CNTK on Jupyter notebook kernal not working

Question

I am trying to get Jupyter Notebook to work with my Azure data Science VM and the kernel in not working. I installes CNTK using the shellbash and it works well from the command like. However when I pull it up using Anaconda or with the command: "jupyter notebook" I get this error:

Any advice on how to get the python kernel to work with CNTK in the notebook?

I opened up the terminal to the CNTK-py35 directory and entered the following code and the kernel started working got it working:

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

Then I opened jupyter notebook from inside Anaconda and ran

import CNTK

Need a bit more information to give you meaningful advice, as I cannot see it from the screen dump.

Are you able to activate CNTK-py35 environment
If you are able to activate the environment, could you please start the python kernel from within the activated environment
If you are successful with that from within the python shell are you able to run import CNTK
If that works, that means your CNTK installation is good.

Now you can go the command prompt, from within the activate environment can you try starting the jupyter notebook environment.

You can find more information along these lines for the python setup, at this link: https://github.com/Microsoft/CNTK/wiki/Setup-Windows-Python

Yes the installation of CNTK is fine. It works in ipython and in the command line. But not in jupyer notebook which when I open from the CNTK-py36 environment I get kernal error: FileNotFoundError: [WinError 2] The system cannot find the file specified — Levi Brackman, Feb 27 '17 at 17:29
