stable diffusion dreaming
creates hypnotic moving videos by smoothly walking randomly through the sample space

example way to run this script:

$ python stablediffusionwalk.py --prompt "blueberry spaghetti" --name blueberry

to stitch together the images, e.g.:
$ ffmpeg -r 10 -f image2 -s 512x512 -i blueberry/frame%06d.jpg -vcodec libx264 -crf 10 -pix_fmt yuv420p blueberry.mp4

# "This is a notebook that uses DALL-E's decoder and CLIP to generate images from text. I will very likely make this better & easier to use in the future."
#
# rearranged to run locally on faster GPU
#
# directions:
# clone https://github.com/openai/DALL-E/ and https://github.com/openai/CLIP
# copy relevant files into one dir with this script
# install torch==1.7.1 and other stuff
