    Description

      It's convenient to infer the data type so that users can just write pyarrow.Array.from_pandas(arr), however, sometimes users want fine-grained control, e.g., if we have an object type numpy array, whose values are all null. When we convert it to an arrow column vector, we may need a specific type instead of NullType.
