V-JEPA 2
A frontier video understanding model developed by FAIR, Meta, which extends the pretraining objectives of VJEPA, resulting in state-of-the-art video understanding capabilities, leveraging data and model sizes at scale. The code is released in this repository.
Installation
To run V-JEPA 2 model, ensure you have installed the latest transformers:
pip install -U git+https://github.com/huggingface/transformers
Video classification code snippet
import torch
import numpy as np
from torchcodec.decoders import VideoDecoder
from transformers import AutoVideoProcessor, AutoModelForVideoClassification
device = "cuda" if torch.cuda.is_available() else "cpu"
# Load model and video preprocessor
hf_repo = "facebook/vjepa2-vitg-fpc32-384-diving48"
model = AutoModelForVideoClassification.from_pretrained(hf_repo).to(device)
processor = AutoVideoProcessor.from_pretrained(hf_repo)
# To load a video, sample the number of frames according to the model.
video_url = "https://huggingface.co/facebook/vjepa2-vitg-fpc32-384-diving48/resolve/main/sample/diving.mp4"
vr = VideoDecoder(video_url)
frame_idx = np.arange(0, model.config.frames_per_clip, 8) # you can define more complex sampling strategy
video = vr.get_frames_at(indices=frame_idx).data # frames x channels x height x width
# Preprocess and run inference
inputs = processor(video, return_tensors="pt").to(model.device)
with torch.no_grad():
outputs = model(**inputs)
logits = outputs.logits
print("Top 5 predicted class names:")
top5_indices = logits.topk(5).indices[0]
top5_probs = torch.softmax(logits, dim=-1).topk(5).values[0]
for idx, prob in zip(top5_indices, top5_probs):
text_label = model.config.id2label[idx.item()]
print(f" - {text_label}: {prob:.2f}")
Output:
Top 5 predicted class names:
- ['Forward', '35som', 'NoTwis', 'PIKE']: 0.49
- ['Forward', '25som', 'NoTwis', 'PIKE']: 0.13
- ['Forward', '25som', '1Twis', 'PIKE']: 0.13
- ['Forward', '35som', 'NoTwis', 'TUCK']: 0.10
- ['Forward', '25som', '2Twis', 'PIKE']: 0.04
