with CR line endings:
DeprecationWarning: 'U' mode is deprecated
with open(csvfile, mode='rU', newline='') as cf:
Traceback (most recent call last):

config_dict['has_header'] = csv.Sniffer().has_header(cf.read(10240))

header = next(rdr) # assume first row is header
_csv.Error: new-line character seen in unquoted field - do you need to open the
