conda环境下jupyter多环境支持 & 后台启动

首先查看下本地环境

(base) apple@yyq # conda env list
# conda environments:
#
base                     /Volumes/BanQ/opt/conda/anaconda3
airplane                 /Volumes/BanQ/opt/conda/anaconda3/envs/airplane
py_36                    /Volumes/BanQ/opt/conda/anaconda3/envs/py_36
py_37                 *  /Volumes/BanQ/opt/conda/anaconda3/envs/py_37
py_38                    /Volumes/BanQ/opt/conda/anaconda3/envs/py_38
tensor_37                /Volumes/BanQ/opt/conda/anaconda3/envs/tensor_37

安装ipykernel

输入以下命令退出当期虚拟环境，并安装ipykernel。

conda deactivate  ##退出当前虚拟环境

conda install ipykernel  ##安装ipykernel

进入已建虚拟环境中安装ipykernel

conda activate py_37 

python -m ipykernel install --name py_37 --display-name "python_37" 

#py_37是指已建环境名；python_37是指想要在jupyter notebook中显示的名字

打开Jupyter Notebook并选择所需虚拟环境

附

查看已有的kernel

jupyter kernelspec list

删除不想要的kernel:

jupyter kernelspec uninstall unwanted-kernel

在配置文件里配置别名 后台启动jupyter

alias note='nohup jupyter notebook >jupyter.log 2>&1 &'
