我已经构建了一个包含最新 anaconda 版本的奇点映像（jupyter.sif），我想用它来运行一个 jupyter 笔记本。

我想运行这样的东西：

singularity exec \
  --bind /path/outside/image/:/path/inside/image/ \
  jupyter.sif jupyter notebook \
    --notebook-dir=/path/to/dir --no-browser --ip=127.0.0.1

本质上，只需启动一个普通的 jupyter notebook，它将使用 python 版本和安装在奇异图像中的包。理想情况下，笔记本将在图像之外读取和写入文件（因此我指定了绑定路径）。

但是，当我运行上述命令时，出现以下错误：

我认为这是因为笔记本正在尝试在图像中写入内容，并且因为我没有将图像作为 sudo 运行（我不想这样做），而且我在执行图像时也没有指定 --writable （也不想这样做），它抱怨无法在图像中写入。

有没有办法“告诉”图像在我的主目录而不是图像内部读取和写入文件？

谢谢

我刚刚遇到了同样的问题，这似乎已经为我解决了：将 /run/user 内部映射到容器到外部的工作目录（或您选择的目录）。对于您的情况，可能意味着：

singularity exec --bind /path/outside/image/:/path/inside/image/ --bind $PWD:/run/user jupyter.sif jupyter notebook --notebook-dir=/path/to/dir --no-browser --ip=127.0.0.1

像这样运行时，在我的情况下1000创建了一个文件夹

这适用于奇点实例，例如：

   singularity instance.start --writable --contain --bind shared:/shared sandbox/ jupyter

接受的答案有效，但这是另一个不需要绑定安装的解决方案。可以unset XDG_RUNTIME_DIR在运行 jupyter notebook 之前运行，这个错误就会消失。
