lack of some files

when I try to run python main.py --base configs/latent-diffusion/celebahq-ldm-vq-4_multistage224-256-192-128.yaml -t --gpus 0,an error occurs

Traceback (most recent call last):

it seems that i don't get the file "models/first_stage_models/vq-f4/model.ckpt",could tell me where to get it?

Sorry it was unclear. You can follow the original script in Latent Diffusion and find the links to the model: https://github.com/CompVis/latent-diffusion/blob/main/scripts/download_first_stages.sh
