Is Jinja2 sintax working on kedro

0.18.12

? I tried writting my catalog as:

{% for group in ["A", "B", "C"] %}

my_dataset_{{group}}:
  type: pandas.ParquetDataSet
  filepath: data/03_processed/my_dataset/group={{group}}/my_dataset.parquet

{% endfor %}

but I got the error

ParserError: Invalid YAML or JSON file <my_path>/conf/base/catalog.yml, unable to read line 0, position 1.

Are you using a

TemplatedConfigLoader

? See https://docs.kedro.org/en/stable/configuration/advanced_configuration.html#how-to-use-jinja2-syntax-in-configuration

no, I’m using

OmegaConfigLoader

Jinja only works with

TemplatedConfigLoader

. I'm 99% sure you can use dataset factories for this; see https://docs.kedro.org/en/stable/data/kedro_dataset_factories.html#how-to-generalise-datasets-of-the-same-type.
