ModuleNotFoundError: No module named 'kaolin.nnsearch'

Hi, all,

After successfully building kaolin, I got the import error as follows:

    from kaolin.nnsearch import nnsearch
ModuleNotFoundError: No module named 'kaolin.nnsearch'

Any suggestion to fix this issue?

THX!

I have exactly the same problem. CentOS 7, with all the prereqs.

No, you just need to cd out of the .../kaolin/ directory

@monajalal your error is a different issue (it is ImportError). There should be some problems with your C++ version or library linking.
