PySlowFast is an open source video understanding codebase from FAIR that provides state-of-the-art video classification models, including papers "SlowFast Networks for Video Recognition", and "Non-local Neural Networks".
The goal of PySlowFast is to provide a high-performance, light-weight pytorch codebase provides state-of-the-art video backbones for video understanding research on different tasks (classification, detection, and etc). It is designed in order to support rapid implementation and evaluation of novel video research ideas. PySlowFast includes implementations of the following backbone network architectures:
- SlowFast
- SlowOnly
- C2D
- I3D
- Non-local Network
PySlowFast is released in conjunction with our ICCV 2019 Tutorial.
PySlowFast is released under the Apache 2.0 license.
We provide a large set of baseline results and trained models available for download in the PySlowFast Model Zoo.
Please find installation instructions for PyTorch and PySlowFast in INSTALL.md. You may follow the instructions in DATASET.md to prepare the datasets.
Follow the example in GETTING_STARTED.md to start playing video models with PySlowFast.
