LoRA

• You can specify the directory where the lora weights are stored via --lora-model-dir. If not specified, the default is the current working directory.

• LoRA is specified via prompt, just like stable-diffusion-webui.

Here's a simple example:

./bin/sd -m ../models/v1-5-pruned-emaonly.safetensors -p "a lovely cat<lora:marblesh:1>" --lora-model-dir ../models

../models/marblesh.safetensors or ../models/marblesh.ckpt will be applied to the model

Support matrix

ℹ️ CUDA get_rows support is defined here:
ggml-org/ggml/src/ggml-cuda/getrows.cu#L156
Currently only the basic types + Q4/Q5/Q8 are implemented. K-quants are not supported.

NOTE: The other backends may have different support.
