you may need to restart the kernel to use updated packages.

This message usually appears when you have installed or updated a package in your Python environment, and the changes have not been recognized by the kernel. To resolve this issue, you can try restarting the kernel by clicking on the "Restart kernel" button in the Jupyter notebook interface. Alternatively, you can restart the kernel using the command `Kernel -> Restart` in the menu bar, or by running the command `!pip install --upgrade <package-name>` in a code cell to upgrade the package and then restarting the kernel.
