question about training process

[wra1229]

Hi, excellent work!
I try to re-train your net with 3dmatch datasets, during the process I found that the parameter 'src_mask' is all True, I think the True or False in 'src_mask' means the point in the source point cloud has the possibility of correspondence to other points in the target point cloud.
Am I wrong? or this parameter will change in 4dmatch training process?
Hope for your reply!
