How to enable user specific kernels like PY2, PY3, R and Java for individual user in Jupyterhub

[Shaik Zainul]

Hi,

Currently i have setup jupyterlab and added programming language kernels like Python3, R and Java.

When i login jupyterhab from admin user i m able to view all this 3 kernels(Launchers Python3, R and Java)

However, if i login from user like User1, i able get all 3 kernels. now i want only specific kernel like R for user1.

How can i enable user specific kernels  like PY2, PY3, R for User1, User2 and User3  respectively on Jupyterhub

Please guide me to enable user specific kernels  like PY2, PY3, R for User1, User2 and User3  respectively on Jupyterhub

Regards,
