Apparently, based on the error you get, you are missing install the ipykernel package, playing on google found two solutions:
1st: Using the Pip:
First make sure your Pip is in version 9.0>>
python2 -m pip --version
Then use the commands:
python2 -m pip install ipykernel
python2 -m ipykernel install --user
2nd: Using the virtual environment and Conda
conda create -n ipykernel_py2 python=2 ipykernel
source activate ipykernel_py2 # On Windows, remove the word 'source'
python -m ipykernel install --user
