fix: pandas 2.2+ SettingWithCopyWarning compatibility#1219
Merged
Conversation
pandas 2.2 removed `pandas.errors.SettingWithCopyWarning`, which broke nest_plotters import on modern pandas. Guard the import so the warning filter is only applied when the class exists. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
