You have disabled the safety checker for &lt;class &#x27;diffusers.pipelines.stable_diffusion.pipeline_stable_diffusion.StableDiffusionPipeline&#x27;&gt; by passing `safety_checker=None`. Ensure that you abide by the conditions of the Stable Diffusion license and do not expose unfiltered results in services or applications open to the public. Both the diffusers team and Hugging Face strongly recommend keeping the safety filter enabled in all public-facing circumstances, disabling it only for use cases that involve analyzing network behavior or auditing its results.
