pyarrow.Table.to_pandas() raise ValueError: Found non-unique column index

[maqy]

　I use pyarrow to receive the arrow data sent from java, the data type is 
int(two columns). The python code I use is:
```
　client, addr = socket_server.accept()
　my_file = client.makefile(“rb”)
　
　reader = pa.RecordBatchStreamReader(my_file)
　talbe = reader.read_all()
　# raise ValueError
　df = table.to_pandas()  
```
    The reason for this problem is that the columns names of the table are 
['int', 'int']. How should I solve this problem?

Best regards,
