用VS运行jupyter时报错如下
代码语言：javascript复制Jupyter kernel cannot be started from 'Python 3.6.9 64-bit ('py36': conda)'. Using closest match Python 3.7.4 64-bit instead.
Error starting original kernel: python -m jupyter notebook --version is not running是因为python -m jupyter notebook --version这个指令无法运行，故在命令行中尝试（已经激活了自己想要打开jupyter的那个虚拟环境，在我这里是py36），结果：
(py36) D:>python -m jupyter notebook --version
Traceback (most recent call last):

from zmq.eventloop import ioloop
ModuleNotFoundError: No module named 'zmq.eventloop'发现问题在zmq上，jupyter notebook依赖它，所以就会出现问题
根据 https://github.com/jupyter/notebook/issues/3435
这一问题的原因可能是pyzmq的安装中有冲突，解决方法为：
代码语言：javascript复制pip uninstall pyzmq
pip install pyzmq让pip在重装时自己解决冲突。
再次在VS Code中重启jupyter notebook，可以成功运行。
