Dear creator, thank you for your efforts and sharing!
I noticed that in the code related to obtaining data in the testing section, the 3dmatch dataset needs to be in PCD format. After converting PLY to PCD for testing, the same error still occurred. The error code is as follows. How can I solve this problem
C:\ProgramData\Miniconda3\python.exe C:\PointNetLK_Revisited-main\test.py
