I am trying to use fastparquet to open a file, but I get the error:

RuntimeError: Decompression 'SNAPPY' not available.  Options: ['GZIP', 'UNCOMPRESSED']

I have the following installed and have rebooted my interpreter:

python                    3.6.5                hc3d631a_2  
python-snappy             0.5.2                    py36_0    conda-forge
snappy                    1.1.7                hbae5bb6_3  
fastparquet               0.1.5                    py36_0    conda-forge

Everything downloaded smoothly. I didn't know if I needed snappy or python-snappy so I got one had no fix and got the other, still with no success. All related issues I have found are fixed when downloading snappy, but I am still getting this error with having two snappys! Any help would be appreciated.

Run:

pip install python-snappy
pip install pyarrow

It should do the trick.

I think you lack the pyarrow package.

If you have an error with pip, use conda instead (i.e., conda install python-snappy or if you still have errors conda install -c conda-forge python-snappy).
