URL: https://github.com/apache/arrow/issues/7003


   I have tried versions 0.15.1, 0.16.0, 0.17.0. Same error on all. I've seen 
in other issues that co-installations of tensorflow and numpy might be causing 
issues. I have tensorflow==1.14.0 and numpy==1.16.4
   
   ```from pyarrow import parquet
    
   ~/python/lib/python3.6/site-packages/pyarrow/parquet.py in <module>
        32 import pyarrow as pa
        33 import pyarrow.lib as lib
   ---> 34 import pyarrow._parquet as _parquet
        35 
        36 from pyarrow._parquet import (ParquetReader, Statistics,  # noqa
   
   ~/python/lib/python3.6/site-packages/pyarrow/_parquet.pyx in init 
pyarrow._parquet()
   
   AttributeError: type object 'pyarrow._parquet.Statistics' has no attribute 
'__reduce_cython__'```
