How can I open a .snappy.parquet file in python?

问题

How can I open a .snappy.parquet file in python 3.5? So far, I used this code:

import numpy
import pyarrow

filename = "/Users/T/Desktop/data.snappy.parquet" 
df = pyarrow.parquet.read_table(filename).to_pandas()

But, it gives this error:

AttributeError: module 'pyarrow' has no attribute 'compat'

P.S. I installed pyarrow this way:

pip install pyarrow

回答1:

The error AttributeError: module 'pyarrow' has no attribute 'compat' is sadly a bit misleading. To execute the to_pandas() function on a pyarrow.Table instance you need pandas installed. The above error is a sympton of the missing requirement.

pandas is a not a hard requirement of pyarrow as most of its functionality is usable with just Python built-ins and NumPy. Thus users of pyarrow which include pandas can work with it without needing to have pandas pre-installed.
