jupyter notebook show enviornment
1. Anaconda version:
my experience is only install nb_conda is enough
conda install nb_conda
2. for normal pyhton version, you need to install ipykernel in each enviornment. (Notice: following code is example for mac and linux system.)
source activate my_environment pip install ipykernel
