Research direction
Review the linked line in python/mleap/sklearn/pipeline.py around line 121 to understand the missing deserialization. Examine how deserialization is implemented for other transformers in the same file or elsewhere in the MLeap codebase. Check recent commits and discussions for any context on serialization patterns and potential approach for implementing pipeline deserialization.
