I found the solution:
for those using python module 'csv' to read the file, make sure you use it like this :
Code:
spamreader = csv.reader(csvfile, delimiter='\t')
and not like this:
Code:
spamreader = csv.reader(csvfile, delimiter='\t', quotechar='|')
Also you will need to add this line atfer the import:
Code:
csv.field_size_limit(sys.maxsize)
Best,
