这曾经是可能的（请参阅这篇文章：How get BQL (bLOOMBERG) query from python）但是我现在无法让它工作。复制大量包/文件后，我陷入了以下 AttributeError：“zmq.eventloop' 没有属性 'ioloop'”，如果我读到，这是因为我试图在沙盒终端版本之外进行访问。有人找到了在 python 本地使用 BQL 的方法吗？谢谢 - 下面完整的回溯：

猜测可能与 Spyder 从 zmq 16.0.0 升级有关？ 看起来像： 模块：zmq.eventloop.ioloop 该模块在 pyzmq 17 中已弃用。使用tornado.ioloop。 https://pyzmq.readthedocs.io/en/v26.2.0/api/zmq.eventloop.ioloop.html
