# TimeSformer (base-sized model, fine-tuned on Kinetics-600)
|
|
|
|
TimeSformer model pre-trained on [Kinetics-600](https://www.deepmind.com/open-source/kinetics). 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 600 possible Kinetics-600 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("facebook/timesformer-base-finetuned-k600")
|
|
model = TimesformerForVideoClassification.from_pretrained("facebook/timesformer-base-finetuned-k600")
|
|
|
|
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])
|
|
```
|
|
|
