error: answer_choices and target keys

[meixide]

1. The value for answer_choices is a string representation of a list, which is not the expected format for the tokenizer. The tokenizer expects a list of strings or a list of lists of strings.

To fix this, we need to convert the string representation of the list into an actual list. We can use the ast.literal_eval function from the ast module to safely evaluate the string as a Python literal in encoder_decoder_functions.py:

if key == "answer_choices":
                # Convert string representation of list to actual list
                text = [item for sublist in ast.literal_eval(batch[key][0]) for item in sublist]
            else:
                text = batch[key]

2. The target key contains a list with a single integer element [1], which is not a valid input type for the tokenizer. The tokenizer expects a string, a list of strings, or a list of lists of strings.
   To fix this, we need to ensure that the target key is handled appropriately. Since target is likely a label, we might not need to tokenize it in the same way as input and answer_choices. We have to skip tokenizing target or handle it differently in encoder_decoder_functions.py:

keys_to_tokenize = ["input", "answer_choices"]
...

# Handle target separately if needed if "target" in batch: tokenized_batch["target"] = batch["target"]
