简介

这是一个基于 DINOv2 预训练权重的 ViT-Small 视觉模型，由 timm 库提供。它采用了 14 像素的 Patch 大小，核心优势在于其强大的自监督特征提取能力。不同于传统的分类模型，它更像是一个“通用视觉编码器”，能将图像转化为高质量的向量表示。对于中国开发者来说，该模型非常适合用于图像检索、相似度对比或作为下游任务（如目标检测、语义分割）的特征骨干网络。由于模型规模较小，推理速度快，且无需复杂微调即可在多种视觉任务中获得不错的基准效果，上手门槛极低。

核心亮点

  • 基于 DINOv2 自监督预训练，特征表达能力强
  • ViT-Small 架构，在性能与推理速度间取得平衡
  • 适用于图像检索、聚类及视觉特征提取场景
  • 兼容 timm 库，一行代码即可快速加载调用

Model Usage

Image Classification

python
from urllib.request import urlopen
from PIL import Image
import timm

img = Image.open(urlopen(
    'https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/beignets-task-guide.png'
))


model = timm.create_model('vit_small_patch14_reg4_dinov2.lvd142m', pretrained=True)
model = model.eval()


get model specific transforms (normalization, resize)

data_config = timm.data.resolve_model_data_config(model)
transforms = timm.data.create_transform(**data_config, is_training=False)

output = model(transforms(img).unsqueeze(0))  # unsqueeze single image into batch of 1


top5_probabilities, top5_class_indices = torch.topk(output.softmax(dim=1) * 100, k=5)

Image Embeddings

python
from urllib.request import urlopen
from PIL import Image
import timm

img = Image.open(urlopen(
    'https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/beignets-task-guide.png'
))


model = timm.create_model(
    'vit_small_patch14_reg4_dinov2.lvd142m',
    pretrained=True,
    num_classes=0,  # remove classifier nn.Linear
)
model = model.eval()


get model specific transforms (normalization, resize)

data_config = timm.data.resolve_model_data_config(model)
transforms = timm.data.create_transform(**data_config, is_training=False)

output = model(transforms(img).unsqueeze(0))  # output is (batch_size, num_features) shaped tensor


or equivalently (without needing to set num_classes=0)


output = model.forward_features(transforms(img).unsqueeze(0))
output is unpooled, a (1, 1374, 384) shaped tensor


output = model.forward_head(output, pre_logits=True)
output is a (1, num_features) shaped tensor
