Hey guys, I'm trying to do a "for loop" on the catalog, so I am using TemplatedConfig so I can use jinja. I am trying with the following way, and I am not sure why it is not working. Catalog:

{%- for item in mylist %}
out.blind_predictions_{{ item-}}:
    type: pandas.CSVDataSet
    filepath: ${filepath1}_{{ item-}}.csv
    layer: out
{% endfor %}

Globals:

mystli:
    - item1
    - item2

(For obvious reasons I removed the actual names from the text here) Does anyone know how to accomplish this? (do a for here)

https://docs.kedro.org/en/stable/configuration/advanced_configuration.html#how-to-use-jinja2-syntax-in-configuration You may need to create your custom config loader,

mylist

can be interpolated with

${my_list}

but it cannot be used to form the for-loop.

Wow, I had no idea about this dataset factory. I will try it out.

It's relatively new feature, we are still trying to improve the docs so we haven't promoted this feature yet.

I am using kedro 0.18.3, but I don't seem to have config.OmegaConfigLoader, do I need to upgrade my kedro?

You will need to upgrade your kedro version.

So the for works, but I cannot use variables? Hmm, that's weird haha
