   Can you provide a reproducible example?
   
   Looking at the example output of the data, you are working with complex data type? That is already not supported by Arrow (although the error traceback you show is about a different data type):
   
   ```
   In [22]: pa.array(np.array([1+1j, 2, 3]))
   ...
   ArrowNotImplementedError: Unsupported numpy type 15
   ```
