hey all, I noticed something that when i define the following node:

node(
    func=sample_func,
    # name="sample_func"    -> does not work when this is commented
    inputs="epubdf",
    outputs="result"
)

and then run this test:

kedro_session.run(node_names=['sample_func'])

I get an error saying name doesnt exists but when i specify name parameter in node itself it works. I thought if i don't provide it, name would be equal to func name itself, no?

Node name is optional, so if you haven't specified it, it will be

None

I see, would it make sense to make it default to

func.___name___

? Or was there a reason why it wasn't?

The name was just added for visualisation in Kedro Viz and has no functional purpose.

hmm but session run uses it somehow. if i wanna run a single node in my pipeline, it breaks

would it make sense to make it default to

func.___name___

?

it's been discussed, it's a backwards-incompatible change but I actually think we should do it, have a look at https://github.com/kedro-org/kedro/issues/3575

Thanks, that's what i hit now with not able to run a single node unless name param is specified. I also run the

kedro registry describe __ default __

which returns func names so i thought it was working but tests fail. Reading the thread, i also see it has other issues with default as well so i guess for now i'll put the names manually 😄

@Fazil Topal The simple reason for this is, you can use the same function for different node and that default wouldn't work.

Makes sense. Thanks for the explanation
