模型详情

⚠️ 重要提示

该模型有48个块，我们发现使用倒数第四块后的输出对多模态大语言模型（MLLM）效果最佳。因此，在使用此模型构建MLLM时，请使用倒数第四层的特征。

🚀 快速开始

⚠️ 重要提示

根据我们的经验，InternViT V2.5系列更适合构建多模态大语言模型，而非传统的计算机视觉任务。

基础用法

import torch
from PIL import Image
from transformers import AutoModel, CLIPImageProcessor

model = AutoModel.from_pretrained(
    'OpenGVLab/InternViT-6B-448px-V1-0',
    torch_dtype=torch.bfloat16,
    low_cpu_mem_usage=True,
    trust_remote_code=True).cuda().eval()

image = Image.open('./examples/image1.jpg').convert('RGB')

image_processor = CLIPImageProcessor.from_pretrained('OpenGVLab/InternViT-6B-448px-V1-0')

pixel_values = image_processor(images=image, return_tensors='pt').pixel_values
pixel_values = pixel_values.to(torch.bfloat16).cuda()

outputs = model(pixel_values)
