1 week ago I think your problem is because of this line.
llama_new_context_with_model: n_ctx = 512
You have to set n_ctx=0 when you load your model.
I think of n_ctx as a limit on the total number of input and output tokens.
from llama_cpp import Llama
llm = Llama(model_path=model_path,
n_ctx=0, # If 0, it sets a limit on the total number of input and output tokens for the model.
)
All requests end with 'finish_reason': 'length' when the max_tokens=-1 parameter is set. What could be the problem?
