How to Use the Qwen2-VL-7B-Instruct Abliterated Model

If you’re looking to harness the power of the uncensored Qwen2-VL-7B-Instruct model in your applications, you’re in the right place! This article will guide you through the steps needed to successfully implement this text-generation model using the Hugging Face transformers library. Let’s dive into it!

Understanding the Qwen2-VL-7B-Instruct Model

This model serves as an enhanced version of the original Qwen2-VL-7B-Instruct, employing a technique known as abliteration. This process allows for more flexibility in text generation. Special thanks to @FailSpy for providing the code and technique behind this amazing model.

Setting Up Your Environment

Before you can start using the model, you must ensure that you have the right environment set up.

• Install the Hugging Face transformers library if you haven’t done so already:

pip install transformers

Loading the Model

Now that your environment is ready, let’s look at how to load the Qwen2-VL-7B-Instruct model in Python:

from transformers import Qwen2VLForConditionalGeneration, AutoProcessor
from qwen_vl_utils import process_vision_info

model = Qwen2VLForConditionalGeneration.from_pretrained(
    "huihui-aiQwen2-VL-7B-Instruct-abliterated", torch_dtype="auto", device_map="auto"
)

processor = AutoProcessor.from_pretrained("huihui-aiQwen2-VL-7B-Instruct-abliterated")

Using the Model

To use the model effectively, you will need to prepare your inputs – such as images and text requests. Consider the following code snippet:

image_path = "tmptest.png"
messages = [
    {"role": "user", "content": [
        {"type": "image", "image": f"file:{image_path}"},
        {"type": "text", "text": "Please describe the content of the photo in detail."},
    ]}
]

text = processor.apply_chat_template(
    messages, tokenize=False, add_generation_prompt=True
)

image_inputs, video_inputs = process_vision_info(messages)

inputs = processor(
    text=[text],
    images=image_inputs,
    videos=video_inputs,
    padding=True,
    return_tensors="pt",
)
inputs = inputs.to("cuda")

Generating the Output

Once the inputs are prepared, you can generate text by executing the following code:

generated_ids = model.generate(**inputs, max_new_tokens=256)
generated_ids_trimmed = [out_ids[len(in_ids):] for in_ids, out_ids in zip(inputs.input_ids, generated_ids)]
output_text = processor.batch_decode(
    generated_ids_trimmed, skip_special_tokens=True, clean_up_tokenization_spaces=False
)
output_text = output_text[0]
print(output_text)

Understanding the Process: An Analogy

Think of the Qwen2-VL-7B-Instruct model like an AI chef preparing a gourmet meal. Just as a chef gathers fresh ingredients (images and prompts), they follow a recipe (the model’s configuration and processor) to whip up a delightful dish (the text output). Each component — from the pristine ingredients to the timing of flavors — plays a crucial role in creating a masterpiece. Similarly, your careful input selection and usage of this model enrich the generated result!

Troubleshooting Tips

If you encounter issues while using the model, here are some tips to help you resolve them:

• Ensure you have the latest version of the transformers library installed.
• Check that your CUDA setup is correct if you are using GPU support.
• Confirm the image path and format are valid.
