python - import error OpenCV on Jupyter Notebook (but it works in Ipython on Terminal..) -

i'm having interesting error import cv2 in ipython on terminal cannnot import library on jupyter notebook. checked kernel i'm using same kernel (anaconda python2.7)

would has idea how fix this?

error:     importerrortraceback (most recent call last)     <ipython-input-2-52da0154cfe4> in <module>()     ----> 1 import cv2           2 import numpy np      importerror: no module named cv2

$which python

/users/kn/anaconda2/envs/python2/bin/python 

create one-line opencv.pth file under /users/kn/anaconda2/lib/python2.7/site-packages.

the content of file like:

/usr/local/opt/opencv3/lib/python2.7/site-packages 

this append opencv3 path under conda environments permanently. think it's better make cv2 available python2 environment.
