Python Avro library can't read Avros made with Pig builtin AvroStorage

Using this script:
from avro import schema, datafile, io
import pprint
import sys
import json
field_id = None
Optional key to print
if (len(sys.argv) > 2):
field_id = sys.argv[2]
Test reading avros
rec_reader = io.DatumReader()
Create a 'data file' (avro file) reader
df_reader = datafile.DataFileReader(
open(sys.argv[1]),
rec_reader
)
the last line fails with:
Traceback (most recent call last):
