ModuleNotFoundError: No module named 'scipy.sparse.linalg.eigen.arpack'; 'scipy.sparse.linalg.eigen' is not a package

[MarkusKhoa]

Hi, I just run your code build_graph.py but it appears the issues ModuleNotFound although I've created Anaconda environment and installed Scipy package. Can you please tell me why this error exists?

Seems related to changes made by scipy 1.8

I try with from scipy.sparse.linalg import eigsh with scipy 1.8.1, and it works.
