can't reproduce fid results

Hi, llamagen is a nice work, but i can't reproduce the fid by pretrained model. There are my settings, is there anything wrong?
```
args.seed = 0
args.cfg_scale = 2
args.top_k = 0
args.top_p = 1
args.cfg_interval=-1
args.temperature=1
```
I generate 50 imgs for each class and using llamagen-L24 model. The fid is 6.84 for me.
