Problem: importing tensotflow in python cli works fine but in jupyter it gives the following error:

ImportError: cannot import name pywrap_tensorflow

Importing tensorflow in jupyter notebook (Not working Error):

 import tensorflow as tf

Importing tensorflow in CLI python (Working):

>>> import tensorflow
>>> import tensorflow as tf
>>> print(tf)
<module ‘tensorflow’ from ‘/home/ubuntu/.local/lib/python2.7/site-packages/tensorflow/__init__.pyc’>
>>> help(tf)

>>> print tf.__version__
0.11.0rc2
>>> print tf.__path__
[‘/home/ubuntu/.local/lib/python2.7/site-packages/tensorflow’]

Question investigation:

Check the location of the tensorflow package:

$ ls /home/ubuntu/.local/lib/python2.7/site-packages/tensorflow/
contrib core examples include init.py init.pyc models python tensorboard tools

Check the location of jupyter

$ ps -ef | grep jupyter
ubuntu 1347 1 0 Nov11 ? 00:00:46 /usr/bin/python /usr/local/bin/jupyter-notebook –no-browser –ip=* –port=8888

Location of other python packages: 

>> import sklearn
>>> print(sklearn.__path__)
[‘/home/ubuntu/.local/lib/python2.7/site-packages/sklearn’]
>>> import mxnet
>>> print(mxnet.__path__)
[‘/usr/local/lib/python2.7/dist-packages/mxnet-0.7.0-py2.7.egg/mxnet’]

solution:

1. If you have installed tensorflow while jupyter is running, importing tensorflow will not work in jupyter (check if it works on python CLI). You just need to Restart jupyter notebook and it should work.
2. If you have problem in both jupyter and python CLI, then you just need to start jupyter from other location.
