+## Converting weights

 The format of state dicts used by Refiners is custom and we do not redistribute model weights, but we provide conversion tools and working scripts for popular models. For instance, let us convert the autoencoder from Stable Diffusion 1.5:
 
 ```bash
 python "scripts/conversion/convert_diffusers_autoencoder_kl.py" --to "lda.safetensors"
 ```
 
-If you need to convert weights for all models, check out `script/prepare_test_weights.py` (warning: it requires a GPU with significant VRAM and a lot of disk space).
