# VideoMAE-v2 (Large-sized model, Pretrained on UnlabeledHybrid-1M) 

VideoMAEv2-Large model pre-trained for 800 epochs in a self-supervised way on UnlabeldHybrid-1M dataset. It was introduced in the paper [[CVPR23]VideoMAE V2: Scaling Video Masked Autoencoders with Dual Masking](https://arxiv.org/abs/2203.12602) by Wang et al. and first released in [GitHub](https://github.com/OpenGVLab/VideoMAEv2). 


## Intended uses & limitations

You can use the raw model for video feature extraction.

### How to use

Here is how to use this model to extract a video feature:

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


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