Describe the actual behavior

Describe the expected behaviour

To an image to be generated

Standalone code/steps you may have used to try to get what you need

Code: mediapipe-samples/examples/image_generation Models tried: runwayml/stable-diffusion-v1-5 and hakurei/waifu-diffusion-v1-4 both converted on Google Colab by following the tutorial. I am unsure if it is relevant, but the conversion script gave the following warning: /content/convert.py:42: RuntimeWarning: overflow encountered in cast v.numpy().astype("float16").tofile(output_bin_file)

I have initially created the issue in the samples repo but from what I have gathered by debugging the demo app, the issue could be caused by Mediapipe Image Generator itself which returns full black image no matter what.

Thank you.
