Question

我按以下方式组织了我的Python工作区：Scripts目录包含我自己编写的代码; Modules目录包含我需要在我的代码中导入和使用的第三方模块。这是代表：

/PythonWorkspace/
     /Scripts
         some_script.py
     /Modules
         __init__.py
         some_module.py
         some_module_DIR

脚本some_script.py需要使用some_class中的课程some_module.py，因此我按照here的说明进行操作，导入工作正常。

要创建some_module.py中包含的类的对象，我使用

some_object = some_class('path to some_module_DIR')

因为some_class需要访问some_module_DIR的内容。这会导致Pexpect引发的非常具体的错误（最后发布以便于阅读），该错误由some_module.py导入。

奇怪的是，如果我将some_script.py复制到/Modules并从那里运行它，那么在创建类some_class的对象时我不会收到任何错误。但是，在后一种情况下，我使用some_object = some_class()，因为在这种情况下使用默认路径。

问题：

可能是什么问题？
有任何建议的修复方法吗？

以下是我收到的错误：

注意：错误包含我的原始路径和对我正在使用的模块corenlp的引用（stanford解析器的python包装器）。
