Yes, I can see this is indeed not supported: https://github.com/apache/arrow/blob/bb33493bd34dcd21d71b6b942203992e67f5ef3c/python/pyarrow/src/arrow/python/arrow_to_pandas.cc#L2026-L2032 @WillAyd do you know if there's any reason for arrow to pandas to not support this? or is just a matter of someone to do the work? I am putting the full traceback because it's easier to understand what happens. ```python >>> pdf = arrow_table.to_pandas() Traceback (most recent call last): File "<python-input-2>", line 1, in <module> pdf = arrow_table.to_pandas() File "pyarrow/array.pxi", line 987, in pyarrow.lib._PandasConvertible.to_pandas File "pyarrow/table.pxi", line 5174, in pyarrow.lib.Table._to_pandas File "/home/raulcd/miniforge3/envs/py13/lib/python3.13/site-packages/pyarrow/pandas_compat.py", line 808, in table_to_dataframe result = pa.lib.table_to_blocks(options, table, categories, list(ext_columns_dtypes.keys())) File "pyarrow/table.pxi", line 4103, in pyarrow.lib.table_to_blocks File "pyarrow/error.pxi", line 92, in pyarrow.lib.check_status pyarrow.lib.ArrowTypeError: Converting unsigned dictionary indices to pandas not yet supported, index type: uint16 ``` cc @AlenkaF -- This is an automated message from the Apache Git Service.
