azure - Jupyter 笔记本内核上的 CNTK 无法工作

Question

我正在尝试让 Jupyter Notebook 与我的 Azure 数据科学 VM 配合使用，但内核无法正常工作。我使用 shellbash 安装 CNTK，并且它可以通过类似的命令运行良好。但是，当我使用 Anaconda 或使用命令“jupyter Notebook”将其拉出时，我收到此错误:

关于如何让 python 内核在笔记本中与 CNTK 一起工作有什么建议吗？

Answer 1

我打开 CNTK-py35 目录的终端并输入以下代码，内核开始工作并使其正常工作:

conda create -n py35 python=3.5
activate py35
conda install notebook ipykernel
ipython kernel install --user --name=python3.5

然后我从 Anaconda 内部打开 jupyter 笔记本并运行

import CNTK
