In the example, the default epoch is 50. Please read our paper, and train 1000~2000 epochs for repruducing this work! I will not respond to such a lowly mistake.

The pre-trained models and benchmarks will be available in SimVPv2.

SimVPv2 is available on https://github.com/chengtan9907/SimVPv2, which performs better than SimVP (15.05 MSE on Moving MNIST) and is in the review process. If our work is helpful for your research, we would hope you give us a star and citation. Thanks!

This repository contains the implementation code for paper:

SimVP: Simpler yet Better Video Prediction
Zhangyang Gao, Cheng Tan, Lirong Wu, Stan Z. Li. In CVPR, 2022.

From CNN, RNN, to ViT, we have witnessed remarkable advancements in video prediction, incorporating auxiliary inputs, elaborate neural architectures, and sophisticated training strategies. We admire these progresses but are confused about the necessity: is there a simple method that can perform comparably well? This paper proposes SimVP, a simple video prediction model that is completely built upon CNN and trained by MSE loss in an end-to-end fashion. Without introducing any additional tricks and complicated strategies, we can achieve state-of-the-art performance on five benchmark datasets. Through extended experiments, we demonstrate that SimVP has strong generalization and extensibility on real-world datasets. The significant reduction of training cost makes it easier to scale to complex scenarios. We believe SimVP can serve as a solid baseline to stimulate the further development of video prediction.
