Evaluation results different from the results from the paper

[peterw2333]

I ran the evaluation script for the provided checkpoint and found the results a bit different from the paper-reported results.
Especially, the FID and R-precision are higher, but the MultiModality and Multimodal Distance are significantly lower compared to the reported results. What could the reason for this discrepancy be?

The evaluation results from the checkpoint:

========== MM Distance Summary ==========

---> [InterGen] Mean: 3.7990 CInterval: 0.0022

me too, especially MM Distance, the groundtruth in paper is 3.75 but in eval output is 3.78, do anyone knows why?
I use 2*4090
