ccess to important properties such as num_timesteps and guidance_scale. You can modify these properties by updating the underlying attributes. For this example, you’ll disable CFG by setting pipeline._guidance_scale=0.0. step_index and timestep tell you where you are in the denoising loop. Use step_index to turn off CFG after reaching 40% of num_timesteps. callback_kwargs is a dict that contains tensor variables you can modify during the denois
