如何在Azure机器学习工作室的jupyter笔记本中安装TensorFlow

Question

我正在尝试测试Azure机器学习工作室。

我想使用TensorFlow，但它没有安装在Jupyter笔记本上。

我如何在笔记本上使用一些机器学习库，如TensorFlow，Theano，Keras，...？

我试过这个：

!pip install tensorflow 

但是，我得到了错误如下：

正如您所注意到的，活动用户没有权限写入Azure Machine Learning Studio笔记本中的站点包目录。您可以尝试将包安装到另一个具有写入权限的目录（如默认的工作目录）并从那里导入，但我建议使用以下简单的选项。

Azure Notebook是一个单独的Jupyter Notebook服务，它允许你安装tenstorflow、theano和keras。与AML Studio中的笔记本一样，这些笔记本将保留在您的帐户中。主要的缺点是，如果您想通过Pythonazureml包访问您的工作区，您需要提供您的工作区id/授权令牌来设置连接。（在Azure ML Studio中，这些值会从当前工作区自动加载。）否则，我相信Azure笔记本可以仅在AML Studio中执行您习惯执行的所有操作。
