Troubleshooting

“Unknown transformer type”

This means your step’s transformer string does not match the FeatureEngineer dispatcher. Check spelling and casing.

Resampling errors about non-numeric columns

Oversampling/undersampling require numeric features. Apply an encoder first (e.g., OneHotEncoder / OrdinalEncoder) before resampling.

Pickle loading errors

If SkyulfPipeline.load() fails, ensure you are using compatible versions of:

• Python
• scikit-learn
• pandas

If you need portability across environments, consider constraining versions.
