Question

hey guys I have a code which has kind of submodels in it 3 of them They follow the same naming pattern for execution nodes The problem is i can t put them all under `default` because names are not unique Is recommended way to solve this using tags or namespaces Or do i have to change the names to be unique manually

Namespaces are your friend here

datajoely · Answer

for this exact problem

Cool will try to use namespaces then +1 thankyou

Fazil B. Topal · Answer

I have the following problem now Without passing namespaces i used the following convention in data catalog already ```modelA orders modelB orders modelC orders modelA pipeline modelB pipeline modelC pipeline ``` So namespaces when i pass to `pipeline` function creates looks for the following entry in the catalog `modelA modelA orders` which i solve by not being explicit but i have the following function ```node func inputs= modelA=modelA pipeline modelB=modelB pipeline modelC=modelC pipeline ``` How can pass this without being explicit thinking face

datajoely · Answer

are you using a dynamic pipeline here

Fazil B. Topal · Answer

Nope only 3 models and so far i didn t pass `namespace` anywhere but explicityle created catalog params with modelA B C prefix

datajoely · Answer

okay gotcha

Fazil B. Topal · Answer

I so far invoked individual runs on my machine for instance just running p modelA or something

Fazil B. Topal · Answer

I wonder if tags would just solve it smile

datajoely · Answer

we are talking about explicitly adding the namespace to the pipeline piece right ```ds pipeline 1 = pipeline pipe=pipeline instance inputs= model input table namespace= active modelling pipeline ```

Fazil B. Topal · Answer

yes right now I have 3 submodels a b c and final model takes those submodels so I was referring them explicitly in the node All catalog params looks namespaced but python code doesn t refer to namespace param as i did everything manually wiring

Fazil B. Topal · Answer

Adding code piece here for clear reference That s it is defined now namespace is not passed anywhere in the code

datajoely · Answer

okay namespace is applied at a pipeline level

datajoely · Answer

the docs are here <https docs kedro org en 0 18 13 nodes and pipelines modular pipelines html>

Fazil B. Topal · Answer

In the pipeline function im also not passing namespace smile My catalog I have defs like `drivingTime modelPipeline s3`

Fazil B. Topal · Answer

I use kedro pipeline don t import it from modular pipeline as well

datajoely · Answer

so that method should still have a `namespace=` kwarg

Fazil B. Topal · Answer

pipeline has param called namespace yes

Fazil B. Topal · Answer

I first passed but then kedro tries to load `modelA modelA orders` so kind of double namespace issue

datajoely · Answer

you may have to change your ` ` since that s somewhat reserved

datajoely · Answer

namespaces are a little tricky to get the hang of maybe worth running through the tutorial before migrating your existing stuff

Fazil B. Topal · Answer

I see but you re saying using tags wouldn t solve the issue it has to be namespaced
