我正在尝试启动我的 AI 项目，需要构建一个 jupyter 笔记本。 我的步骤如下。
- 下载 Windows 版 anaconda（我以前没有使用过 python） - 安装anaconda（因此将其注册为python 3.11） - 从 pytorch.org 获取命令提示符并运行 - 打开 anaconda 提示符（尝试了用户和管理员）并输入“jupyter notebook”或“jupyter notebook --notebook-dir=D:\WorkPlace2\PyTorch” （文件夹打开没有错误） - 我触发 new 并创建一个 *.ipynb 文件。 然后出现“正在连接服务器”，很快就变成“未连接”
我在cmd中收到以下错误消息。
(base) C:\WINDOWS\system32>jupyter notebook --notebook-dir=D:\WorkPlace2\PyTorch

Read the migration plan to Notebook 7 to learn about the new features and the actions to take if you are using extensions.
https://jupyter-notebook.readthedocs.io/en/latest/migrate_to_notebook7.html
Please note that updating to Notebook 7 might break some of your extensions.

我尝试卸载 anaconda 并重新启动系统并重新安装 anaconda。 但我无法解决这个问题。 在我重装系统之前，我尝试过这个，没有问题。 但现在，我找不到原因。
我认为这是因为系统环境路径的原因。
如果您之前安装过其他与Python相关的程序，例如PyCharm，可能就是这个原因。
检查此处为什么（或为什么不）将 anaconda 添加到路径。
如果您已经安装了 Pycharm，请尝试卸载 PyCharm 并重新安装 anaconda。
如果这不能解决您的问题，您甚至可以尝试重新安装 Windows 系统。
