AttributeError: module 'snappy' has no attribute 'compress'

See original GitHub issue

macos, brew install of python3. then, after pandas,

# pip3 install snappy
snappy in /usr/local/lib/python3.7/site-packages (2.7)
...
# pip3 install fastparquet
Requirement already satisfied: fastparquet in /usr/local/lib/python3.7/site-packages (0.3.2)
...

the simple program

#!/usr/bin/env python3
from fastparquet import write
import csv
import pandas as pd

x= pd.read_csv( "test.csv" )  ## parq always writes to file, never to stdout
print( "reading was ok" )
parq.write_dataframe( x,  "./test.parq" )
print( "writing was ok" )

yields an error

  File "/usr/local/lib/python3.7/site-packages/fastparquet/compression.py", line 45, in <module>
    compressions['SNAPPY'] = snappy.compress
AttributeError: module 'snappy' has no attribute 'compress'

snappy was installed fine, partly via brew install snappy.

hope this helps.

If you have installed the snappy library try:

pip uninstall snappy python-snappy

and then reinstall:

pip install python-snappy

it worked for me.
