Description

I get a segmentation fault with simply printing a basic table creation from arrays:

 

import pyarrow as pa
import pyarrow.parquet as pq

simple_fields = [
    pa.field('POS', pa.uint32()),
    pa.field('desc', pa.string())
]


simple_schema = pa.schema(simple_fields)

simple_from_array = [pa.Array([1]), pa.Array(['bla'])]
simple_table = pa.Table.from_arrays(simple_from_array, ['POS', 'desc'])
print(simple_table)
