Windows10下Jupyter创建新笔记本遇Bad file descriptor错误求助

Jupyter Notebook内核忙碌并弹出"Bad file descriptor"错误的解决办法

问题场景

在Windows10 64位系统中,通过CMD启动本地Jupyter Notebook,获取访问URL后尝试创建新笔记本时,内核长时间处于忙碌状态且无法停止,随后CMD中弹出Bad file descriptor错误,具体运行日志如下:

C:\Users\Стася>jupyter notebook

    Or copy and paste one of these URLs:

可行解决办法

  • 重置Jupyter配置文件

    1. 关闭所有Jupyter相关进程(包括CMD窗口和浏览器中的Jupyter页面)
    2. 打开CMD,执行命令:jupyter notebook --generate-config
    3. 找到生成的配置文件(默认路径为C:\Users\你的用户名\.jupyter\jupyter_notebook_config.py),打开后定位到c.NotebookApp.use_redirect_file一行,修改为c.NotebookApp.use_redirect_file = False,保存文件
    4. 重新启动Jupyter Notebook
  • 降级zeromq库
    错误日志指向zeromq的epoll模块,Windows不支持epoll,大概率是版本兼容性问题:

    1. 打开Anaconda Prompt(或CMD,确保激活了对应的conda环境)
    2. 执行命令:pip install pyzmq==22.3.0
    3. 重启Jupyter Notebook
  • 更换Jupyter启动目录
    当前启动目录包含非英文字符(C:\Users\Стася),特殊字符可能引发文件描述符异常:

    1. 在本地创建纯英文路径的文件夹,例如D:\Jupyter_Workspace
    2. 打开CMD,通过cd D:\Jupyter_Workspace切换到该目录
    3. 执行jupyter notebook启动服务,再尝试创建新笔记本
  • 清理Jupyter运行时文件

    1. 关闭所有Jupyter进程
    2. 找到Jupyter运行时目录(默认路径为C:\Users\你的用户名\AppData\Roaming\jupyter\runtime)
    3. 删除该目录下的所有文件
    4. 重新启动Jupyter Notebook
