3)
https://github.com/allegroai/clearml/blob/master/examples/pipeline/pipeline_from_decorator.py

The additional edges in the graph suggest that these steps somehow contain dependencies that I do not wish them to have.

PanickyMoth78 I think I understand what you are saying, but it is hard to see if there is a "bug" here or a feature...
Can you post the full code of the pipline?

I think this should be a valid use of pipelines. for example - at some step I choose to sweep across several values of some parameter and the rest of the steps are duplicated for each value of that parameter.
