[jira] [Created] (ARROW-2228) Unsigned int type for arrow Table not supported

Marcello created ARROW-2228:
-------------------------------

             Summary: Unsigned int type for arrow Table not supported
                 Key: ARROW-2228
                 URL: https://issues.apache.org/jira/browse/ARROW-2228
             Project: Apache Arrow
          Issue Type: Bug
          Components: Python
         Environment: Ubuntu 16.04
python3.6.3
            Reporter: Marcello


Running this line of python

```

pa.Table.from_pandas(pd.DataFrame(\{'foo': [np.array([10000000000000000000], dtype=np.uint64)]}))

```

I get

`ArrowInvalid: trying to convert NumPy type int64 but got uint64`

 

the problem possibly relies on the fact that from_pandas doesn't handle the conversion from python object to unsigned integer.
