consulting for the implement details of sparse convolution

[benzhangwang]

Hello,
I has completed the training and testing for depth completion with your sparse convolution code, but the result show that the error of D1-all increase rapidly when we decrease the density of input depth. I want to known your experimental result and if you can offer more guidance, please contact we with email. My email is wangbenzhang12@nudt.edu.cn.
