jupyter notebook内核启动报错：ImportError: DLL load failed while importing _device

1.报错信息

File "D:\Programs\Programming\Anaconda3\envs\pytorch_mis\lib\site-packages\zmq\backend\cython_init _.py", line 6, in

from . import (

ImportError: DLL load failed while importing _device: 找不到指定的模块。

2.解决方案

pyzmq版本冲突，下载满足jupyter server版本的pyzmq

安装低版本的pyzmq

pip install pyzmq==23.0.0

提示jupyter-server 2.7.3需要pyzmp>=24，因此重新安装pyzmq，刚好满足条件即可

pip install pyzmq==24.0.0

安装后启动jupyter notebook，完美解决。
