Code for L2 Chamfer distance

[ShenZheng2000]

Hello, authors! I would like to know how you obtained the L2 Chamfer distance in Table 2 of your paper.
After executing your code on the c3d dataset, I obtained the following outcome, which seems to be the L1 Chamfer distance.

============================ TEST RESULTS ============================

From my understanding, the pytorch CD is actually both L2-norm, but one is L2-squared-root. However in the convention of point cloud papers, some authors refer to L1-norm as 'without sqrt()'.
