Jupyterlab离线安装及linux环境多Python内核设置

一、安装前准备

请浏览“安装多版本python 建立虚拟环境”，建立虚拟python环境。

假设原python路径为/usr/local/python3，虚拟环境将建立在/mpy/python39。

/usr/local/python3/bin/python3 -m venv /mypy/python39

 进入虚拟Python主环境

source /mypy/python39/bin/activate
python --version
pip list

二、下载升级安装包

请浏览“离线安装Python第三方库及依赖库”，离线下载升级安装包。

1.基本包

pip3 download pip setuptools -d /software/pip
pip3 install --no-index --find-links=/software/pip --upgrade pip setuptools

2.Jupyterlab包

pip3 download jupyterlab -d /software/jupyterlab
pip3 install --no-index --find-links=/software/jupyterlab jupyterlab

三、设置Jupyterlab

1.设定密码

jupyter lab password

2.配置参数

vim /root/.jupyter/jupyter_server_config.json

“password”行数据保持不变，添加其他行数据。 

{
  "ServerApp": {
    "password": "argon2:$argon2id$v=19$m=10240,t=10,p=8$rQAH6yOcwklwv8NwFCmA" ,
    "ip" : "*" ,
    "port" : 8080 ,
    "open_browser" : false ,
    "notebook_dir" : "/root" ,
    "allow_root": true
  }
}
 

四、安装中文插件

pip3 download  jupyterlab-language-pack-zh-CN -d /software/jupyter_extension
pip3 install --no-index --find-links=/software/jupyter_extension jupyterlab-language-pack-zh-CN

五、安装Jupyterlab服务

1.测试Jupyterlab

jupyter lab

2.创建jupyter.service文件

vim /etc/systemd/system/jupyter.service

[Unit]
Description=jupyterlab
After=network.service

[Service]
ExecStart=/mypy/python39/bin/jupyter lab 

[Install]
WantedBy=default.target

3.安装服务

systemctl start jupyter
systemctl enable jupyter

六、安装多内核环境

1.设定虚拟环境

#激活虚拟环境
/usr/local/python310/bin/python3 -m venv /mypy/python310
source /mypy/python310/bin/activate

#安装升级包
pip download pip setuptools -d /software/pip
pip install --no-index --find-links=/software/pip  --upgrade pip setuptools
#安装ipykernel
pip download ipykernel -d /software/ipykernel
pip install --no-index --find-links=/software/ipykernel ipykernel

 2.安装Jupyterlab的多内核环境

python -m ipykernel install --user --name python310 --display-name "Python-3.10.7"

 3.检查多内核设置

#进入主虚拟环境
source /mypy/python39/bin/activate

#查验版本信息
python --version
pip list
jupyter kernelspec list
