| ## HOW TO USE |
|
|
| 模型的使用方案与Qwen2-VL-2B-Instruct一致:https://huggingface.co/Qwen/Qwen2-VL-2B-Instruct#quickstart |
|
|
| ``` |
| # pip install qwen-vl-utils |
| |
| 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( |
| "Qwen/Qwen2-VL-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( |
| # "Qwen/Qwen2-VL-2B-Instruct", |
| # torch_dtype=torch.bfloat16, |
| # attn_implementation="flash_attention_2", |
| # device_map="auto", |
| # ) |
| |
| # default processer |
| processor = AutoProcessor.from_pretrained("Qwen/Qwen2-VL-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) |
| |
| ``` |
