Thanks for your great work, I tried to extract the results generated by octree-gs using gaustudio and got the following error:

Loading trained model at iteration 40000

features_dc = self._f_dc.reshape(len(self._f_dc), -1, 3)
RuntimeError: cannot reshape tensor of 0 elements into shape [0, -1, 3] because the unspecified dimension size -1 can be any value and is ambiguous
What is the problem and how should I fix the issue? Is it that gaustudio is not able to perform facet extraction on octree-gs generated results? Looking forward to your reply, thank you very much!
