mistral-7B-navigation-new-instructions

Model Description

llama2-navigation is a Larage Language Model (LLM) that is a fine-tuned version of mistralai/Mistral-7B-Instruct-v0.2. This model aims to provide navigation instructions given knowledge.

The model was fine-tuned with Lora and custom training data(voxreality/navigation_intructions_v2). For more details about the model's use case, you can find the code at the following link:

How to Get Started with the Model

Below you can find an example of model usage:

from transformers import AutoTokenizer, AutoModelForCausalLM, GenerationConfig, pipeline
from langchain import HuggingFacePipeline, PromptTemplate
from langchain.chains import LLMChain

model_name = "voxreality/mistral-7B-navigation-new-instructions"

user_msg = "I need to go to the social area."
knowledge = "start, turn left, crossing yellow sphere left, arrive wall opening, turn left, turn right, pass corridor, crossing magenta sphere left, arrive conference room, finish"

tokenizer = AutoTokenizer.from_pretrained(model_name, use_fast=True)
model = AutoModelForCausalLM.from_pretrained(model_name, torch_dtype=torch.float16, trust_remote_code=True, device_map="auto")

generation_config = GenerationConfig.from_pretrained(model_name)
generation_config.max_new_tokens = 1024
generation_config.temperature = 0.0001
generation_config.top_p = 0.95
generation_config.do_sample = True
generation_config.repetition_penalty = 1.15

text_pipeline = pipeline("text-generation", model=model, tokenizer=tokenizer, generation_config=generation_config)
llm = HuggingFacePipeline(pipeline=text_pipeline, model_kwargs={"temperature": 0})

text_pipeline = pipeline(
    "text-generation",
    model=model,
    tokenizer=tokenizer,
    generation_config=generation_config)

model = HuggingFacePipeline(pipeline=text_pipeline, model_kwargs={"temperature": 0})

prompt = textwrap.dedent("""
