TensorRT-LLM: stop words can not work. how to set it

I set the stop words like this : stop_words_list = np.array([[“”]], dtype=object), when it passed to function _to_word_list_format(self, word_dict: List[List[str]]), the stop words become [[[ 1 2] [ 2 -1]]].
but when I pass a prompt to codeLlama，and set the “max_tokens” to 1024，the real output finished before 1024 ,like this:

The "</s> " means the output maybe finished but the engine still generating until the 1024 token is generated.

Thank you !
