【问题描述】：

大家好，这是我在运行 python 文件时遇到的问题

execfile("create_revdict.py")

我明白了

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "create_revdict.py", line 91, in <module>
    combos =  QuickSky.get_combos(det_keys)
AttributeError: 'module' object has no attribute 'get_combos'

但是当我查看 QuickSky 模块时，它是从 pyc 文件导入的我找到了

看来 QuickSky 有一个属性 get_combos。

很遗憾，我没有编写 QuickSky.pyc，因此我无法访问 QuickSky.py 源代码。

可能是什么错误？

【解决方案1】：

正如消息告诉您的，get_combos 不是模块QuickSky 的函数。您可以通过dir(QuickSky)查看该模块的内容。

看起来get_combos 是QuickSky.Mapper 类的方法。您可能需要使用适当的 dets 参数创建后者的实例。
