I observed the source code for the training and testing data set is a.h5 file, I observed the internal composition, I also created a copy of the.h5 file, but the following error occurs at runtime:

Source training and test data set.h5 file composition:

I copied the.h5 file in the source code to generate my own test data set file as follows:

I think 2464 is the number of training/test data sets, 5000 is the number of points after downsampling, 3 is three-dimensional coordinate data, and the bottom transform is the coarse registration coordinate transformation matrix. So I also copied a.h5 file according to this composition, but there was an error at runtime. How to solve this problem?
