我正在开发一个项目，该项目利用 python 的 wbdata 包，它是世界银行 api 的包装器。它工作得很好，直到我提出了我猜想的大量数据请求，我不得不取消它，现在当我使用 import wbdata 函数时，甚至不会加载包。这就是我得到的

有人可以帮我让这个包再次工作吗？

谢谢

编辑-运行 %debug cachefile.name 后，我得到以下信息；

   %debug cachefile.name

使用 ipython 的魔法%debug并检查cachefile文件名是什么。如果它是一个常规文件，则 name 应该可以作为cachefile.name.

然后核对那个文件。

我想我已经通过进入 Appdata\Local\wbdata 中的 wbdata 文件夹并删除其中的缓存文件来修复它。似乎现在可以工作了。
