memory leak #10

Closed againxx closed 6 years ago

Hi, I have been using this great 3d descriptor to do some works about 3d matching. But I found that the usage of GPU's memory was growing up increasely. Have you found this phenomenon?

Hello, does the memory leak occur during training? Or during the demo?

During the demo, I just used the demo net to compute descriptors of several hundreds of objects. It seems that the destructor of the Net class doesn't free all the resource of GPU. I finally fixed it up by using singleton pattern to make the Net class constructed only once.
