emdloss compilation bug

[whuhxb]

Hi @yanx27 @ZhanHeshen

I use the environment you listed in PointCMT (cuda10.1, pytorch 1.4.0), and try to compile the emdloss, but the bugs occured as follow. How to solve?

Hi, may I ask which kind of GPU you used?

Hi, may I ask which kind of GPU you used?

Current, my GPU is Tesla V100 32G. Which kind of GPU should I use? Thanks.

It meets the needed environment of PointCMT, I am not sure why you come across this issue. Maybe it related to the code of emd, this package is hard to install during my experiments too. I suggest you can find other implementations of emd distance or chamfer distance, they can also work.
