  optional arguments:
    -h, --help            show this help message and exit
    --prompt [PROMPT]     the prompt to render
    --outdir [OUTDIR]     dir to write results to
    --skip_grid           do not save a grid, only individual samples. Helpful when evaluating lots of samples
    --skip_save           do not save individual samples. For speed measurements.
    --ddim_steps DDIM_STEPS
                          number of ddim sampling steps
    --plms                use plms sampling
    --laion400m           uses the LAION400M model
    --fixed_code          if enabled, uses the same starting code across samples
    --ddim_eta DDIM_ETA   ddim eta (eta=0.0 corresponds to deterministic sampling
    --n_iter N_ITER       sample this often
    --H H                 image height, in pixel space
    --W W                 image width, in pixel space
    --C C                 latent channels
    --f F                 downsampling factor
    --n_samples N_SAMPLES
                          how many samples to produce for each given prompt. A.k.a. batch size
    --n_rows N_ROWS       rows in the grid (default: n_samples)
    --scale SCALE         unconditional guidance scale: eps = eps(x, empty) + scale * (eps(x, cond) - eps(x, empty))
    --from-file FROM_FILE
                          if specified, load prompts from this file
    --config CONFIG       path to config which constructs model
    --ckpt CKPT           path to checkpoint of model
    --seed SEED           the seed (for reproducible sampling)
    --precision {full,autocast}
                          evaluate at this precision
