奇点容器中的Jupyter Notebook

Question

当我进入奇点容器后，如何让jupyter笔记本在我的浏览器上运行--我找不到很多关于它的文档？我使用的是centos linux发行版，我必须通过ssh进入它。

容器中已经安装了Jupyter。在singularity shell --writable ....sif之后，如何让jupyter笔记本在浏览器上运行？basic：jupyter notebook --no-browser --port=7800返回这个错误：

启动notebook后，输出中会给出一个链接，您只需将该链接粘贴到浏览器中即可。请参见下面的示例输出。

您确定镜像已成功构建/完全传输吗？我无法复制这个错误。如果仍然出现该错误，请使用定义文件/如何生成镜像的命令更新问题。
