Ok, created a temporary repo for that https://github.com/Zemeio/kedro_experiment/tree/main/new-kedro-project

I think this is because you are using namespace in your pipeline, so

metric

should be

data_science.active_modelling.metric

. You are seeing MemoryDataSet because the kedro cannot find the corresponding entry, thus it thinks it is a in memory variable. @User I think when we update the spaceflights tutorial to namespace pipeline, the section after that has not been updated to align with it.

So it should always be namespaced, no exceptions?

It depends on your use case, the main usage of namespace is when you have a lot of pipeline you start to have name collision

Or, only when you specify the namespace in the pipeline?

you can always use a namespace=None, which just fallback to a normal pipeline

Yes I think the exp tracking docs went in the same time as the namespace update and aren't aligned

I got a different error now, after namespacing, so it was the namespace problem.

The companies column is still saved on MemoryDataSet using that, is that intended? When I namespaced the MemoryDataSet it gave me an error

I have updated the gist,

companies_columns

should be

data_processing.companies_columns

instead. Please update the catalog again.

It works, but kedro viz is not updated with the metrics values

Thank you for staying with the tutorial, we will make sure the documentation is updated soon. I don't have a quick idea what's happened with viz, if it's not working, feel free to raise an Issue on Github or discord.

Ok, I will try to do some digging before I raise an issue, thank you for your time/help!

Are you able to solve the viz problem?

Sorry, I went to work and had a lot of overtime, so I wasn't able to touch it yet.

Rough day! No worries I will try to see if I can reproduce the issue.

Were you able to reproduce? I checked my session store and it doesn't have any relevant information, I don't know if it should have.

Sorry, I haven't started yet. I am working on something, but this will be next item to work on.

Sorry for disturbing, I will sleep soon, tomorrow if you haven't been able to find anything I will continue digging.

I wasn't able to reproduce the issue. This is the repo I am using with kedro==0.18.0 https://github.com/noklam/kedro_viz_demo

Weird, I cloned your repo, created a venv with my python 3.8.5, ran pip install on your requirements, and ran the application, after that I used viz and the same thing happened. I am running on windows, maybe I will dockerize and see if the problem happens on linux?

Just to confirm, all the files are there but nothing rendered?

The files under data are created just fine

What's your viz version?

I got it working using docker, so maybe it is a windows thing. Do you want me to share the dockerfile?

That would be great!

Awesome! This is great.

Thank you for your help debugging this @Zemeio

It was my pleasure = ).
