LyliaEngine/Pony_Diffusion_V6_XL · Can't not load the model

If I use

from diffusers import DiffusionPipeline

pipe = DiffusionPipeline.from_pretrained("Bakanayatsu/Pony-Diffusion-V6-XL-for-Anime")
pipe.load_lora_weights("LyliaEngine/Pony_Diffusion_V6_XL")

then I will get

ValueError: Provided path contains more than one weights file in the .safetensors format. Either specify `weight_name` in `load_lora_weights` or make sure there's only one  `.safetensors` or `.bin` file in  LyliaEngine/Pony_Diffusion_V6_XL.

So I use

pipe.load_lora_weights("LyliaEngine/Pony_Diffusion_V6_XL",
                       weight_name = "ponyDiffusionV6XL_v6StartWithThisOne.safetensors",
                       )

but I get

ValueError: Invalid LoRA checkpoint.
