Can not open ,ply file

[LIFT-Chen]

When I run this code on my computer, the generated ply file cannot be opened normally, cloudcompare and meshlab are not working, how can I solve this problem?

Error in CloudCompare:
[PLY]'Unexpected end of File'
[PLY]'Error reading 'x' of 'vertex' number '1919032'
An error occurred while loading 'resule_00_mesh': the thirdparty library in charge of saving/loading the file has failed to perform the operation.

Error in MeshLab:
Error : Unespected eof
