🚀 VideoMAE-v2 (巨型模型，在UnlabeledHybrid-1M上預訓練)

VideoMAE-v2是一個巨型模型，在UnlabeldHybrid-1M數據集上以自監督的方式進行了1200個輪次的預訓練。該模型由Wang等人在論文[CVPR23]VideoMAE V2: Scaling Video Masked Autoencoders with Dual Masking中提出，並首次在GitHub上發佈。

🚀 快速開始

VideoMAE-v2模型可用於視頻特徵提取。以下是使用該模型提取視頻特徵的示例代碼：

from transformers import VideoMAEImageProcessor, AutoModel, AutoConfig
import numpy as np
import torch


config = AutoConfig.from_pretrained("OpenGVLab/VideoMAEv2-giant", trust_remote_code=True)
processor = VideoMAEImageProcessor.from_pretrained("OpenGVLab/VideoMAEv2-giant")
model = AutoModel.from_pretrained('OpenGVLab/VideoMAEv2-giant', config=config, trust_remote_code=True)


video = list(np.random.rand(16, 3, 224, 224))

# B, T, C, H, W -> B, C, T, H, W
inputs = processor(video, return_tensors="pt")
inputs['pixel_values'] = inputs['pixel_values'].permute(0, 2, 1, 3, 4)

with torch.no_grad():
  outputs = model(**inputs)
