Hi

I follow the following process to do the test. https://github.com/PaddlePaddle/models/tree/develop/PaddleCV/3d_vision/PointNet++

But I tried with the following paddle version, and get the same error.

• pip paddle gpu v1.8.1 with models tag v1.8.0
• conda paddle gpu v1.8.1 with models tag v1.8.0
• docker paddle gpu v1.8.1 with models tag v1.8.0
• docker paddle gpu v1.7.1 with models tag v1.7.0

I have set the LD_LIBRARY_PATH, and from the log, pointnet_lib.so is found. But failed due to link issue. Did I miss anything?
