Optionally convert output of FeatureExtraction pipeline to list
What is the purpose of .tolist in FeatureExtraction pipeline?
Why is it called? Is this because of some kind of compatibility issue?

If someone needs to use __call__ a lot, it only slows it down. I've tried subclassing FeatureExtractionPipeline, but it's very ugly since then I can't just use it with pipelines.pipeline.
Hi @lambdaofgod,

.tolist() call is there as Python's lists are more compatible with CSV/JSON serialisation than numpy array.

Did you have a chance to get number of how actually slower it is ? If the difference is non negligible then we might have a look to optimise .tolist() only when serialising through JSON/CSV<|||||>This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.
