我学习了一门课程，并为 Jupyter Notebook 安装了 anaconda。 一切正常，但现在我为 tensorflow 2.0 创建了一个新环境。 我安装的旧笔记本电脑上的 tensorflow 2.0 环境运行良好，但现在我有一台新笔记本电脑，只有问题。当我打开 Jupiter notebook 并进入我的新环境时，我收到一条消息：
连接失败：与笔记本没有连接，笔记本尝试建立连接。
（Er kan geen verbinding met de notebookserver worden gemaakt。Het notebook blijft proberen opnieuw verbinding te maken。Controleer de configuratie van uw netwerkverbinding of notebookserver。）
我尝试了很多东西，删除环境并创建一个新环境，ipykernel，防病毒...... 有人可以帮帮我吗，我的底座好用吗？
