Usage Examples

Using with Transformers (SafeTensors)

from transformers import Qwen2VLForConditionalGeneration, AutoProcessor
from PIL import Image
import torch

# Load model and processor
model_path = "E:/huggingface/qwen2.5-vl-7b-instruct"
model = Qwen2VLForConditionalGeneration.from_pretrained(
    model_path,
    torch_dtype=torch.float16,
    device_map="auto"
)
processor = AutoProcessor.from_pretrained("Qwen/Qwen2.5-VL-7B-Instruct")

# Load and process image
image = Image.open("your_image.jpg")
prompt = "Describe this image in detail."

# Prepare inputs
inputs = processor(
    text=prompt,
    images=image,
    return_tensors="pt"
).to("cuda")

# Generate response
output = model.generate(
    **inputs,
    max_new_tokens=512,
    temperature=0.7,
    do_sample=True
)

# Decode response
response = processor.decode(output[0], skip_special_tokens=True)
print(response)

Using with llama.cpp (GGUF)

# Q4_K_M quantized version (most efficient)
llama-cli \
  --model "E:/huggingface/qwen2.5-vl-7b-instruct/qwen2.5-vl-7b-instruct-abliterated-q4-k-m.gguf" \
  --image "your_image.jpg" \
  --prompt "What do you see in this image?" \
  --ctx-size 4096 \
  --n-gpu-layers 35 \
  --temp 0.7

# Q5_K_M quantized version (better quality)
llama-cli \
  --model "E:/huggingface/qwen2.5-vl-7b-instruct/qwen2.5-vl-7b-instruct-abliterated-q5-k-m.gguf" \
  --image "your_image.jpg" \
  --prompt "Analyze the objects and their relationships in this image." \
  --ctx-size 4096 \
  --n-gpu-layers 35 \
  --temp 0.7

Using with Ollama

Performance Tips

Optimization Strategies

1. Use Quantized Models: Q5_K_M or Q4_K_M formats provide excellent quality with lower VRAM usage
2. GPU Offloading: Use --n-gpu-layers parameter to maximize GPU utilization
3. Context Management: Keep context length reasonable (2048-4096) for faster inference
4. Batch Processing: Process multiple images in batches for efficiency
5. Temperature Control: Lower temperature (0.5-0.7) for factual descriptions, higher (0.8-1.0) for creative tasks

Memory Optimization

# Enable memory-efficient attention
model = Qwen2VLForConditionalGeneration.from_pretrained(
    model_path,
    torch_dtype=torch.float16,
    device_map="auto",
    use_flash_attention_2=True,  # Requires flash-attn installed
    low_cpu_mem_usage=True
)

Image Preprocessing

from PIL import Image

# Resize large images to reduce memory usage
def preprocess_image(image_path, max_size=1024):
    image = Image.open(image_path)
    image.thumbnail((max_size, max_size), Image.LANCZOS)
    return image

Abliteration Notice

⚠️ Important: This is an abliterated model variant with reduced safety restrictions. Key considerations:

• Uncensored Responses: The model may provide responses without typical safety refusals
• Research Use: Primarily intended for research, creative applications, and controlled environments
• Responsibility: Users are responsible for appropriate use and content filtering
• No Guarantees: Abliteration does not guarantee complete removal of all safety behaviors
• Legal Compliance: Ensure usage complies with local laws and regulations
