Hi Guys! Can you tell me how can I get rid of those warnings in this code below?
I spend like 2 days already without any success. Even working example of any conversational pipeline would welcome.
1. The attention mask and the pad token id were not set. As a consequence, you may observe unexpected behavior. Please pass your input’s `attention_mask` to obtain reliable results.
2. Setting `pad_token_id` to `eos_token_id`:50256 for open-end generation.
A decoder-only architecture is being used, but right-padding was detected! For correct generation results, please set `padding_side='left'` when initializing the tokenizer.
```auto
from transformers import pipeline, Conversation
pipeline = pipeline(
"conversational", model=model, tokenizer=tokenizer,
max_new_tokens=150
)
conversation = Conversation(text = "Going to the movies tonight - any suggestions?")
print(conversation)
print(pipeline(conversation))
```

Hi, did you ever find a fix? Running into the same issue now. Thanks!

Hi! Can you provide the model id used and transformers version? I couldn’t reproduce it
