Hi, trying the example here https://arrow.apache.org/docs/python/pandas.html on DataFrames paragraph with python 2.7.17, numpy==1.16.2 , pandas ==0.20.3, pyarrow==0.16.0 or pyarrow==0.15.1 got an error (see below).
import pandas as pd import pyarrow as pa df = pd.DataFrame({"a": [1,2,3]}) table = pa.Table.from_pandas(df) fails with the following stacktrace: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "pyarrow/table.pxi", line 1177, in pyarrow.lib.Table.from_pandas File "/home/ubuntu/.pyenv/versions/2.7.17/envs/py27/lib/python2.7/site-packages/pyarrow/pandas_compat.py", line 593, in dataframe_to_arrays types) File "/home/ubuntu/.pyenv/versions/2.7.17/envs/py27/lib/python2.7/site-packages/pyarrow/pandas_compat.py", line 234, in construct_metadata metadata = _get_simple_index_descriptor(level, name) File "/home/ubuntu/.pyenv/versions/2.7.17/envs/py27/lib/python2.7/site-packages/pyarrow/pandas_compat.py", line 255, in _get_simple_index_descriptor pandas_type = get_logical_type_from_numpy(level) File "/home/ubuntu/.pyenv/versions/2.7.17/envs/py27/lib/python2.7/site-packages/pyarrow/pandas_compat.py", line 113, in get_logical_type_from_numpy result = _pandas_api.infer_dtype(pandas_collection) File "pyarrow/pandas-shim.pxi", line 131, in pyarrow.lib._PandasAPIShim.infer_dtype File "pyarrow/pandas-shim.pxi", line 134, in pyarrow.lib._PandasAPIShim.infer_dtype TypeError: infer_dtype() takes no keyword arguments Is some known bug, some incompatibility or some mis-configuration?
