--------------------------------------
Summary: pa.array raises for mixed scalar types (float16 + int)
Key: ARROW-9817
URL: https://issues.apache.org/jira/browse/ARROW-9817
Project: Apache Arrow
Issue Type: Bug
Components: Python
Affects Versions: 1.0.0
Reporter: Andrew Wieteska
pa.array raises with mixed scalars for np.float16 and a numpy int:
{code:java}
In [1]: import numpy as np
...: import pyarrow as pa
...: pa.array([np.float16(1.5), np.int64(5)])

---> 84 raise ArrowInvalid(message)
85 elif status.IsIOError():
86 # Note: OSError constructor is

{code}
Do we expect this to work?
