Mevcut Hub özellikleri:
- BAIR Robot itme videoları ve KTH eylem video veri kümesi için modelleri vardır (bu ortak çalışma yalnızca BAIR kullanıyor olsa da)
- BAIR veri kümesi Hub'da zaten mevcut. Ancak, KTH videolarının kullanıcıların kendileri tarafından sağlanması gerekir.
- şimdilik sadece değerlendirme (video oluşturma)
- parti boyutu ve çerçeve boyutu sabit kodlanmıştır
