missing modules: variogram_model and gamv_yuhao

Hi Hao,
I tried the structural analysis notebook and it complained about two missing modules.
Any idea what's happening?

>>> import variogram_model as vm
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'variogram_model'
>>> from gamv_yuhao import Gamv
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'gamv_yuhao'
