如何在 Azure 机器学习工作室的 jupyter notebook 中安装 TensorFlow

Question

我正在尝试测试 Azure 机器学习工作室。

我想使用 TensorFlow，但 Jupyter notebook 上没有安装它。

如何在笔记本上使用 TensorFlow、Theano、Keras 等机器学习库？

我试过这个：

!pip install tensorflow

但是，我得到如下错误：

如你所见，活动用户无权写入 Azure 机器学习工作室笔记本中的 site-packages 目录。您可以尝试将软件包安装到您具有写入权限的另一个目录（如默认工作目录）并从那里导入，但我建议使用以下 lower-hassle 选项。

Azure Notebooks is a separate Jupyter Notebook service that will allow you to install tensorflow, theano, and keras. Like the notebooks in AML Studio, these notebooks will persist in your account. The primary downside is that if you want to access your workspace through e.g. the Python azureml package, you'll need to provide your workspace id/authorization token 建立连接。（在 Azure ML Studio 中，这些值是从当前工作区自动加载的。）否则我相信 Azure Notebooks 可以做你习惯在 AML Studio 中做的所有事情。
