The code is released [in this repository](https://github.com/facebookresearch/vjepa2).   ## Installation To run V-JEPA 2 model, ensure you have installed the latest transformers: ```bash pip install -U git+https://github.com/huggingface/transformers ``` ## Intended Uses V-JEPA 2 is intended to represent any video (and image) to perform video classification, retrieval, or as a video encoder for VLMs. ```python from transformers import AutoVideoProcessor, AutoModel hf_repo = "facebook/vjepa2-vitl-fpc64-256" model = AutoModel.from_pretrained(hf_repo) processor = AutoVideoProcessor.from_pretrained(hf_repo) ``` To load a video, sample the number of frames according to the model. For this model, we use 64. ```python import torch from torchcodec.decoders import VideoDecoder import numpy as np video_url = "https://huggingface.co/datasets/nateraw/kinetics-mini/resolve/main/val/archery/-Qz25rXdMjE_000014_000024.mp4" vr = VideoDecoder(video_url) frame_idx = np.arange(0, 64) # choosing some frames. here, you can define more complex sampling strategy video = vr.get_frames_at(indices=frame_idx).data # T x C x H x W video = processor(video, return_tensors="pt").to(model.device) with torch.no_grad(): video_embeddings = model.get_vision_features(**video) print(video_embeddings.shape) ``` To load an image, simply copy the image to the desired number of frames. ```python from transformers.image_utils import load_image image = load_image("https://huggingface.co/datasets/merve/coco/resolve/main/val2017/000000000285.jpg") pixel_values = processor(image, return_tensors="pt").to(model.device)["pixel_values_videos"] pixel_values = pixel_values.repeat(1, 16, 1, 1, 1) # repeating image 16 times with torch.no_grad(): image_embeddings = model.get_vision_features(pixel_values) print(image_embeddings.shape) ``` For more code examples, please refer to the V-JEPA 2 documentation. ### Citation ``` @techreport{assran2025vjepa2, title={V-JEPA~2: Self-Supervised Video Models Enable Understanding, Prediction and Planning}, author={Assran, Mahmoud and Bardes, Adrien and Fan, David and Garrido, Quentin and Howes, Russell and Komeili, Mojtaba and Muckley, Matthew and Rizvi, Ammar and Roberts, Claire and Sinha, Koustuv and Zholus, Artem and Arnaud, Sergio and Gejji, Abha and Martin, Ada and Robert Hogan, Francois and Dugas, Daniel and Bojanowski, Piotr and Khalidov, Vasil and Labatut, Patrick and Massa, Francisco and Szafraniec, Marc and Krishnakumar, Kapil and Li, Yong and Ma, Xiaodong and Chandar, Sarath and Meier, Franziska and LeCun, Yann and Rabbat, Michael and Ballas, Nicolas}, institution={FAIR at Meta}, year={2025} } ```
