在工作区中运行 Jupyter 笔记本Run Jupyter Notebooks in your workspace

了解如何直接在 Azure 机器学习工作室的工作区中运行 Jupyter 笔记本。Learn how to run your Jupyter notebooks directly in your workspace in Azure Machine Learning studio. 用户不但可以在工作区中启动 JupyterJupyterLab,还可以直接编辑和运行笔记本。While you can launch Jupyter or JupyterLab, you can also edit and run your notebooks without leaving the workspace.

有关如何创建和管理文件(包括笔记本)的信息,请参阅在工作区中创建和管理文件For information on how to create and manage files, including notebooks, see Create and manage files in your workspace.


编辑笔记本Edit a notebook

若要编辑笔记本,请打开位于工作区“用户文件”部分的任何笔记本。To edit a notebook, open any notebook located in the User files section of your workspace. 单击要编辑的单元格。Click on the cell you wish to edit. 如果本部分中没有任何笔记本,请参阅在工作区中创建和管理文件If you don't have any notebooks in this section, see Create and manage files in your workspace.

你可以在不连接到计算实例的情况下编辑笔记本。You can edit the notebook without connecting to a compute instance. 要运行笔记本中的单元格时,请选择或创建一个计算实例。When you want to run the cells in the notebook, select or create a compute instance. 如果选择一个已停止的计算实例,则在你运行第一个单元时,该计算实例会自动启动。If you select a stopped compute instance, it will automatically start when you run the first cell.

如果计算实例正在运行,还可以在任何 Python Notebook 中使用由 Intellisense 提供支持的代码完成功能。When a compute instance is running, you can also use code completion, powered by Intellisense, in any Python Notebook.

另外,还可以从笔记本工具栏中启动 Jupyter 或 JupyterLab。You can also launch Jupyter or JupyterLab from the Notebook toolbar. Azure 机器学习不提供来自 Jupyter 或 JupyterLab 的更新,也不修复其中的 bug,因为这些开源产品不在 Microsoft 支持的范围内。Azure Machine Learning does not provide updates and fix bugs from Jupyter or JupyterLab as they are Open Source products outside of the boundary of Microsoft Support.

焦点模式Focus mode

使用焦点模式展开当前视图,以便将焦点放在活动的选项卡上。Use focus mode to expand your current view so you can focus on your active tabs. 焦点模式将隐藏笔记本文件资源管理器。Focus mode hides the Notebooks file explorer.

  1. 在终端窗口工具栏中,选择“焦点模式”以打开焦点模式。In the terminal window toolbar, select Focus mode to turn on focus mode. 根据窗口宽度的不同,它可能位于工具栏的“…”菜单项下。Depending on your window width, this may be located under the ... menu item in your toolbar.

  2. 在焦点模式下,通过选择“标准视图”返回到标准视图。While in focus mode, return to the standard view by selecting Standard view.


使用 IntelliSenseUse IntelliSense

IntelliSense 是一个代码完成辅助插件,其中包括许多功能:“列出成员”、“参数信息”、“快速信息”和“完成单词”。IntelliSense is a code-completion aid that includes a number of features: List Members, Parameter Info, Quick Info, and Complete Word. 这些功能可帮助你详细了解所使用的代码、跟踪正在键入的参数,只需几次击键即可添加对属性和方法的调用。These features help you to learn more about the code you're using, keep track of the parameters you're typing, and add calls to properties and methods with only a few keystrokes.

键入代码时,请使用“Ctrl+空格键”来触发 IntelliSense。When typing code, use Ctrl+Space to trigger IntelliSense.

清理笔记本(预览版)Clean your notebook (preview)


收集功能目前为公共预览版。The gather feature is currently in public preview. 该预览版在提供时没有附带服务级别协议,建议不要将其用于生产工作负载。The preview version is provided without a service level agreement, and it's not recommended for production workloads. 某些功能可能不受支持或者受限。Certain features might not be supported or might have constrained capabilities.

在创建笔记本的过程中,通常最终会得到用于数据浏览或调试的单元格。Over the course of creating a notebook, you typically end up with cells you used for data exploration or debugging. “收集”功能会帮助你生成一个没有这些无关单元格的纯净笔记本。The gather feature will help you produce a clean notebook without these extraneous cells.

  1. 运行所有笔记本单元格。Run all of your notebook cells.

  2. 选择特定的单元格,其中包含的代码是你希望新笔记本运行的。Select the cell containing the code you wish the new notebook to run. 例如,用于提交试验的代码,或者用于注册模型的代码。For example, the code that submits an experiment, or perhaps the code that registers a model.

  3. 选择单元格工具栏上出现的“收集”图标。Select the Gather icon that appears on the cell toolbar.


  4. 输入新的“已收集”笔记本的名称。Enter the name for your new "gathered" notebook.

新笔记本只包含代码单元格,所有单元格都需要生成与你选择用于收集的单元格相同的结果。The new notebook contains only code cells, with all cells required to produce the same results as the cell you selected for gathering.

将笔记本保存并设置检查点Save and checkpoint a notebook

当你创建一个 ipynb 文件时,Azure 机器学习会创建一个检查点文件。Azure Machine Learning creates a checkpoint file when you create an ipynb file.

在笔记本工具栏中,选择“菜单”,然后选择“文件”>“保存并设置检查点”以手动保存笔记本,它会添加与笔记本关联的检查点文件。In the notebook toolbar, select the menu and then File>Save and checkpoint to manually save the notebook and it will add a checkpoint file associated with the notebook.


每个笔记本每隔 30 秒会自动保存一次。Every notebook is autosaved every 30 seconds. 自动保存仅更新初始 ipynb 文件,而不更新检查点文件。Autosave updates only the initial ipynb file, not the checkpoint file.

在“笔记本”菜单中选择“检查点”以创建命名检查点,并将笔记本还原为已保存的检查点。Select Checkpoints in the notebook menu to create a named checkpoint and to revert the notebook to a saved checkpoint.

导出笔记本Export a notebook

在笔记本工具栏中选择菜单,然后选择“导出为”,以任一受支持类型导出笔记本:In the notebook toolbar, select the menu and then Export As to export the notebook as any of the supported types:

  • 笔记本Notebook

导出的文件保存在计算机上。The exported file is saved on your computer.

运行笔记本或 Python 脚本Run a notebook or Python script

若要运行笔记本或 Python 脚本,请先连接到正在运行的计算实例To run a notebook or a Python script, you first connect to a running compute instance.

  • 如果没有计算实例,请使用以下步骤创建一个计算实例:If you don't have a compute instance, use these steps to create one:

    1. 在笔记本或脚本工具栏中,选择“计算”下拉列表右侧的“+ 新建计算”。In the notebook or script toolbar, to the right of the Compute dropdown, select + New Compute. 它可能位于“...”菜单下,具体取决于屏幕大小。Depending on your screen size, this may be located under a ... menu. 创建新计算
    2. 为计算命名,并在“虚拟机大小”中选择一个大小。Name the Compute and choose a Virtual Machine Size.
    3. 选择“创建”。Select Create.
    4. 计算实例自动连接到文件。The compute instance is connected to the file automatically. 现在可以使用计算实例左侧的工具来运行笔记本单元格或 Python 脚本。You can now run the notebook cells or the Python script using the tool to the left of the compute instance.
  • 如果有已停止的计算实例,请选择“计算”下拉列表右侧的“开始计算”。If you have a stopped compute instance, select Start compute to the right of the Compute dropdown. 它可能位于“...”菜单下,具体取决于屏幕大小。Depending on your screen size, this may be located under a ... menu.


只有本人可以查看和使用自己创建的计算实例。Only you can see and use the compute instances you create. 用户文件与 VM 分开存储,并在工作区中的所有计算实例之间共享。Your User files are stored separately from the VM and are shared among all compute instances in the workspace.

查看日志和输出View logs and output

使用笔记本小组件可以查看运行进度和日志。Use Notebook widgets to view the progress of the run and logs. 小组件具有异步性,在训练结束之前,它会一直提供更新。A widget is asynchronous and provides updates until training finishes. Jupyter 和 JupterLab 也支持 Azure 机器学习小组件。Azure Machine Learning widgets are also supported in Jupyter and JupterLab. 屏幕截图:Jupyter 笔记本小组件

探究笔记本中的变量Explore variables in the notebook

在笔记本工具栏上,使用“变量资源管理器”工具显示已在笔记本中创建的所有变量的名称、类型、长度和示例值。On the notebook toolbar, use the Variable explorer tool to show the name, type, length, and sample values for all variables that have been created in your notebook.


选择此工具可显示“变量资源管理器”窗口。Select the tool to show the variable explorer window.


在笔记本工具栏上,使用“目录”工具显示或隐藏目录。On the notebook toolbar, use the Table of contents tool to display or hide the table of contents. 启动带标题的 Markdown 单元格,以将其添加到目录中。Start a markdown cell with a heading to add it to the table of contents. 单击表中的某个条目可滚动到笔记本中的相应单元格。Click on an entry in the table to scroll to that cell in the notebook.


更改笔记本环境Change the notebook environment

使用笔记本工具栏可以更改笔记本的运行环境。The Notebook toolbar allows you to change the environment on which your Notebook runs.
