在azure批处理节点中安装python包

如何在azure批处理节点中安装python包，如pip安装azure存储blob。我试图在start task中编写该命令，但导致stark任务失败？

定义池时，必须指定池启动任务。创建并加入池时（或重新启动、重新映像时），此启动任务将在每个节点上运行

您可以在游泳池下的控制台中执行此操作。或者，如果您使用了Python，请这样做（这是一个示例，根据需要进行调整！）。看看task_commands变量是如何定义的（需要curl）：

Stack Overflow是一个关于编程和开发问题的网站。这个问题似乎离题了，因为它与编程或开发无关。请参见帮助中心中的。也许是或者会是一个更好的问题。我不同意@jww，Azure的用法是编程，尤其是批处理（如果用户使用CLI来定义其infra，而不仅仅是web界面的话）。我一直想知道，在SO中是否存在与开发软件安装相关的问题？通过将python编译为.exe来修复它。感谢您的回复：）我想知道如何在节点上运行自定义python脚本。文档中的示例仅显示如何使用系统命令（如

cat

或Ubuntu pkg，如

ffmpeg

），而不是您自己的python代码。现在，我了解了如何在创建池时使用

task\u命令来上传我们自己的脚本，然后在任务中使用它。谢谢。
