Here we skip some special modules that can't be quantized properly bnb_config = BitsAndBytesConfig( load_in_4bit=True, bnb_4bit_use_double_quant=True, bnb_4bit_quant_type="nf4", bnb_4bit_compute_dtype=torch.float16, )
Simply take-off the quantization_config arg if you want to load the original model model = AutoModelForVision2Seq.from_pretrained( model_id, quantization_config=bnb_config, torch_dtype=torch.float16, device_map="auto") print(model)
processor = AutoProcessor.from_pretrained(model_id)
messages = [ {

"content": [

{"type": "image"},
{"type": "text", "text": "告诉我图片中的舌象指标有哪些"}
]
}
]
text = processor.apply_chat_template(messages, add_generation_prompt=True)
inputs = processor(text=[text.strip()], images=[image], return_tensors="pt", padding=True)
generated_ids = model.generate(**inputs, max_new_tokens=512)
generated_texts = processor.batch_decode(generated_ids[:, inputs["input_ids"].size(1):], skip_special_tokens=True)
===== 结果 ====================
客户提问： 请描述这张图片中的舌象细分类别。
客户舌图： <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=494x521 at 0x7F5D32BDBC10>
舌图15类标签： 绛_舌胖_有齿痕_有裂纹_有点刺_无瘀斑_无瘀点_无老嫩_无歪斜_黄_厚苔_无腐苔_有腻苔_润_无剥脱
大模型识别结果： ['淡红_舌胖_有齿痕_有裂纹_有点刺_无瘀斑_无瘀点_无老嫩_无歪斜_白_厚苔_无腐苔_有腻苔_润_无剥脱']
这里呈现的模型，是一个精度低的模型的视觉多模态模型的能力演示，
