detailed usage:

import torch
import kiui
from mvdream.pipeline_mvdream import MVDreamPipeline

pipe = MVDreamPipeline.from_pretrained('./weights', torch_dtype=torch.float16)
pipe = pipe.to("cuda")

prompt = "a photo of an astronaut riding a horse on mars"
image = pipe(prompt) # np.ndarray [4, 256, 256, 3]

kiui.vis.plot_image(image)
