the safetensors weights are downloaded if they’re available and if the
safetensors library is installed. If set to True, the model is forcibly loaded from safetensors
weights. If set to False, safetensors weights are not loaded.    Instantiate a DiffusionPipeline from pretrained pipeline weights saved in the .ckpt or .safetensors
format. The pipeline is set in evaluation mode (model.eval()) by default.  Examples:   Copied >>> from diffusers imp
