# **Qwen2-VL-OCR2-2B-Instruct [ VL / OCR ]**
|
||||
|

|
||||
|
||||
# **Qwen2-VL-OCR2-2B-Instruct**
|
||||
|
||||
The **Qwen2-VL-OCR2-2B-Instruct** model is a fine-tuned version of **Qwen/Qwen2-VL-2B-Instruct**, tailored for tasks that involve **Optical Character Recognition (OCR)**, **English language understanding**, and **math problem solving with LaTeX formatting**. This model integrates a conversational approach with visual and textual understanding to handle multi-modal tasks effectively.
|
||||
|
||||
> [!note]
|
||||
> previous version https://huggingface.co/prithivMLmods/Qwen2-VL-OCR-2B-Instruct
|
||||
|
||||
#### Key Enhancements:
|
||||
|
||||
* **SoTA understanding of images of various resolution & ratio**: Qwen2-VL achieves state-of-the-art performance on visual understanding benchmarks, including MathVista, DocVQA, RealWorldQA, MTVQA, etc.
|
||||
|
||||
* **Understanding videos of 20min+**: Qwen2-VL can understand videos over 20 minutes for high-quality video-based question answering, dialog, content creation, etc.
|
||||
|
||||
* **Agent that can operate your mobiles, robots, etc.**: With the abilities of complex reasoning and decision-making, Qwen2-VL can be integrated with devices like mobile phones, robots, etc., for automatic operation based on visual environment and text instructions.
|
||||
|
||||
* **Multilingual Support**: To serve global users, besides English and Chinese, Qwen2-VL now supports the understanding of texts in different languages inside images, including most European languages, Japanese, Korean, Arabic, Vietnamese, etc.
|
||||
|
||||
### How to Use
|
||||
|
||||
```python
|
||||
from transformers import Qwen2VLForConditionalGeneration, AutoTokenizer, AutoProcessor
|
||||
from qwen_vl_utils import process_vision_info
|
||||
|
||||
# default: Load the model on the available device(s)
|
||||
model = Qwen2VLForConditionalGeneration.from_pretrained(
|
||||
"prithivMLmods/Qwen2-VL-OCR2-2B-Instruct", torch_dtype="auto", device_map="auto"
|
||||
)
|
||||
|
||||
# We recommend enabling flash_attention_2 for better acceleration and memory saving, especially in multi-image and video scenarios.
|
||||
# model = Qwen2VLForConditionalGeneration.from_pretrained(
|
||||
# "prithivMLmods/Qwen2-VL-OCR2-2B-Instruct",
|
||||
# torch_dtype=torch.bfloat16,
|
||||
# attn_implementation="flash_attention_2",
|
||||
# device_map="auto",
|
||||
# )
|
||||
|
||||
# default processor
|
||||
processor = AutoProcessor.from_pretrained("prithivMLmods/Qwen2-VL-OCR2-2B-Instruct")
|
||||
|
||||
# The default range for the number of visual tokens per image in the model is 4-16384. You can set min_pixels and max_pixels according to your needs, such as a token count range of 256-1280, to balance speed and memory usage.
|
||||
# min_pixels = 256*28*28
|
||||
# max_pixels = 1280*28*28
|
||||
# processor = AutoProcessor.from_pretrained("Qwen/Qwen2-VL-2B-Instruct", min_pixels=min_pixels, max_pixels=max_pixels)
|
||||
|
||||
messages = [
|
||||
{
|
||||
"role": "user",
|
||||
"content": [
|
||||
{
|
||||
"type": "image",
|
||||
"image": "https://qianwen-res.oss-cn-beijing.aliyuncs.com/Qwen-VL/assets/demo.jpeg",
|
||||
},
|
||||
{"type": "text", "text": "Describe this image."},
|
||||
],
|
||||
}
|
||||
]
|
||||
|
||||
# Preparation for inference
|
||||
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")
|
||||
|
||||
# Inference: Generation of the output
|
||||
generated_ids = model.generate(**inputs, max_new_tokens=128)
|
||||
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
|
||||
)
|
||||
print(output_text)
|
||||
```
|
||||
### Buffering Output
|
||||
```python
|
||||
buffer = ""
|
||||
for new_text in streamer:
|
||||
buffer += new_text
|
||||
# Remove <|im_end|> or similar tokens from the output
|
||||
buffer = buffer.replace("<|im_end|>", "")
|
||||
yield buffer
|
||||
```
|
||||
### **Key Features**
|
||||
|
||||
1. **Vision-Language Integration:**
|
||||
- Combines **image understanding** with **natural language processing** to convert images into text.
|
||||
|
||||
2. **Optical Character Recognition (OCR):**
|
||||
- Extracts and processes textual information from images with high accuracy.
|
||||
|
||||
3. **Math and LaTeX Support:**
|
||||
- Solves math problems and outputs equations in **LaTeX format**.
|
||||
|
||||
4. **Conversational Capabilities:**
|
||||
- Designed to handle **multi-turn interactions**, providing context-aware responses.
|
||||
|
||||
5. **Image-Text-to-Text Generation:**
|
||||
- Inputs can include **images, text, or a combination**, and the model generates descriptive or problem-solving text.
