创建类的对象时出现Python PExpect错误

Question

我按照以下方式组织Python工作区：Scripts目录包含我自己编写的代码；Modules目录包含我需要导入并在代码中使用的第三方模块。以下是陈述：

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

脚本some_script.py需要使用来自some_module.py的类some_class，所以我按照找到here的说明进行操作，导入工作正常。在

要创建some_module.py中包含的类的对象，我使用

^{pr2}$

由于cd4{cd8}的内容需要访问。这会导致^{}引发的一个非常具体的错误（为了可读性，在结尾处发布），该错误由some_module.py导入。在

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some_class类的对象时不会出错。但是，在后一种情况下，我使用some_object = some_class()，因为本例中使用了默认路径。在

问题：

• 有什么问题吗？在
• 有什么建议吗？在

这是我得到的错误：

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（斯坦福解析器的python包装器）。在
