Installation on Apple Silicon

IMPORTANT While the web UI runs fine, there are still certain issues when running this fork on Apple Silicon. The only 2 samplers that work (at the time of writing this) are Euler and DPM2 - all others result in a black screen. Upscaling works, but only using the real-ESRGAN models.

First get the weights checkpoint download started - it's big:

Sign up at https://huggingface.co Go to the Stable diffusion diffusion model page Accept the terms and click Access Repository: Download sd-v1-4.ckpt (4.27 GB) and note where you have saved it (probably the Downloads folder)

1. brew install cmake protobuf rust
2. curl https://repo.anaconda.com/miniconda/Miniconda3-latest-MacOSX-arm64.sh -o Miniconda3-latest-MacOSX-arm64.sh
3. /bin/bash Miniconda3-latest-MacOSX-arm64.sh
4. git clone https://github.com/AUTOMATIC1111/stable-diffusion-webui
5. cd stable-diffusion-webui
6. Run the following commands one by one:

git clone https://github.com/CompVis/stable-diffusion.git repositories/stable-diffusion
 
git clone https://github.com/CompVis/taming-transformers.git repositories/taming-transformers

git clone https://github.com/sczhou/CodeFormer.git repositories/CodeFormer
    
git clone https://github.com/salesforce/BLIP.git repositories/BLIP

7. conda create --name web_ui python=3.10
8. conda activate web_ui
9. pip install -r requirements.txt
10. conda install pytorch torchvision torchaudio -c pytorch-nightly
11. At this point, move the downloaded sd-v1-4.ckpt file into stable-diffusion-webui/models/. You will know it's the right folder since there's a text file named Put Stable Diffusion checkpoints here.txt in it.
12. conda env config vars set PYTORCH_ENABLE_MPS_FALLBACK=1
13. python webui.py --precision full --no-half --opt-split-attention-v1

It is possible that after running webui.py you get error messages saying certain packages are missing. Install the missing package, go back to step 13 and repeat.

Common Errors

Error

ImportError: dlopen(.venv/lib/python3.10/site-packages/google/protobuf/pyext/_message.cpython-310-darwin.so, 0x0002): symbol not found in flat namespace (__ZN6google8protobuf15FieldDescriptor12TypeOnceInitEPKS1_)

Solution

Downgrade Protobuf using pip install protobuf==3.19.4
