For single controlnet: `controlnet_conditioning_scale` must be type `float`.

i print the type and value of controlnet_conditioning_scale before self.check_inputs, it is float tyle and the value equals 1.0, while the code still return this error? Is it possible that there is an issue with the version of the diffusers library?

there are two methods this issue can be resolved.First,you can downgrade the diffusers version corresponding to diffusers==0.26.2 in the requirements.txt. Second,if you upgrade diffusers to updated version like 0.30.3, you should modify the code of

self.check_inputs(
            prompt,
            image,
            callback_steps,
            negative_prompt,
            prompt_embeds,
            negative_prompt_embeds,
            controlnet_conditioning_scale,
            control_guidance_start,
            control_guidance_end,
            callback_on_step_end_tensor_inputs,
        )

located in pipelines/OmsDiffusionControlNetPipeline.py as below

self.check_inputs(
            prompt,
            image,
            callback_steps,
            negative_prompt,
            prompt_embeds,
            negative_prompt_embeds,
            controlnet_conditioning_scale=controlnet_conditioning_scale,
            control_guidance_start=control_guidance_start,
            control_guidance_end=control_guidance_end,
            callback_on_step_end_tensor_inputs=callback_on_step_end_tensor_inputs,
        )

I run into the same issue and tried to update pipelines/OmsDiffusionControlNetPipeline.py as suggested, but still get this error:

!!! Exception during processing !!! For single controlnet: controlnet_conditioning_scale must be type float.

Ok I was also able to get rid of the error by updating VirtualTryOnPipeline.py to:

    self.check_inputs(
        prompt,
        control_image,
        mask_image,
        height,
        width,
        callback_steps,
        output_type,
        negative_prompt,
        prompt_embeds,
        negative_prompt_embeds,
        controlnet_conditioning_scale=controlnet_conditioning_scale,
        control_guidance_start=control_guidance_start,
        control_guidance_end=control_guidance_end,
        callback_on_step_end_tensor_inputs=callback_on_step_end_tensor_inputs,
        padding_mask_crop=padding_mask_crop,
    )
