How to set up the dataset to use "feat_static_cat"

[mreismendes]

Hi, I got in trouble trying to set up the training dataset to benefit from "feat_static_cat".

I got an error "GluonTSDataError: Array 'feat_static_cat' has bad shape - expected 1 dimensions, got 2."

I don't know how to shape the dataset correctly, and I also need to know if I'm setting the cardinality correctly!

I'd appreciate any kind of help.

error:

Thank you!
