Frequently Asked Questions

Which platform is supported?

Currently, our modified Caffe toolbox and dense_flow toolbox only support Linux platform. You are welcome to make a PR if you manage to run them on Mac/Windows.

Data Preparation

####1. How can I generate the optical flow & the warped optical flow images?

Please see README

####2. Cannot compile the dense_flow toolbox Dense flow relies on an additional dependency: libzip. Please use your package manager to install it.

Training TSN

####1. The Caffe toolbox reports some file missing, what can I do? Perhaps the file lists need to be generated again. Please see README for how to do it.

Testing TSN

####1. Caffe reports way lower accuracies in on-the-fly validation than what you guys reported, what's wrong? Easy, there is nothing wrong. Numbers you see during training are just for monitoring the training process.

The reported numbers in the paper are the video-level testing results using 25 frames per video. Please follow the intructions provided to test your trained models and check the results
