bug in training

[tangjw20]

优秀的工作！
但我在使用LLFF数据集进行训练时（使用您提供的Match Prior Extraction），出现了以下的bug：
File "/home/liushifa/tangjiawei/SCGaussian/scene/init.py", line 102, in save
self.gaussians.save_ply(os.path.join(point_cloud_path, "point_cloud.ply"))
File "/home/liushifa/tangjiawei/SCGaussian/scene/gaussian_model.py", line 609, in save_ply
storePly(os.path.join(os.path.dirname(path), "point_cloud_color.ply"), all_xyz, all_color * 255)
File "/home/liushifa/tangjiawei/SCGaussian/scene/dataset_readers.py", line 137, in storePly
elements[:] = list(map(tuple, attributes))
OverflowError: Python integer -221 out of bounds for uint8
您知道是什么原因吗？感谢您的回复
