Question

我正在开发一个利用python的wbdata包的项目，它是世界银行api的包装器。它工作正常，直到我做出我猜想的大量数据请求，我不得不取消，现在当我使用import wbdata函数时，包甚至不会加载。这是我得到的

有人可以帮助我让这个包再次运作吗？

编辑 - 运行％debug cachefile.name后确定我得到以下内容;

   %debug cachefile.name

Answer 1

使用ipython的魔法%debug并检查cachefile的文件名是什么。如果它是常规文件，则名称应该可以cachefile.name访问。

然后核对那个文件。

Answer 2

我想我已经通过在Appdata \ Local \ wbdata中输入wbdata文件夹并删除其中的缓存文件来修复它。似乎现在有效。
