No module named tools

Hi

To do the anharmonic energy part of hiphive code, I need to use the command from tools import compute_energy_surface but this module is not known and I can not import it!! could you please guide me to solve it?

Thanks

You need to stand in the correct directory when running the example. hiphive/examples/advanced_topics/anharmonic_energy_surface/tools.py
So you need to know where you installed hiphive
