+# Qwen2-VL-2B Fine-tuned on ChartQA
+
+Fine-tuned version of Qwen2-VL-2B-Instruct on the ChartQA dataset for visual question answering on charts.
+
+## Model Details
+- **Base model:** Qwen/Qwen2-VL-2B-Instruct
+- **Fine-tuning:** LoRA (r=16, alpha=32, target: q/k/v/o projections)
+- **Dataset:** HuggingFaceM4/ChartQA (2000 train, 200 val samples)
+- **Training:** 1 epoch, lr=2e-4, T4 GPU on Kaggle
+- **Results:** Train Loss: 0.5040 | Val Loss: 0.6956
+
+## How to Use
+```python
+from transformers import AutoProcessor, Qwen2VLForConditionalGeneration
+from PIL import Image
+import torch
+
+model_id = "Devildarker6789/qwen2vl-chartqa"
+
+processor = AutoProcessor.from_pretrained(model_id, min_pixels=256*28*28, max_pixels=512*28*28)
+model = Qwen2VLForConditionalGeneration.from_pretrained(
+    model_id,
+    torch_dtype=torch.float16,
+    device_map="auto"
+)
+model.eval()
+
+image = Image.open("your_chart.png").convert("RGB")
+question = "What is the highest value in this chart?"
+
+messages = [{"role": "user", "content": [
+    {"type": "image", "image": image},
+    {"type": "text",  "text": question}
+]}]
+
+text = processor.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
+inputs = processor(text=[text], images=[image], return_tensors="pt").to(model.device)
+
+with torch.no_grad():
+    out = model.generate(**inputs, max_new_tokens=64, do_sample=False)
+
+print(processor.decode(out[0][inputs["input_ids"].shape[1]:], skip_special_tokens=True))
+```
+
