The default `SD 1.5` model?

[liusida]

I've started the docker and headed to the web GUI, but when I press "Queue Prompt", this error shows up:

Error occurred when executing CheckpointLoaderSimple:

I realized that the default SD 1.5 model is not there; instead, the default one is SD 2.1-unclip-small. I manually downloaded the default SD 1.5, and everything works. So I wonder why SD 2.1-unclip-small was chosen as the default? And why was I running into such an error?

This was fixed yesterday, just now I pushed a new image. The checkpoints folder will leave empty and people will aware. Models could be downloaded via ComfyUI-Manager or manually from https://civitai.com/ & https://huggingface.co/ & https://www.liblib.art/

Thanks for the quick response.

I think I might need to write my own ./storage/scripts/pre-start.sh to download whatever I need, right?

Is there a template or example that I can refer to for writing this script?

[YanWenKun]

As mentioned in #28, give a try to megapak !

But ./storage/scripts/pre-start.sh can do it too, for example:

#!/bin/bash

echo "[INFO] Downloading my favorite models..."

cd /home/runner/ComfyUI/models
aria2c \
  --input-file=/home/runner/scripts/download-my-fav-models.txt \
  --allow-overwrite=false \
  --auto-file-renaming=false \
  --continue=true \
  --max-connection-per-server=5

And ./storage/scripts/download-my-fav-models.txt :

A side note: batch-download from CivitAI sometimes reports error, so I prefer downloading from Huggingface, as you see in download.txt

Cool, thanks~
