Ray installation error

I have a sagemaker notebook instance created in my AWS account. In the Jupyter lab, I installed ray successfully from terminal. Commands used:

pip install -U “ray[default]”.

sh-4.2$ ray --version
ray, version 2.10.0

Then I open my Jupter python notebook and tried to import ray. Encountering no module found. Could you pls help point what am I missing ?

Did you have the notebook open before installing Ray? Try re-initializing the kernel.

Yes, I have tried re-initializing the kernel. Didn’t help.
