在python中访问已翻译本体时发生堆栈溢出

我有一段非常简单的代码，但它已经出错了。我的代码 应该在本体中迭代类名并打印出来。这适用于前20或20个月 因此，但随后会出现以下错误：

Fatal Python error: Cannot recover from stack overflow.

我使用owlready2的代码只有以下4行：

from owlready2 import get_ontology 
onto = get_ontology("Ontologie.owl").load() 
for this in onto.classes(): 
    print(this)

你能给我指出错误吗？我最初在MacBook上试用过它，但现在我也在运行Arch的计算机上进行了测试，同样的错误。

问题可能出在您的本体中。本体中可能定义了一个循环。A是B的子类，B是A的子类。您可能需要共享本体，以便我们能够指出问题。遗憾的是，我无法共享本体。但无论如何，谢谢你回答这个问题！我会看看里面是否有循环。这一行（

文件）/Users/PATH/.env/lib/python3.7/site packages/owlready2/namespace.py），“\u get\u by\u storid

”中的第538行）是一个递归错误（），因此在您的本体中有一些东西是自圆其说的。循环在OWL中并不少见，也不被禁止。。。因此，在我看来，在这种情况下，它将是

owlready2

中的一个bug。或者一个限制，但它应该被记录在某个地方。不确定是否是一个bug，但至少OWL中的cycles不应该破坏API-如果它不能处理cycles，我认为一个更有意义的异常会更好。我的意思是，如果一个最小本体仍然失败，你可以尝试使用一个循环。否则，因为我们不知道你们的本体论，我们无法判断。显然，您可以将本体加载到Protege中，看看它是否有效，也许还可以应用推理程序。
