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 [READMEhttps://github.com/yjxiong/temporal-segment-networks#extract-frames-and-optical-flow-images)

####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. The reported accuracy is video-level testing results using 25 frames per video. Please follow the intructions provided to test your trained models and check the results
