我正在尝试使用Sphinx来记录我正在构建的Python包，并且一切正常，直到我添加了一些类。我只是提供全套警告，以免遗漏相关内容：

问题是，所有这些类方法（例如pynance.opt.core.Options.exps）都显示在输出文档中，而在类别页面的“方法”下，它们是可点击的链接。输出的唯一问题是“下一主题”链接在不应该的地方消失。
使用.rst的示例，我的pynance.opt.core.Options.exps文件的组织方式如下。首先，index.rst有：
.. toctree::
opt
...
然后我在同一目录opt.rst中有以下内容：
.. automodule:: pynance.opt
.. toctree::
opt.core
...
然后我在文件opt.core.rst：
.. automodule:: pynance.opt.core
.. autoclass:: Options
:members:
我在这里做错了什么？我希望我的课程方法全部正确显示，并且“下一主题”链接链接到我的整个包。
