Call result.infer_objects(copy=False) instead. To opt-in to the future behavior, set `pd.set_option('future.no_silent_downcasting', True)`\r\n```\r\n\r\nThis is caused by `.fillna(False)` in the following:\r\n```python\r\ncurves_df = pd.merge(\r\n    p_curves_df, cp_curves_df, how=\"outer\", sort=True\r\n).fillna(False)\r\n```\r\n\r\nI am no developer, but I did some reading about the warning and this seems to be a clean (and possible the \"correct\") way to get rid of it:\r\n```python\r\nwith pd.option_context('future.no_silent_downcasting', True):\r\n    curves_df = pd.merge(\r\n        p_curves_df, cp_curves_df, how=\"outer\", sort=True\r\n    ).fillna(False).infer_objects()\r\n```\r\n","author":{"url":"https://github.com/mkaut","@type":"Person","name":"mkaut"},"datePublished":"2024-09-26T08:23:13.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/143/windpowerlib/issues/143"}
