jupyter notebook/lab无法选择kernel (ipykernel 配置) / IProgress not found

注: 不安装widgets也可以使用notebook/lab运行代码.

租用服务器可能出现的问题

(base)conda install nbformat ipywidgets

Windows可能出现的问题

(base)conda install nodejs

需要手动清理C:\Users\Username\.jupyter\lab\workspaces中的缓存文件, 否则启动时报错.

安装jupyter notebook/lab

安装jupyter notebook/lab相当于安装前端, 只需要安装一次, 因此应该在base环境下安装.

(base)conda install jupyter notebook widgetsnbextension
(base)conda install jupyterlab widgetsnbextension
(base)pip install jupyterlab-language-pack-zh-CN

安装ipykernel

安装ipykernel相当于安装后端, 在每个需要用到jupyter notebook/lab的环境中都安装ipykernel.

(your_env_name)conda install ipykernel ipywidgets
(your_env_name)python -m ipykernel install --name your_env_name

注意conda安装之后还需要ipykernel安装, 直到出现以下提示信息.

Installed kernelspec your_env_name in C:\ProgramData\jupyter\kernels\your_env_name

查看ipykernel jupyter kernelspec list
