How to get STAIR Actions V1.0

We provide a download script for STAIR Actions download.sh, which enables you to download both STAIR Actions (C) and (Y) at one time. We highly recommend that you will run the script on a storage with over 1TB space.

The download script uses the crawler included in ActivityNet repository to get YouTube videos. To run the crawler, you need to construct python environment, following this README. Additionally, you need to install git, ffmpeg and jq in advance to run the download script.

After the construction of the enviromnent, you can download STAIR Actions by just executing the following command.

$ bash download.sh

It will takes a few days until the end of the execution. Finally, STAIR Actions will be created in STAIR_Actions_[version]/ directory, where [version] is the version number of STAIR Actions to be downloaded. Note that some video clips will not be generated because some YouTube videos cannot be downloaded ater constructing this dataset.
