Run Run. py to generate 6 different angle images with empty output images and pure black images. Guess it was a sampling error? There is no problem printing the input images. Could you please help me take a look, experts? Thank you

RuntimeWarning:invalid value encountered in cast images = (images * 255).round().astype("unint8")

运行run.py，生成6个不同角度的影像的outputimages为空，纯黑色图片。猜测应该是sampling出错？输入inputimages打印无问题。请各位专家帮忙看一下，谢谢
