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

As an AI language model, I do not have the capability to restart kernels or install packages on your local machine. However, you can restart the kernel in your Jupyter Notebook by clicking on the "Kernel" menu and selecting "Restart Kernel". This will clear all the variables and code that have been run in the notebook so far.

If you need to install packages, you can use the package manager "pip" in your command prompt or terminal. For example, if you want to install the package "numpy", you can type "pip install numpy" in your command prompt or terminal.

这个提示通常出现在Jupyter Notebook中，意味着你需要重新启动内核才能使用更新后的包。你可以通过点击菜单栏中的Kernel -> Restart来重新启动内核。如果问题仍然存在，你可能需要升级相关的库，可以使用以下命令升级库：

pip install --upgrade 库名

其中，将“库名”替换为需要升级的库的名称。如果你不确定需要升级哪些库，可以使用以下命令查看所有已安装的库及其版本：
