Support for Multi-Controlnet, and using separate images for controlnet about rerender_a_video HOT 7 OPEN

Yes, you need to create two controlnet models like model1 and model2 and load different saved pth.

And you will need to extract the controlnet features for each of the controlnet model. (you need to modify cond and the sample function

And to use two controlnet simultanously,
you need to add the multiple control features to the SD feature rather than a single control feature (you need to modify the code)

h += control.pop() to h += control1.pop() + control2.pop()

h = torch.cat([h, hs.pop() + control.pop()], dim=1) to h = torch.cat([h, hs.pop() + control1.pop() + control2.pop()], dim=1)

from rerender_a_video.

I notice that codes below:

    if cfg.control_type == 'HED':
          model.load_state_dict(
              load_state_dict('./models/control_sd15_hed.pth', location='cuda'))
      elif cfg.control_type == 'canny':
          model.load_state_dict(
              load_state_dict('./models/control_v11p_sd15_canny.pth',
                              location='cuda')) 

How should I change the code to load Both of them?

@williamyang1991 Thank you very much for the reply！ But I still need a bit more assistance...

I changed the cldm.py code as you listed above, and I changed the webUI code to be like this:

def update_detector(self, control_type, canny_low=100, canny_high=200):
    #if self.detector_type == control_type:
    #    return

    if control_type == 'canny':
        canny_detector = CannyDetector()
        low_threshold = canny_low
        high_threshold = canny_high

        def apply_canny(x):
            return canny_detector(x, low_threshold, high_threshold)

        self.detector1 = apply_canny

        midas = MidasDetector()

        def apply_midas(x):
            detected_map, _ = midas(x)
            return detected_map

        self.detector2 = apply_midas
       ......

       ddim_v_sampler = global_state.ddim_v_sampler
       model = ddim_v_sampler.model

       ### Changed Here
       detector1 = global_state.detector1 
       detector2 = global_state.detector2 

       controller = global_state.controller
       model.control_scales = [cfg.control_strength] * 13
       ......

        detected_map1 = detector1(img)
        detected_map1 = HWC3(detected_map1)

        control1 = torch.from_numpy(
            detected_map1.copy()).float().cuda() / 255.0
        control1 = torch.stack([control1 for _ in range(num_samples)], dim=0)
        control1 = einops.rearrange(control1, 'b h w c -> b c h w').clone()

        detected_map2 = detector2(img)
        detected_map2 = HWC3(detected_map2)

        control2 = torch.from_numpy(
            detected_map2.copy()).float().cuda() / 255.0
        control2 = torch.stack([control2 for _ in range(num_samples)], dim=0)
        control2 = einops.rearrange(control2, 'b h w c -> b c h w').clone()


        cond = {
            'c_concat': [control1, control2],
            'c_crossattn': [
                model.get_learned_conditioning(
                    [cfg.prompt + ', ' + cfg.a_prompt] * num_samples)
            ]
        }
        un_cond = {
            'c_concat': [control1, control2],
            'c_crossattn':
            [model.get_learned_conditioning([cfg.n_prompt] * num_samples)]
        }

But I ran into this error:

The RuntimeError suggests that the two conditions are not properly combined, I guess. Would you please take a look and give some suggestions? I'd really appreciate it~

Sorry about the lengthy post... I just realized that I did not change this:

        samples, _ = ddim_v_sampler.sample(

What should I change here?

from rerender_a_video.

You need change
control = self.control_model(x=x_noisy, hint=torch.cat(cond['c_concat'], 1), timesteps=t, context=cond_txt)

Since now you have two control_models and two features in cond['c_concat']

from rerender_a_video.

@williamyang1991 Thank you very much for the reply. I really appreciate it...

I found that code in cldm.py, but I don't know how to change it. Would you be so kind to show me? I browsed thru https://github.com/Mikubill/sd-webui-controlnet, but could not find how multi-controlnet is implemented there.

def apply_model(self, x_noisy, t, cond, *args, **kwargs):
    assert isinstance(cond, dict)
    diffusion_model = self.model.diffusion_model

    cond_txt = torch.cat(cond['c_crossattn'], 1)

    if cond['c_concat'] is None:
        eps = diffusion_model(x=x_noisy, timesteps=t, context=cond_txt, control=None, only_mid_control=self.only_mid_control)
    else:
        ### Here
        control = self.control_model(x=x_noisy, hint=torch.cat(cond['c_concat'], 1), timesteps=t, context=cond_txt)
        control = [c * scale for c, scale in zip(control, self.control_scales)]
        eps = diffusion_model(x=x_noisy, timesteps=t, context=cond_txt, control=control, only_mid_control=self.only_mid_control)

    return eps

from rerender_a_video.

I'm sorry that I'm under deadline pressure and cannot help you with every details.
And I'm not familar with https://github.com/Mikubill/sd-webui-controlnet.

The main idea is to track everywhere cond['c_concat'] is used and modify the corresponding code.
