# TimeSformer (high-resolution variant, 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 TimesformerFeatureExtractor, TimesformerForVideoClassification
|
||||
import numpy as np
|
||||
import torch
|
||||
|
||||
video = list(np.random.randn(16, 3, 448, 448))
|
||||
|
||||
feature_extractor = TimesformerFeatureExtractor.from_pretrained("facebook/timesformer-hr-finetuned-ssv2")
|
||||
model = TimesformerForVideoClassification.from_pretrained("facebook/timesformer-hr-finetuned-ssv22")
|
||||
|
||||
inputs = feature_extractor(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])
|
||||
```
|
||||
|
||||
