Attribute Error

Hi, I am using MonoT5 model to rerank my own collection. However I am getting the following error:

Traceback (most recent call last):
  File "pygaggle/passaget5.py", line 100, in <module>
    reranked_total = reranker.rerank(query_total, texts)
  File "/usr/src/app/pygaggle/pygaggle/rerank/transformer.py", line 60, in rerank
    return_last_logits=True)
  File "/usr/local/lib/python3.6/dist-packages/torch/autograd/grad_mode.py", line 26, in decorate_context
    return func(*args, **kwargs)
  File "/usr/src/app/pygaggle/pygaggle/model/decode.py", line 27, in greedy_decode
    use_cache=True)
TypeError: prepare_inputs_for_generation() missing 1 required positional argument: 'encoder_outputs'
Exception ignored in: <bound method Buckets.__del__ of <tensorflow.python.eager.monitoring.ExponentialBuckets object at 0x7f4864fa5108>>

AttributeError: 'NoneType' object has no attribute TFE_MonitoringDeleteBuckets

My code is the following, and I have checked that query_total and texts variables are non-empty:

doc_passages = [p for p in doc_passages if p]
texts = [ Text(p, None, 0) for p in doc_passages]
               
query_total = Query(hand_expression_total)
print("Query total", query_total)
print("Texts", texts[0])
reranked_total = reranker.rerank(query_total, texts)
reranked_total.sort(key=lambda x: x.score, reverse=True)

Hi @MarcosFP97 which transformers version are you using?
pygaggle is currently using transformers==2.10.0
newer version of transformers may cause the error below.

TypeError: prepare_inputs_for_generation() missing 1 required positional argument: 'encoder_outputs'

we are working on update transformers dependency to 3.4.0 (#107) but before that could you double check if transformers==2.10.0?

Hi @MXueguang, that was the problem! I downgraded transformers to 2.10.0 and the error disappeared. I will wait to the new release to upgrade transformers version again. Thank you very much!
