https://github.com/huggingface/transformers/blob/v4.46.1/src/transformers/cache_utils.py#L319

This Is related to this part of the faulty code:

parler-tts/parler_tts/modeling_parler_tts.py

Lines 3290 to 3297 in d108732

	cache_kwargs = {
	"config": self.config.decoder,
	"max_batch_size": max_batch_size,
	"max_cache_len": max_cache_len,
	"device": self.device,
	"dtype": cache_dtype,
	}
	self._cache = cache_cls(**cache_kwargs)

when testing on this snippet:
https://github.com/huggingface/parler-tts/blob/main/INFERENCE.md#compilation

Only need to fix the name from max_batch_size to batch_size, can open the PR too if needed
