Question

我遇到了这个奇怪的问题，我无法从Python中的数学模块导入。但是导入整个模块有效。

ImportError                               Traceback (most recent call last)

     19 from core.plot import ImageData, IndexSelector

/Users/bdhammel/Documents/research_programming/core_diag/core/math.py in <module>()
      3 import sys
      4 import math
----> 5 from math import factorial
      6 from scipy.integrate import cumtrapz
      7

ImportError: cannot import name factorial

我的目录结构是这样的

Main file
    from math import factorial # works fine here
    import custom_module

custom_module
    import math # works fine
    from math import factorial # breaks

我不知道为什么会这样。任何帮助，将不胜感激。

我在虚拟环境中工作。

如果您要导入math内的core.math，请启用绝对导入，这样您就不会获得core.math：

from __future__ import absolute_import

无法从Python中的'math'导入模块
