Deutsch to English Translation Model by Google doesn't work anymore...
Hi, the model in: https://huggingface.co/google/bert2bert_L-24_wmt_de_en doesn't work anymore. It seems that the library has changed a lot since the model was added, therefore the classes themselves seem to have changed in names etc. 
Can anyone tell me how could I apply with the current library functionality?
Thanks in advance! :) 
Do you want to post the full error message? (and the information asked in the issue template)<|||||>These models have been added last months, so they shouldn't have changed much. The full issue template filled would be very helpful here!<|||||>This is the error: 
ValueError: Unrecognized model identifier: bert-generation.

Using exactly the code appearing in the link I passed:
```python
from transformers import AutoTokenizer, AutoModelForSeq2SeqLM

tokenizer = AutoTokenizer.from_pretrained("google/bert2bert_L-24_wmt_de_en", pad_token="<pad>", eos_token="</s>", bos_token="<s>")
model = AutoModelForSeq2SeqLM.from_pretrained("google/bert2bert_L-24_wmt_de_en")

sentence = "Willst du einen Kaffee trinken gehen mit mir?"

input_ids = tokenizer(sentence, return_tensors="pt", add_special_tokens=False).input_ids
output_ids = model.generate(input_ids)[0]
print(tokenizer.decode(output_ids, skip_special_tokens=True))
```

Transformers version: 3.1.0
<|||||>@patrickvonplaten what should be done here? The `BertGeneration` model cannot be loaded directly through the `AutoModelForSeq2SeqLM` auto-model, can it?<|||||>Then how could I load it?
<|||||>Hey @alexvaca0 - the google/encoder-decoder models were released in transformers 3.2.0 => so you will have to update your transformers version for it :-) It should then work as expected.<|||||>Ohhh so sorry, my bad :( Thanks a lot for the quick response! :) <|||||>I think this may not have been fully resolved? I'm getting a simmilar error:
