【问题描述】：

我正在尝试让 Jupyter Notebook 与我的 Azure 数据科学 VM 一起使用，但内核无法正常工作。我使用 shellbash 安装 CNTK，它在命令中运行良好。但是，当我使用 Anaconda 或使用命令：“jupyter notebook”将其拉起时，我收到此错误：

关于如何让 python 内核与笔记本中的 CNTK 一起工作的任何建议？

【参考方案1】：

我打开终端到 CNTK-py35 目录并输入以下代码，内核开始工作了：

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 notebook 并运行

import CNTK

感谢 Levi 分享您的解决方案

【参考方案2】：

需要更多信息才能给您有意义的建议，因为我无法从屏幕转储中看到它。

能否激活 CNTK-py35 环境 如果您能够激活环境，请您从激活的环境中启动 python 内核 如果你在 python shell 中成功了，你可以运行import CNTK 如果可行，则说明您的 CNTK 安装良好。

现在您可以进入命令提示符，在 activate 环境中您可以尝试启动 jupyter notebook 环境。

【讨论】：

是的，CNTK 的安装没问题。它适用于 ipython 和命令行。但不是在 jupyer notebook 中，当我从 CNTK-py36 环境打开时，我得到内核错误： FileNotFoundError: [WinError 2] The system cannot find the file specified
