# TimeSformer (base-sized model, fine-tuned on Something Something v2) 

TimeSformer model pre-trained on [Something Something v2](https://developer.qualcomm.com/software/ai-datasets/something-something). It was introduced in the paper [TimeSformer: Is Space-Time Attention All You Need for Video Understanding?](https://arxiv.org/abs/2102.05095) by Tong et al. and first released in [this repository](https://github.com/facebookresearch/TimeSformer). 

Disclaimer: The team releasing TimeSformer did not write a model card for this model so this model card has been written by [fcakyon](https://github.com/fcakyon).

## Intended uses & limitations

You can use the raw model for video classification into one of the 174 possible Something Something v2 labels.

### How to use

Here is how to use this model to classify a video:

```python
from transformers import AutoImageProcessor, TimesformerForVideoClassification
import numpy as np
import torch

video = list(np.random.randn(8, 3, 224, 224))

processor = AutoImageProcessor.from_pretrained("fcakyon/timesformer-base-finetuned-ssv2")
model = TimesformerForVideoClassification.from_pretrained("fcakyon/timesformer-base-finetuned-ssv2")

inputs = processor(images=video, return_tensors="pt")

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

predicted_class_idx = logits.argmax(-1).item()
print("Predicted class:", model.config.id2label[predicted_class_idx])
```
