show me full codes how to apply for the following model on the data frame df3 on column "body_text" to summarize the text in that column, import torch
import transformers
from transformers import LlamaTokenizer, LlamaForCausalLM, GenerationConfig, pipeline

tokenizer = LlamaTokenizer.from_pretrained("TheBloke/stable-vicuna-13B-HF")

model = LlamaForCausalLM.from_pretrained("TheBloke/stable-vicuna-13B-HF",
                                              load_in_8bit=True,
                                              device_map='auto',
                                              torch_dtype=torch.float16,
                                              low_cpu_mem_usage=True
                                              ) In your entire response, the letter e should appear less than 24.
