I have meet the same problem. Have you solved it?

I solved the problem by changing dll=np.ctypeslib.load_library('render_balls_so','.') into dll = np.ctypeslib.load_library('render_balls_so.so', '.')

I solved the problem by changing dll=np.ctypeslib.load_library('render_balls_so','.') into dll = np.ctypeslib.load_library('render_balls_so.so', '.')

same problem here and the above workaround doesn't seem to work for me. maybe the issue is that I'm trying to run the code on google colab, but I can't be sure.

Thanks a lot!!!

我通过dll=np.ctypeslib.load_library('render_balls_so','.')改成解决了这个问题dll = np.ctypeslib.load_library('render_balls_so.so', '.')

我用此方法试过了，可是我这里行不通

I've tried this on windows and it's been impossible. But I tried this solution on linux and it worked immediately.

try to use absolute path like "home/xxx/pointnet.pytorch/utils/" instead of '.'
