# Stable-Diffusion-Burn
|
|
|
|
Stable-Diffusion-Burn is a Rust-based project which ports the V1 stable diffusion model into the deep learning framework, Burn. This repository is licensed under the MIT Licence.
|
|
|
|
## How To Use
|
|
|
|
### Step 1: Download the Model and Set Environment Variables
|
|
|
|
Start by downloading the SDv1-4.bin model provided on HuggingFace.
|
|
|
|
```bash
|
|
wget https://huggingface.co/Gadersd/Stable-Diffusion-Burn/resolve/main/V1/SDv1-4.bin
|
|
```
|
|
|
|
### Step 2: Run the Sample Binary
|
|
|
|
Invoke the sample binary provided in the rust code. By default, torch is used. The WGPU backend is unstable for SD but may work well in the future as burn-wpu is optimized.
|
|
|
|
```bash
|
|
# torch (at least 6 GB VRAM, possibly less)
|
|
export TORCH_CUDA_VERSION=cu113
|
|
# Arguments: <model_type(burn or dump)> <model> <unconditional_guidance_scale> <n_diffusion_steps> <prompt> <output_image>
|
|
cargo run --release --bin sample burn SDv1-4 7.5 20 "An ancient mossy stone." img
|
|
|
|
# wgpu (UNSTABLE)
|
|
# Arguments: <model_type(burn or dump)> <model> <unconditional_guidance_scale> <n_diffusion_steps> <prompt> <output_image>
|
|
cargo run --release --features wgpu-backend --bin sample burn SDv1-4 7.5 20 "An ancient mossy stone." img
|
|
```
|
|
|
|
This command will generate an image according to the provided prompt, which will be saved as 'img0.png'.
|
|
|
|
|
|
|
|
### Optional: Extract and Convert a Fine-Tuned Model
|
|
|
|
If users are interested in using a fine-tuned version of stable diffusion, the Python scripts provided in this project can be used to transform a weight dump into a Burn model file. Note: the tinygrad dependency should be installed from source rather than with pip.
|
|
|
|
```bash
|
|
# Step into the Python directory
|
|
cd python
|
|
|
|
# Download the model, this is just the base v1.4 model as an example
|
|
wget https://huggingface.co/CompVis/stable-diffusion-v-1-4-original/resolve/main/sd-v1-4.ckpt
|
|
|
|
# Extract the weights
|
|
CPU=1 python3 dump.py sd-v1-4.ckpt
|
|
|
|
# Move the extracted weight folder out
|
|
mv params ..
|
|
|
|
# Step out of the Python directory
|
|
cd ..
|
|
|
|
# Convert the weights into a usable form
|
|
cargo run --release --bin convert params SDv1-4
|
|
```
|
|
|
|
The binaries 'convert' and 'sample' are contained in Rust. Convert works on CPU whereas sample needs CUDA.
|
|
|
|
Remember, `convert` should be used if you're planning on using the fine-tuned version of the stable diffusion.
