There was a discussion in #583 and/or Slack about sending the latents shape to the Flax scheduler, because
PNDM
requires it to properly initialize the state. We agreed to send the shape to all of them (until we maybe find a better solution), but I only ever added it to PNDM. Therefore, the stable diffusion pipeline was failing with other schedulers. For example, with the default weights that were uploaded to the repo for testing.
