Disk Space, GPU Usage, and Training Duration for Stage3

[myue22]

Hello! Thanks for your excellent work on the VideoChat2 model and code sharing.

I have a few questions regarding the "stage3" training phase of the model and hope you could help clarify:
Approximately how much disk space does the instruction_data dataset occupy during the "stage3" training phase?
How many GPUs did you use during this stage of training?
How long does it take to complete "stage3" training?

Thanks a lot in advance!
