It is actually empty

Well it needs to be populated!

Hahaha! Yeah, I'd imagine. Last week it was working fine. I thought since you have a parameters/ folder and then a YAML file for each pipeline it was getting those through there

so if it's mapped in a pipeline, it needs to be there - even if you're not calling it. This open PR I was just looking at actually has the right answer here: https://github.com/kedro-org/kedro/pull/1424/files#diff-fb71c3224b6465dcb63b9daff7d185ea9fda1fa61464d8670e7ba917b2e8fdb1R85

The

conf/base/parameters/data_science.yml

is indeed populated with:

model_options:
  test_size: 0.2
  random_state: 3
  features:
    - engines
    - passenger_capacity
    - crew
    - d_check_complete
    - moon_clearance_complete
    - iata_approved
    - company_rating
    - review_scores_rating

model_options_experimental:
  test_size: 0.2
  random_state: 8
  features:
    - engines
    - passenger_capacity
    - crew
    - review_scores_rating

I thought you were referring to the

conf/base/parameters.yml

, which is empty

can you type

kedro -V

I think you have accidentally upgrade to 0.18.x which has breaking changes

and if you compare to the PR needs to be updated to have the pipeline

namespace

as the top level

I do have 0.18.0; but I'm pretty sure I have not upgraded since I last run the pipeline

The snippet you posted would have worked in 0.17.7 so maybe you were looking at an older version of the docs

I see. I just checked again and indeed the docs have been changed

No, actually they have not been changed--my bad

I will use the updated docs from the PR you sent me though and hopefully it will solve my issues. Thanks for the help! Note to self: be more aware of updates to projects you're not familiar with and read the release notes! 😉

I think the tutorial is broken and that pr is the fix. So in this case it's us not you! Thanks

Hello, could anyone help me finding good example for YAML file being used

kedro run -c config.yml

. I see the official documentation says nothing about

--from-nodes

. I am afraid I have a case that

kedo 0.18.0

ignores my option provided in

run.from-nodes

What does your

config.yml

looks like?

I tried to use

from-inputs

and

from-nodes

None of them work. However

to-nodes

works 😉

run:
    pipeline: vtb_pupil2iris
    env: vision_tests
    from-inputs:
        - vision_test_bunch

Ok, let me quickly have a try.

Do underscores work?

YES

Seems so, I remember it is always like this (at least in 0.16.x), but not sure is this by design or not. I remember I have seen some discussion about making it consistent with the cli.

@Rafał to-nodes doesn't work either, you also have to do the underscore.

Thank you. Thats why I asked for example. My observation is like that -

to-nodes

can be the list in YAML -

from_nodes

(unse underscore) - should be the string with comma separated node names Strange

I am afraid that

to-nodes

worked in my case. Will check it.

to-nodes

isn't pick up by the cli at all, so maybe that's why it is not complaining the list.

What? Why not picked up? Here is some kedro --help

Options:
  --from-inputs TEXT        A list of dataset names which should be used as a
                            starting point.
  --to-outputs TEXT         A list of dataset names which should be used as an
                            end point.
  --from-nodes TEXT         A list of node names which should be used as a
                            starting point.
  --to-nodes TEXT           A list of node names which should be used as an
                            end point.

@Rafał I mean in the

yaml

file, if you do

kedro run --to-nodes

it works .

As you notice in the yaml file you have to use underscore instead of the

-

Thanks. But anyway would be great to put such info in official kedro docs. And I still do not know how to pass the list. I am afraid that one can not use the syntax

from_nodes:
    - node1
    - node2
