This message usually appears when you have installed a new package or updated an existing one in your Python environment. In order for the changes to take effect, you may need to restart the Python kernel. You can do this by clicking on the "Kernel" menu in Jupyter Notebook and selecting "Restart". Alternatively, you can use the "Restart Kernel and Run All Cells" option to restart the kernel and run all the cells in your notebook from the beginning.
