Hi all, I am developing a namespace pipeline and have come into an issue when using Neptune to track my experiments. When I pass 
"neptune_run"
as an input to a pipeline node I get the following error: 
ValueError: Pipeline input(s) {'NAMESPACE.neptune_run'} not found in the DataCatalog
Where 
"NAMESPACE"
is my namespace pipeline name. Is there a way to use Neptune along with namespace pipelines? Thanks again.

At which point did you get this error? Did you still have the error if you are not running with neptune. I assume you are using their plugin, if you uninstall it do you still get error?
a
If I set 
enable: false
in 
neptune.yml
I do not get this error.
I can also run the first nodes in my pipeline with 
enable: true
and track the run with Neptune. However, in one of my final nodes I want to upload error metrics. So I pass 
"neptune_run"
as an input to this node. Within the function called at this node I run: 
neptune_run["evaluation/metrics"] = error_metrics
to track the error metrics. This is the point at which I get the 
ValueError
above. Should I implement this in a different way?
Thanks for the response @Nok Lam Chan

In that case, I think it’s likely a 
kedro-neptune
issue,. maybe worth asking it in #C03RKPCLYGY. I would also suggest asking in their repository https://github.com/neptune-ai/kedro-neptune since this is a community maintained plugin.

Ok will do, thanks @Nok Lam Chan

@Andrew Doherty could you share the complete traceback?

Of course

ValueError: Pipeline input(s) {'dah_market.neptune_run'} not found in the DataCatalog
Due to the namespace adding in the prefix "dah_market" (my namespace) it appears that Kedro then sees this as a dataset rather than the 
neptune_run
object. I wonder if I could pass the 
neptune_run
as a literal to the function using partial. I'll try tomorrow as I need to dig into how this works.
Any thoughts @Juan Luis?
j
no more thoughts for now, haven't looked into this in depth yet but I intend to do so. if you have any further findings drop them here @Andrew Doherty, there's a chance this is an actual bug
a
OK thanks @Juan Luis . Shall I raise this as an issue in 
kedro-neptune
Github?
j
yes, go ahead - the worst that can happen is that it isn't an actual bug 🙂 but will be good to draw their attention. I don't see them in this Slack.

Hi @Juan Luis, I got a response on the Github issue which doesn't touch on the specific Namespace pipeline challenge I am experiencing - https://github.com/neptune-ai/kedro-neptune/issues/66#issuecomment-1554557741. I think I need to create a basic example to share. Do you have any advice on how to create a simple reproducible Namespace Pipeline for this?
j
@Andrew Doherty thanks for your patience. maybe following the Spaceflights example? https://docs.kedro.org/en/0.18.0/tutorial/namespace_pipelines.html#adding-a-namespace-to-the-data-processing-pipeline you could put that in a repository and try to reproduce the problem. then write in the issue how to do so (
git clone spaceflights-modular && cd spaceflights-modular && kedro run
)
a
Nice @Juan Luis, that's very helpful. I'll work on that.

Hi @Juan Luis. I have added the following comment with a reproducible example. https://github.com/neptune-ai/kedro-neptune/issues/66#issuecomment-1561367556
Let me know your thoughts
j
that looks perfect 💯 thanks @Andrew Doherty! hoping for the maintainers to respond, otherwise we can do some debugging
a
Great, thanks @Juan Luis. If the "neptune_run" object could be imported into the file where the pipeline is defined we could use partial to pass it to the function rather than as a node input here: https://github.com/adoherty21/kedro_neptune_namespace_issue/blob/6abd300ff5980b953[…]/src/basic_namespace/common/pipelines/common_pipeline_01_raw.py If you have any thoughts on how we could do that this would be a neat work around.

Hey all, Siddhant here from neptune.ai 👋 Here's an update: https://github.com/neptune-ai/kedro-neptune/issues/66#issuecomment-1564608359 I've asked our devs to have a look, but since the same behavior works fine with normal pipelines, I think we might need support from Kedro's engg. team as well. I'll keep the thread updated. Have a great weekend!

Hi all, just to confirm that @Siddhant Sadangi provided a workaround which has been tested and works. https://github.com/neptune-ai/kedro-neptune/issues/66 Thanks all for your time and effort.

Fantastic news!
we have an issue for Kedro now by the way https://github.com/kedro-org/kedro/issues/2646
