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

原因分析：

scipy更新之后不兼容

from scipy.sparse.linalg.eigen.arpack import eigsh

改为

from scipy.sparse.linalg import eigsh

解决方案：

# 过时了
from scipy.sparse.linalg.eigen.arpack import eigsh
# 改为
from scipy.sparse.linalg import eigsh
