In standalone,I had a error"No module named 'cpp_wrappers.cpp_subsampling.cpp_subsampling'"when I tried to train S3DIS datasets.Why it happaned,and how to handle it?

You have to run the build.bat files, both in cpp_neighbors and cpp_subsampling

Yes，I changed the versions of python and numpy, these two .bat files could run. Now, I had a miatake"NotADirectoryError: [Errno 20] Not a directory: '../data/s3dis/Stanford3dDataset_v1.2_Aligned_Version/Area_1/.DS_Store/coord.npy'", is it a problem about data directory? Thanks for your reply!
