Anthropic HH new dataset format repeats the prompt

[JubilantJerry]

With the new data format of Anthropic HH in v0.8.2 (for example, see https://huggingface.co/datasets/trl-internal-testing/hh-rlhf-trl-style vs. the older https://huggingface.co/datasets/trl-internal-testing/Anthropic-hh-rlhf-processed), I think the samples for DPO training end up repeating the first message of the chat. For example, if the original row of the dataset is:

prompt: "How do I program a robot?"
chosen: [ { "content": "How do I program a robot?", "role": "user" }, { "content": "Programming a robot requires some knowledge of programming. What kind of robot are you trying to program?", "role": "assistant" } ]

Then the processed sample (for chosen) will look like:

<s> How do I program a robot? user: How do I program a robot?

assistant: Programming a robot requires some knowledge of programming. What kind of robot are you trying to program?

Fully agree.

The current data processing code (e.g., tokenize_row function in DPOTrainer:
https://github.com/huggingface/trl/blob/1d0a7ea17b8055a6850970ab59a34709d8ca494d/trl/trainer/dpo_trainer.py#L716C9-L716C21) is incompatible with the new data format of https://huggingface.co/datasets/trl-internal-testing/hh-rlhf-trl-style.

----------------------------------------------- Print out the detailed tokenized data format (using the first data sample in Anthropic HH in v0.8.2 dataset for example) --------------------------------------------
Command:

tokenized_train_dataset = tokenize_row(train_dataset[0]) 
print(tokenized_train_dataset.keys()) 
# chosen part 
print(tokenized_train_dataset["chosen_input_ids"]) 
print(tokenized_train_dataset["chosen_attention_mask"]) 
print(tokenized_train_dataset["chosen_labels"]) 
print(tokenizer.decode(tokenized_train_dataset["chosen_input_ids"])) 

Execution results:
dict_keys(['chosen_input_ids', 'chosen_attention_mask', 'chosen_labels', 'rejected_input_ids', 'rejected_attention_mask', 'rejected_labels', 'prompt_input_ids', 'prompt_attention_mask’])

I believe the dataset still has this issue.
