🚀 VideoMAE-v2 (巨型模型，在UnlabeledHybrid-1M上预训练)

VideoMAE-v2是一个巨型模型，在UnlabeldHybrid-1M数据集上以自监督的方式进行了1200个轮次的预训练。该模型由Wang等人在论文[CVPR23]VideoMAE V2: Scaling Video Masked Autoencoders with Dual Masking中提出，并首次在GitHub上发布。

VideoMAE-v2模型可用于视频特征提取。以下是使用该模型提取视频特征的示例代码：

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)
