研究方向
Investigate the modification of initial attributes in FeatureUnion during fitting in sklearn/pipeline.py. Refer to discussions in issues #8157 and #8350 for desired API changes. The fix likely involves ensuring init attributes are not mutated, possibly by copying or restructuring the fit method. Examine existing comments and linked PRs for guidance.
