Llama 2 repeats its prompt as output without answering the prompt
I followed the Huggingface instructions (Llama 2 is here - get it on Hugging Face) but I cannot get a proper output from Llama 2. It keeps repeating the prompt without giving an output. Inputting a simple prompt without system prompt does work but for the purpose I’ll be using the model, I need to give a system prompt.This is my code:tokenizer = AutoTokenizer.from_pretrained("meta-llama/Llama-2-7b-hf", use_fast = True) 
base_model = "meta-llama/Llama-2-7b-hf"

model = AutoModelForCausalLM.from_pretrained(base_model, low_cpu_mem_usage=True, return_dict=True, torch_dtype=torch.float16, device_map = "auto")

prompt = """ <s>[INST] <<SYS>>

Try to setrepetition_penalry=1.2or ‘top_p=0.95’, or ‘temperature=0.8’.Experiment with these parameters. Try a combination of them.
