训练yolov7，device输入参数默认是cpu，在cpu上训练。想改用GPU，device参数改成0，但是notebook运行报了错：请问可怎么解决？

命令和报错信息： (python-3.7.10) [ma-user work]$ma-cli image build .ma/customize_from_ubuntu_18.04_to_modelarts/Dockerfile -swr hw03426922/only-conda:0.0.1 [+] Building 0.0s (0/0) error: failed to get status: rpc error: code = Unavailable desc = connection error: desc = "transport: error while dialing: dial tcp 127.0.0.1:1234: connect: connection refused"   Failed to build image, for details, see /home/ma-user/work/.ma/customize_from_ubuntu_18.04_to_modelarts/build_log.log. [ FAILED ] Build image hw03426922/only-conda:0.0.1 failed! 这是为什么呢？

在Notebook里开了一个teminal, 然后打开了vim用Ctrl-F是往下翻页当想用Ctrl-B向上翻页时，发现是切换文件浏览器的隐藏和显示，所以，notebook里如何修改Ctrl-B快捷键的行为？

本地Anaconda使用pip install jupyterlab后使用jupyter-lab打开窗口创建Terminal出现错误Launcher Error、Unhandled error、Dismiss解决方案通过查询Anaconda窗口信息发现报错如下：Traceback (most recent call last):      File "e:\anaconda3\envs\pytorch1.6.0\lib\site-packages\tornado\web.py", line 1702, in _execute        result = method(*self.path_args, **self.path_kwargs)      File "e:\anaconda3\envs\pytorch1.6.0\lib\site-packages\tornado\web.py", line 3173, in wrapper        return method(self, *args, **kwargs)      File "e:\anaconda3\envs\pytorch1.6.0\lib\site-packages\jupyter_server\terminal\api_handlers.py", line 26, in post        name, _ = self.terminal_manager.new_named_terminal(**data)      File "e:\anaconda3\envs\pytorch1.6.0\lib\site-packages\terminado\management.py", line 319, in new_named_terminal        term = self.new_terminal(**kwargs)      File "e:\anaconda3\envs\pytorch1.6.0\lib\site-packages\terminado\management.py", line 171, in new_terminal        pty = PtyProcessUnicode.spawn(argv, env=env, cwd=options.get('cwd', None))      File "e:\anaconda3\envs\pytorch1.6.0\lib\site-packages\winpty\ptyprocess.py", line 89, in spawn        'executable: %s.' % command    FileNotFoundError: The command was not found or was not executable: powershell.exe.可以发现报错的原因是JupyterLab在创建Ternimal时无法定位到PowerShell。为此，我通过CMD启用PowerShell仍然失败，如下所示：因此怀疑时是环境变量中缺少`PowerShell`路径，因此我找到`PowerShell`路径并添加至环境变量，如下所示完成后在CMD中输入PowerShell即可进入PowerShell模式此时打开Anaconda启动JupyterLab，即可正常启动Terminal，如下所示：总结如果在Win10平台使用JupyterLab无法正常启动Terminal且报错为FileNotFoundError: The command was not found or was not executable: powershell.exe.，只需要在环境变量中添加PowerShell路径

如题，notebook好像没有办法自己装驱动，非常感谢

小白求助，使用notebook老是碰到以下问题

如图如图如图如图如图

使用pip install时出现“没有空间”的错误

如何在Notebook中安装外部库？

在Notebook中，如何访问其他帐号的OBS桶？

Notebook可以访问OBS中的文件，如果对文件进行重命名？

Notebook停止或者重启后，“/cache”下的文件还存在么？

报错内存已满或者“CUDA error: out of memory”怎么办？ 有没有什么办法？

kernel Restarting怎么回事?有什么方法？
