WebbIntroduction. PyTorchVideo provides several pretrained models through Torch Hub. In this tutorial we will show how to load a pre trained video classification model in PyTorchVideo and run it on a test video. The PyTorchVideo Torch Hub models were trained on the Kinetics 400 [1] dataset. Available models are described in model zoo documentation. WebbLow frame rate Figure 1. A SlowFast network has a low frame rate, low temporal resolution Slow pathway and a high frame rate, higher temporal resolution Fast pathway. The Fast pathway is lightweight by using a fraction ( , e.g., 1/8) of channels. Lateral connections fuse them.
