How to convert the .ply file of the PCN dataset into a .pcd file.Because when doing seh training, the input requirement of sest.py is a .pcd file, but after the PCN dataset is downloaded, it is a .ply file

Open your terminal, then "pcl_ply2pcd -h xxx.ply xxx.pcd" to convert ply to pcd using pcl lib.

There are multiple ply files with the same name, such as xxx_1.ply, xxx_2.ply, xxx_3.ply. If they are directly converted into pcd files, the SPM module still cannot read them.

But there are files with the same name inside such as xx_1.ply, xx_2.ply, xx_3.ply, etc. How should I deal with them?

I'm having the same problem as you. Have you solved this problem? Besides, I would like to know how the data is organized. If you can give me some information, I would appreciate it.

This is how I handled it. I copied multiple copies of the point cloud files in the complete folder and named them xxx_1.pcd, xxx_2.pcd.... Let them correspond to the files in the partial folder. Then modify the contents in the .list file。

But the problem I encountered when processing the house3k data set is that after processing the data set, the first dimension of many pillars is zero, which I cannot solve.
