pointnet2_cuda问题

[liyx2001]

pytorch=1.9.1 +CUDA11.1 无法运行，如何适配？
编译pointnet2_cuda时报错。

Sorry for the late reply.

It is due to the misalignment between the CUDA you use to compile the lib and the CUDA you use to run.

You may need to change the environment variable $CUDA_HOME to point to a system CUDA with version 11.x, and recompile the pointnet2. Or change the pytorch version.
