Akousapandas KeyError: column not foundA DataFrame column access failed because the specified column name does not exist.
The column name you referenced does not exist in the DataFrame. Common causes: typos, extra whitespace in column names, different case, or the column was dropped/renamed earlier in the pipeline.
Check available columns: df.columns.tolist(). Strip whitespace: df.columns = df.columns.str.strip(). Use df.get('col', default) for safe access. Verify column names after read_csv() or transformations.
