Henrikh Kantuni created ARROW-14267:
---------------------------------------
Summary: Cannot convert DataFrame with geometry `numpy.dtype`
cells to Table
Key: ARROW-14267
URL: https://issues.apache.org/jira/browse/ARROW-14267
Project: Apache Arrow
Issue Type: Bug
Components: Python
Affects Versions: 5.0.0
Reporter: Henrikh Kantuni
Example:
{code:java}
import geopandas as gpd
import pandas as pd
import pyarrow as pa
path = gpd.datasets.get_path("naturalearth_lowres")
data = gpd.read_file(path)
df = pd.DataFrame(data)
table = pa.Table.from_pandas(df)
print(table)
{code}
Throws the following error:
{code:java}
Traceback (most recent call last):
