3. 确认是否关闭当前notebook,选择"Yes"
4. kernel会重新启动,重新加载所有的包和库,以确保更新生效
注意:重新启动kernel会清空当前的内存,你需要重新运行之前的代码。

you may need to restart the kernel to use updated packages.
This message usually appears in Jupyter notebooks when new packages or updates have been installed and the kernel needs to be restarted in order to use them.
To restart the kernel, you can go to the "Kernel" menu on the notebook toolbar and select "Restart Kernel". Alternatively, you can use the keyboard shortcut "0, 0" (press the 0 key twice).
After restarting the kernel, you should be able to use any newly installed or updated packages. Note that restarting the kernel will also clear the memory of any variables or data that were previously stored, so you may need to rerun any necessary code cells.

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:
```shell
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:
```shell
pip list
```
