Hello everyone,
I am trying to get Feature-engine transformers pass the check_estimator tests
and there is one test, that I am not too sure what it is intended for.
The transformers fail the check_transformer_data_not_an_array because the input
is a _NotAnArray class, and Feature-engine transformers don't like that.
What is this check intended for? Is it to ensure compatibility with some other
sklearn class? if yes, which ones?
I would appreciate any info or links to docs/ issues.
Thanks a lot!
Sole
