解决jupyter notebook操作中终端出现Bad file descriptor (C:\ci\zeromq_1616055400030\work\src\epoll.cpp:100)问题
在学习jupyter notebook时,我在Jupyter Notebook的界面新建了一个文档,如下所示
当我点进去对文档就行重命名操作,出现error信息,我发现在终端里出现如下报错,并且中断了jupyter notebook.
搜索了很多回答,说是因为建立windos用户名使用了中文,而很多pyhon以及pyhon相关的库对中文路径是很不友好的(好巧不巧鄙人用户名就是"德玛西亚",心中一万匹草泥马奔过),大概的解决方案如下
1:修改windows用户名(感觉此方法一劳永逸,避免出现因为此类原因造成的问题)
感谢大佬提供的解决方案:
修改windows用户名
但是此类方法,环境变量中使用了中文也需要进行更改.我比较怕麻烦,有没有不更改用户名的办法呢
2:降级pyzmq版本
使用pip list查了下我的pyzmq版本为23.2.0,网上所说使用的都是19.0.2,此次我下载的为22.1.0版本,重命名也是可以的
先卸载你安装的pyzmq
(datasci) D:\>pip uninstall pyzmq
Found existing installation: pyzmq 23.2.0

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
jupyter-client 7.3.5 requires pyzmq>=23.0, but you have pyzmq 22.1.0 which is incompatible.
Successfully installed pyzmq-22.1.0安装成功,但是出现以上ERROR信息,意思为:
pip 的依赖项解析器当前未考虑安装的所有包。此行为是以下依赖项冲突的根源
jupter-client 7.3.5需要pyzmq版本大于23.0,但是你的pyzmq版本19.0.2是不支持的
继续解决方案:降低jupyter-client的版本，先卸载，后重新安装jupyter-client==7.2.0。
