No module named 'lpsmap.ad3ext.parse'

Dear Vlad,

Thanks for your amazing work.

I am trying to install lpsmap and having trouble with an error when I use it.

from lpsmap.ad3ext.parse import Parse
ModuleNotFoundError: No module named 'lpsmap.ad3ext.parse'

I first download the eigen as indicated in https://gitlab.com/libeigen/eigen and then perform the following scripts
export EIGEN_DIR=/path/to/eigen
python setup.py build_clib # builds ad3 in-place
pip install . # builds lpsmap and installs

My env is:
Unbuntu16.04
Python: 3.6
Pytorch: 1.6.0

I am not sure if the eigen should be compiled firstly.

Would you please give some suggestions?

Thanks a lot!
