Ipython Kernel not available in jupyter

I am following the Riva tutorial on github and it states:
5. Create an IPython kernel - The Riva tutorials Jupyter notebooks will be using this kernel in the next step.
ipython kernel install --user --name=venv-riva-tutorials

  1. Start the Jupyter notebooks server. jupyter notebook --allow-root --port 8888
    If you have a browser installed on your machine, the notebook should automatically open. If you do not have a browser, copy/paste the URL from the command.
    Once you open a Riva tutorial notebook on a browser, choose the venv-riva-tutorials kernel by KernelChange kernelvenv-riva-tutorials

I have created the kernel mentioned in step 5 but the kernel is not available in jupyter as mentioned in step 6… Any ideas?

Hardware - GPU Jetson Xavier NX
Hardware - CPU
Operating System Ubuntu 20.04
Riva Version 2.2
TLT Version (if relevant)
How to reproduce the issue ? (This is for errors. Please share the command and the detailed log here)

Solved it on my own. I removed the kernel and reinstalled it.
