Python版本是2.7.
Python version is 2.7.
是否有任何有关如何解决此问题的指针?
Any pointers to how I can resolve this?
推荐答案
我修改了文件"/Library/Python/2.7/site-packages/notebook-5.2.2-py2.7.egg/notebook/base /zmqhandlers.py"以删除io_loop
参数.
I modified the file "/Library/Python/2.7/site-packages/notebook-5.2.2-py2.7.egg/notebook/base/zmqhandlers.py" to remove the io_loop
argument.
根据bkanuka的评论,这是直到Jupyter发布新版本之前的方法.
Based on bkanuka's comment, this is the way to go until Jupyter releases a new version.
