@sshaoshuai 您好，非常感谢您提供的代码，我使用的时候出了一些问题，想向您请教一下。我成功地执行了 python setup.py install 代码，CUDA的OP也可以成功调用，但是训练过了几个epochs就会出现一个问题：CUDA: an illegal memory access was encountered. （每次训练的报错行数不一样，但是最后的报错一样）经过排查我觉得可能与CUDA和里面的线程分配有关，而且这个代码我之前几个月用着都没问题，这个问题是最近出现的。请问您是否遇到过类似的情况？下面的是一次报错的具体信息。非常感谢。 `e=/pytorch/aten/src/THC/THCCachingHostAllocator.cpp line=265 error=77 : an illegal memory access was encountered THCudaCheck FAIL file=/pytorch/aten/src/THC/THCCachingHostAllocator.cpp line=265 error=77 : an...

Hi @sshaoshuai, Shouldn't evaluation be performed in `eval()` mode? https://github.com/sshaoshuai/Pointnet2.PyTorch/blob/master/tools/train_and_eval.py#L103
