Point_cloud.ply file empty #20

Closed Assaciry closed 1 week ago

Assaciry commented 3 weeks ago

Hi, thank you for your work. I had a problem training on my custom dataset. I adjusted the block_dim, aabband max_block_idaccording to my dataset. I did the coarse training and data_partition. Seems like there is no problem. When i trained all the cells (16), there are point_cloud.ply files saved under point_cloud_blocks but they are empty and only containing header except cell number 10. I checked if there are any gaussian points detected, and there are. Points exist for all cells but they do not get saved to point_cloud.ply files except cell10. I dont know why. Can there be a problem with save function? Thank you in advance.

@Assaciry Hi, we have tested the latest pipeline, and no bug is found. Perhaps you can first try saving at iteration 1 by setting save_iterations to test if it works.
