change python version in jupyter notebook-CodePudding

I am using jupyter notebook and jupyter lab through jupyter hub. Currently, the python version recognized by jupyter is 3.6.8.

I want to set the python version to 3.7.3.

The python version installed on the server is as follows. (/usr/bin/python*)

The jupyter notebook kernel is set as follows in /usr/local/share/jupyter/kernels/python3/kernel.json

If you change the argv path to '/usr/bin/python3' or '/usr/bin/python3.7', the kernel is busy and the connection is not made. TT It works well only when argv path is '/usr/bin/python 3.6'.

Setting Code

sudo apt-get install python3-pip

sudo pip3 install ipykernel

sudo jupyter kernelspec install-self

CodePudding user response：

as this post says, you need to create a new kernel and this website shows how to do it
