Welcome, AI enthusiasts! Are you ready to dive into the dynamic world of AI model interactions? In this article, we will guide you through the process of using the Qwen2.5-Coder-7B-Instruct model, specifically its uncensored version, which utilizes the fascinating technique of abliterated models. Let’s get started!

What is the Qwen2.5-Coder-7B-Instruct Model?

The Qwen2.5-Coder-7B-Instruct is a cutting-edge language model that has been designed for various text generation applications. This particular version is uncensored and has gone through a process called abliteration, which enhances the model’s capabilities while ensuring safety during user interactions. For a detailed explanation of this technique, you might want to check out this article.

How to Set Up and Use the Model

To start using the Qwen2.5 model in your applications, follow these steps:

• Ensure you have the required libraries installed. You will need the transformers library by Hugging Face.
• Load the model and its tokenizer using the code snippet below.

from transformers import AutoModelForCausalLM, AutoTokenizer

# Load the model and tokenizer
model_name = 'huihui-ai/Qwen2.5-Coder-7B-Instruct-abliterated'
model = AutoModelForCausalLM.from_pretrained(model_name, torch_dtype='auto', device_map='auto')
tokenizer = AutoTokenizer.from_pretrained(model_name)

# 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
    if user_input.lower() == 'exit':
        print('Exiting chat.')
        break
    if user_input.lower() == 'clean':
        messages = initial_messages.copy()  # Reset conversation context
        print('Chat history cleared. Starting a new conversation.')
        continue
    if not user_input:
        print('Input cannot be empty. Please enter something.')
        continue

    messages.append({'role': 'user', 'content': user_input})  # Add user input to the conversation
    text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)  # Prepare chat template
    model_inputs = tokenizer([text], return_tensors='pt').to(model.device)  # Prepare input for the model
    generated_ids = model.generate(**model_inputs, max_new_tokens=8192)  # Generate response from model
    generated_ids = [output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)]  # Clean outputs
    response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]  # Decode the generated response
    messages.append({'role': 'assistant', 'content': response})  # Add the model's response to the conversation
    print(f'Qwen: {response}')  # Print the model's response

Explaining the Code: A Journey Through a Conversation

Think of the code above as a well-orchestrated play where each actor has a unique role. The model functions as your main character, ready to engage with the audience (the user).

• The initial_messages are like the opening scene, introducing the character Qwen to the audience, establishing context and setting expectations.
• The while True loop represents the continuous flow of the conversation, akin to a live dialogue that keeps evolving.
• Each user input is treated like a cue for the main character, prompting responses, and depending on the user’s directives (like ‘exit’ or ‘clean’), the script adjusts the play’s direction accordingly.
• Finally, the model generates a response, providing a resolution to the cues given by the audience, ensuring an engaging experience.

Troubleshooting Tips

If you encounter any issues while using the Qwen model, consider the following troubleshooting strategies:

• Model Loading Issues: Ensure that you’ve specified the correct model name and that your internet connection is stable.
• Input Formatting: Check if your inputs are formatted correctly. Remember, an empty input won’t be processed.
• Performance Problems: If the model is slow or unresponsive, make sure your device has adequate resources, or try reducing max_new_tokens in the model.generate() method.
