I'm not sure whether some components are not downloaded

To download only benchmarks of social interaction and hands&objects, I used the command below.
python -m ego4d.cli.cli --output_directory="./ego4d_data" --datasets full_scale annotations --metadata --version v2 --benchmarks HO S
However, these files are all I got.

I can’t find any related video files and etc. Is the command above is a wrong usage?

Please use --benchmarks av fho instead. This will download the appropriate files for you.
