Question

我有一些要在其上安装jupyter Notebook的AWS服务器。

我执行以下步骤：

转到我的主目录并使用创建虚拟环境

python3.6 -m venv env

激活静脉

source env/bin/activate

安装Jupyter

python -m pip install --upgrade pip

python -m pip install jupyter

运行jupyter笔记本

jupyter notebook

在我运行jupyter notebook之前，一切似乎都可以正常工作。

我收到以下错误：

(env) root@ip-172-51-23-114:/home/USER# jupyter notebook --allow-root
[I 21:14:53.193 NotebookApp] Serving notebooks from local directory: /home/USER

        file:///root/.local/share/jupyter/runtime/nbserver-25435-open.html
    Or copy and paste one of these URLs:

我通过RStudio的终端安装python和jupter笔记本。

我应该尝试在实例上安装chrome还是其他网络浏览器？

Answer 1

根据您配置的网络权限，您可以尝试使用域（后跟端口）连接到EC2实例上的Jupyter笔记本。例如，

https://<ec2-address>:<port>

对于us-west-2区域中的示例实例：

https://ec2-52-39-239-66.us-west-2.compute.amazonaws.com:8888/

它可能会提示您在EC2身份验证窗口中输入令牌，也可以将其附加到上述URL的末尾：

https://ec2-52-39-239-66.us-west-2.compute.amazonaws.com:8888/?token=4a83abb3edf214bff5796dae4cf0ed756b1d99972e4134e7

在Amazon AWS上安装jupyter笔记本
