Jupyter OSError：[Errno 122] 超出磁盘配额：

我在服务器上运行 jupyter notebook 并使用 ssh 隧道访问它。尝试启动 jupyter 时出现内核错误。

错误信息似乎很明显，但我不知道如何解决它。我尝试从我的帐户中删除一些大文件并重新启动 jupyter，但仍然出现同样的错误。此外，在尝试一些需要大量内存的计算后也会发生这种情况。计算生成的文件（尚未完成）只有 2.8G，但我怀疑某些地方有一些缓存文件。

配置：Linux 版本 3.10.0-514.6.1.el7.x86_64 ([电子邮件保护]) (gcc 版本 4.8.5 20150623 (Red Hat 4.8.5-11) (GCC) ) conda 4.5.11 jupyter notebook 5.7.2

答案1

问题是分配给 Home 的磁盘空间配额已超出。检查方法如下：

du --si -s $HOME

结果，Jupyter 无法写入“/home/user/.local/share/jupyter/runtime/kernel-7fc2dae5-da71-4ce3-889f-de615073dd51.json”，必须清理主目录。
