text: Title: Can I know what is the size of the Kinetics 400 dataset used to reproduce the result in this repo?
  Body: There are many links in Kinetics that have expired. As as result, everyone might not be using the same Kinetics dataset. As a reference, the statistics of the Kinetics dataset used in PySlowFast can be found here, https://github.com/facebookresearch/video-nonlocal-net/blob/master/DATASET.md. However, I cannot seem to find similar information for gluoncv. Will you guys be sharing the statistics and the dataset used? I need the complete dataset to reproduce the result.
