如何禁用警报，我在文档中没有找到为此的布尔参数。

import React from \'react\';\nimport Alert from \'@material-ui/lab/Alert\';\n\nexport default function SimpleAlerts() {\n  const classes = useStyles();\n\n  return (\n    <div>\n      <Alert severity="error">This is an error alert \xe2\x80\x94 check it out!</Alert>\n    </div>\n  );\n}\n

我已经安装了Anaconda，我设法启动了它，然后使用R或python，今天我再也无法启动它了，并且出现了这个错误（在管理员模式下运行该软件时，我得到了同样的错误）

An unexpected error ocurred on Navigator start-up

During handling of the above exception, another exception occurred:

断电之后我的节点去陈述下降

sinfo -a

PARTITION AVAIL  TIMELIMIT  NODES  STATE NODELIST
partMain  up      infinite      4   down* node[001-004]
part1*    up      infinite      3   down* node[002-004]
part2     up      infinite      1   down* node001

我执行这些命令

 /etc/init.d/slurm stop
 /etc/init.d/slurm start

sinfo -a

PARTITION AVAIL  TIMELIMIT  NODES  STATE NODELIST
partMain  up      infinite      4   down node[001-004]
part1*    up      infinite      3   down node[002-004]
part2     up      infinite      1   down node001

我怎么能重新启动我的节点？

sinfo -R

我不知道我用什么策略来证明这个结构.我尝试了两种方法,但我陷入了两种方法.
