batchsize for 16384 output points

[ghost]

Hi, When I follow the instructions to train a TopNet model with 16384 output points, I found the batchsize can be only set to 1 for the high memory occupation to compute a chamfer distance, can you give me some suggestions? Besides, as mentioned in the paper, the ground truth points number keeps 2048 while the output points number is 16384, and it seems that somewhere should be moified in the code, because the emd can't be computed for the different number of ground truth points and output points?
