What code was used for evaluating Fréchet Video Distance(FVD)?

[Maxlinn]

Hi hong and the whole THUDM team, thanks for your hard work and CogVideo seems really interesting!

In the "5.1 Machine Evaluation" section of your paper, you mentioned Inception Score(IS) was calculated using the official code of TGAN-v2, that's nice and handy. But i can't find out how Fréchet Video Distance(FVD) was evaluated. More specifically, which library or code did you choose for evaluating FVD? I carefully looked into your paper and codebase but didn't find some clue.

Did i miss something? Or could you please give me some hint? Thanks in advance!
