Unable to run annotate.py

[TarunTater]

We are trying to run annotate.py but run into this error :

  File "annotate.py", line 164, in <module>
    fout=os.path.join(args.dout, split) + '.jsonl')
  File "annotate.py", line 132, in process_examples
    a = annotate_example(d, tables[d['table_id']])
  File "annotate.py", line 40, in annotate_example
    ann['question'] = annotate(example['question'])
  File "annotate.py", line 24, in annotate
    for s in client.annotate(sentence):
TypeError: 'Document' object is not iterable
[Thread-0] INFO CoreNLP - CoreNLP Server is shutting down.```

We have tried python3.6 with stanza 1.1 and tensorflow 1.4 as mentioned. Even tried downgrading stanza as mentioned here : 
https://github.com/salesforce/WikiSQL/issues/66 . But that creates other dependency issues. Can you please provide a list of requirements with versions which work or maybe a dockerfile. or any ideas on how to fix this error?
