我正在尝试使用git.bash从github运行一些测试-https://github.com/freude/NanoNet-但是当我运行鼻子测试时，我遇到了 ERROR：Failure：ModuleNotFoundError（没有名为“ atoms”的模块） ）。
我正在运行python 3.7.0，win8（64位）。我不太确定如何解决这个问题。任何帮助将不胜感激。

答案 0 :(得分：0)
有问题的代码是为Python 2编写的；例如，文件tb/__init__.py包含以下行：
from atoms import Atom
from hamiltonian import Hamiltonian
from hamiltonian_sparse import HamiltonianSp
from aux_functions import get_k_coords, yaml_parser
from hamiltonian_initializer import set_tb_params, initializer
from greens_function import surface_greens_function
所有提到的模块都存在于tb/文件夹中，因此导入它们的正确方法是在其名称前面加上一个点（例如from .atoms import Atom）；此处看到的旧的absolute_imports之前的旧导入方式仅适用于Python 2。
您的可以尝试重写代码以修复所有导入，但是几乎肯定会存在其他跨版本不兼容的情况。使代码运行的唯一肯定的方法是在Python 2而不是Python 3下运行它。
