Wenchen Fan commented on ARROW-1156:
------------------------------------
I just realized {{pyarrow.Array.from_pandas}} do have a type parameter by
looking at source code, guys can you fix the official document
https://arrow.apache.org/docs/python/generated/pyarrow.Array.html#pyarrow.Array
? It has style issues, and doesn't mention the type parameter, and has no
explanation for the parameters.
> pyarrow.Array.from_pandas should take a type parameter

> URL: https://issues.apache.org/jira/browse/ARROW-1156
> Project: Apache Arrow
> Issue Type: New Feature
> Affects Versions: 0.4.0
> Reporter: Wenchen Fan
>
> 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.
