Getting "undefined symbol" error when importing nv_wavenet_ext #92

I'm getting "undefined symbol" error when importing nv_wavenet_ext as follows:

In [1]: import torch

In [2]: torch.__version__
Out[2]: '1.1.0'

In [3]: import nv_wavenet_ext
---------------------------------------------------------------------------

Did you solve it? I have the same problem

I solved it by cleaning up the repo, re-clone it and rebuild it. Also remember to always import torch before import nv_wavenet_ext
