4. 设置定制化kernal
   4.1 jupyter kernelspec list 查看系统中的kernal配置文件
   4.2 进入到相关目录修改相关kernel.json文件

{"argv": [
 # 设置环境变量
  "env",
  "VAR1=value1",
  "VAR2=value2",
  # 设置运行python环境
  "/path/to/python",
  "-m",
  "ipykernel_launcher",
  "-f",
  "{connection_file}"
],
# 在jupyter 中显示名称
"display_name": "Python (myenv)",
# 语言
"language": "python"
}

5. 创建新kernel

#1. 创建虚拟环境并激活
conda create --name my_new_kernel_env python=3.10
conda activate my_new_kernel_env

# 或者
python3 -m venv my_new_kernel_env
source my_new_kernel_env/bin/activate
#2. 安装依赖
pip install ipykernel

#3. 将环境添加到jupyter
python -m ipykernel install --user --name=my_new_kernel --display-name "Python (my_new_kernel)"

# 4. 验证
jupyter kernelspec list

6. 删除kernel
   jupyter kernelspec uninstall my_new_kernel
