Questions about details for reproducing, some of them are not noted in the paper. #71

The problem is about the fid-score on COCO2014CD. My fid is about 13, while the fid in paper is 5.8. The details for this part is not enough in paper. So it's really hard for reproducing.

So my questions can be concluded as following:

  1. Is the pretrained model downloaded from here? https://ommer-lab.com/files/latent-diffusion/nitro/txt2img-f8-large/model.ckpt

  2. Dropping probability for caption is 0.5 in github config file, and 0.1 in paper. Which one should i choose?

  3. As we all know, ldm resolution is 256. Is gligen finetuned on 256 or 512 ?

  4. While training, the warm-up is cosine or constant? Is 100,000 step enough for COCO?

  5. In UNet, only gate-attention is not freezed, right?

Are there any updates on this issue? I'm also curious which caption dropping rate to use for training (10% as in the paper or 50% as in the code.

why gligen is always output 512512, how to output 640480

gligen基于LDM和Stable-Diffusion这两个大模型训练，这两个模型的输出分辨率固定为512和256。如果你想直接输出640*480的，必须去找一个能输出同样分辨率的图像生成大模型，这很困难。所以我建议你采用裁剪+放缩的方式进行后处理。
