to input patched latents, where `H` and `W` are the latent height and width respectively. A value of 128
means that the maximum supported height and width for image generation is `128 * vae_scale_factor *
patch_size => 128 * 8 * 2 => 2048`.
sample_size (`int`, defaults to `128`):
The base resolution of input latents. If height/width is not provided during generation, this value is used
to determine the resolution as `sample_size * vae_scale_factor => 128 * 8 => 1024`
