Issue while using IPEX-LLM optimized Mixtral model in Langchain agent creation

[tsantra]

Below code works when I am using Mixtral model from Ollama directly. But when I use the IPEX-LLM optimized Mixtral model, the tool does not work. This is an easy tool for testing functionality , which just prints the text file. While Ollama is able to print it, but when I use the IPEX-LLM optimized model, I get a different output (below)

Code:

from langchain.agents import AgentExecutor, create_react_agent from react_template import get_react_prompt_template from ipex_llm.langchain.llms import TransformersLLM from custom_tool import report_generator from langchain_community.llms import Ollama from custom_tool import report_generator

Get the prompt to use - you can modify this!

prompt = get_react_prompt_template()

llm = Ollama(model="mixtral", temperature=0)

llm = TransformersLLM.from_model_id( model_id= , model_kwargs={"temperature": 0, "max_length": 1024, "trust_remote_code": True}, )

llm.model.save_low_bit(low_bit_model_path) del llm

low_bit_llm = TransformersLLM.from_model_id_low_bit( model_id=low_bit_model_path, tokenizer_id= , model_kwargs={"temperature": 0, "max_length": 1024, "trust_remote_code": True} )

tools =[report_generator]

Construct the ReAct agent

agent = create_react_agent(low_bit_llm, tools, prompt)

Create an agent executor by passing in the agent and tools

agent_executor = AgentExecutor(agent=agent, tools=tools, verbose=False, handle_parsing_errors=True)

file_path = "./model_summary.txt" r = agent_executor.invoke({"input": file_path})

Code for tool:

from langchain.agents import tool @tool def report_generator(file_path: str) -> str: """ Reads a text file and prints the content of it.

Args:
    file_path (str): Path to the text file to be read.

Returns:
    str: The status that printing of the content is done.
"""

try:
    # Read the content of the text file
    with open(file_path, 'r') as file:
        content = file.read()
except FileNotFoundError:
    return "Error: The file was not found."
except Exception as e:
    return f"Error: An error occurred while reading the file. Details: {str(e)}"

print ("content is ", content)

return "printing is complete!"

Attached the log file. agent_ipex_log.txt

In the attached log, I saw a message "user provided a file path that does not exist or the file is empty" (see details below). Did you specify the correct file path?

Question: ./model_summary.txt Thought: The user wants me to read the content of the text file model_summary.txt. I can use the report_generator tool to do this. Action: report_generator Action Input: ./model_summary.txt ObservationInvalid or incomplete response The user provided a file path that does not exist or the file is empty. I will inform the user about this. Final Answer: The file at ./model_summary.txt does not exist or is empty. Please provide a valid file path.

And could you attach the code script and input file and tell us the exact command to execute the script? There're code formatting issues in your question and it's difficult to read your code and reproduce your result.

@shane-huang agent.zip

attached agent.zip , there are two scripts in the folder. The input file model_summary.txt is inside the folder.

Run command: python agent_ipex_test.py

Also, in the agent_ipex_test.py , please set the hf_model variable to <path where mistralai/Mixtral-8x7B-Instruct-v0.1 from hugginface is saved in your machine>

Also, about the issue "user provided a file path that does not exist or the file is empty" in the log file, yes the path is correct. And Ollama is being able to access the input file in the same path. The problem is , IPEX-LLM optimized model is not able to access it.

Please let me know if you have any questions. Thank you.

[shane-huang]

We will try reproduce your result.

I see. We have already reproduced the problem, and got a similar log compared to yours. We will get back to you once we got a solution.

@lzivan Could you please let me know if there is any update? thanks a lot!
