No module named 'pointnet2_cuda'

在运行readme Trained model中最后一行的代码“bash run_eval_model.sh”的时候发生了以下错误：
(myconda) root@6a05092648e6:/mnt/EPNet-master/tools# bash run_eval_model.sh
Traceback (most recent call last):

import pointnet2_cuda as pointnet2
ModuleNotFoundError: No module named 'pointnet2_cuda'

我猜测这是因为EPNet-master/pointnet2_lib/pointnet2文件夹下缺少了pointnet2_cuda.py文件的缘故。通过同文件夹下的setup.py似乎可以生成对应的文件，但是具体如何使用这个setup.py文件我还不是很清楚，请问谁可以帮忙看看吗？

may be the gcc version dismatching, or nvcc version is different from torch.cuda version
