whether past_key_values can be obtained

Hi there.
I'm trying to combine chat.petals.dev with streaming-llm (https://github.com/mit-han-lab/streaming-llm).

However, when streaming-llm needs the output.past_key_values, I found that petals returns [RemotePastKeyValues].

And the annotation says 'A mock class representing the fact that `past_key_values` do exist but are stored on remote servers.'.

SO, I wonder if there is any way to get the real value of 'past_key_values'.
