CONFIGS CONSOLIDATIONS INTERPOLATIONS in conf config yml `ra

Question

CONFIGS CONSOLIDATIONS INTERPOLATIONS in conf config yml `random state 42` and in conf model training yml `random state $ random state ` ```kedro run gt gt gt TypeError Cannot cast scalar from dtype lt U15 to dtype int64 according to the rule safe ``` If I get this correctly the consolidation interpolation process resulted in `random state` being assigned the value ` 42 ` instead of `42` Granted I could easily circumvent this issue with `int params random state ` but I m curious and would like to know if this is an expected behavior and whether there is a more robust elegant way of handling it Thx in advance M

which config loader are you using

datajoely · Answer

you can also try this `random state int 42`

datajoely · Answer

I think that will coerce it properly <https pyyaml org wiki PyYAMLDocumentation>

Thx < datajoely> I wasn t aware of this syntax for type coercion slightly smiling face Regarding the loader I m just using the default plain vanilla `ConfigLoader` Could that be the issue Shall I use another loader Thx

Hmmm It looks like it could indeed be the issue I ve just tried to do `int params random state ` and got `ValueError invalid literal for int with base 10 $ random state ` I guess variable interpolation requires another config loader sweat smile

ah If only I read or memorized documentations better <https docs kedro org en stable configuration advanced configuration html>

datajoely · Answer

Yes but longer term the default ConfigLoader which will be replaced will have this natively
