What are some common errors when using scikit-learn pipelines?
Some common errors include not properly chaining transformers, using incompatible data types, and forgetting to fit the pipeline.
Can you explain what you mean by not properly chaining transformers?
Sure! Not chaining transformers means that you might forget to pass the output of one transformer as the input to the next, which can lead to errors.
What happens if I use incompatible data types?
Using incompatible data types can cause the pipeline to fail during fitting or transformation, as some algorithms expect specific formats.
How can I debug these errors effectively?
You can debug by checking the shapes of your data at each step, using Pipeline
