Error when editing scene

[WoodwindHu]

Hi, I try to remove a car from the scene, but it turned out this error:
'''
RuntimeError: Error(s) in loading state_dict for PointTexture:
size mismatch for texture_: copying a param with shape torch.Size([1, 8, 2547322]) from checkpoint, the shape in current model is torch.Size([1, 8, 2543402]).
'''
It seems like the model shape should be same to the point cloud size.
How can I edit the point cloud correctly?
