How to Use the Uncensored Qwen2.5-Coder-1.5B-Instruct Model

The Qwen2.5-Coder-1.5B-Instruct, particularly its uncensored version, is a powerful language model that can assist in various text generation tasks. This guide will walk you through the steps to effectively use this model in your applications, troubleshoot common issues, and understand the inner workings of the code.

What is Abliteration?

The uncensored model is created using a technique called abliteration. This process alters the model to remove certain biases or constraints, allowing it to generate more diverse responses. For a deeper understanding of what abliteration entails, check out this detailed article on Hugging Face.

Getting Started

To begin using this model, you need to set up your Python environment and load the necessary libraries. Follow these steps:

1. Install the transformers library from Hugging Face, if you haven’t already:

2. pip install transformers torch

3. Next, load the model and tokenizer as shown below:

from transformers import AutoModelForCausalLM, AutoTokenizer

# Load the model and tokenizer
model_name = "huihui-ai/Qwen2.5-Coder-1.5B-Instruct-abliterated"
model = AutoModelForCausalLM.from_pretrained(model_name, torch_dtype="auto", device_map="auto")
tokenizer = AutoTokenizer.from_pretrained(model_name)

Setting Up the Conversation

Now, let’s initialize the conversation context and allow for user input:

# Initialize conversation context
initial_messages = [
    {"role": "system", "content": "You are Qwen, created by Alibaba Cloud. You are a helpful assistant."}
]
messages = initial_messages.copy()  # Copy the initial conversation context

# Enter conversation loop
while True:
    user_input = input("User: ").strip()  # Get user input
    ...  # Additional logic goes here

Analogy to Understand Conversation Loop

Think of this code as hosting a dinner party. At the start of the evening, you set the table (initializing the conversation context). When your guests arrive (user input), you interact based on how they engage. If they leave or say something you didn’t expect, you adapt (keeping context or resetting). The model is like the chef in the kitchen, responding to every guest’s preference with a tailored dish!

Building the Chat

As the conversation progresses, the user can provide input, and the model will generate responses. The following code snippet enhances the interaction:

# Get user input
if user_input.lower() == "exit":
    print("Exiting chat.")
    break
...  # Additional checks and handling

Evaluations

Evaluating our model is crucial to understanding its performance and making necessary adjustments. Key metrics from recent evaluations of the model include:

• IF_Eval: 43.43 to 45.41
• MMLU Pro: 21.5 to 20.57
• TruthfulQA: 46.07 to 41.9

The evaluation script is included in the repository, so you can run your assessments as well.

Troubleshooting

If you encounter any issues while using the transformer library or the model itself, consider the following troubleshooting tips:

• Error in loading model: Ensure you have the correct model name and all required packages installed.
• Input errors: Always check that your input is not empty, as the model will respond with an error if it is.
• Conversation context not maintained: Review your loop logic to ensure you’re properly managing states.
