问题：importing tensotflow in python cli 中正常 但在jupyter中缺给出了如下错误：

ImportError: cannot import name pywrap_tensorflow

Importing tensorflow in jupyter notebook (Not working Error):

 import tensorflow as tf

ImportError: cannot import name pywrap_tensorflow

Importing tensorflow in CLI python (Working):

$ python

Type “help”, “copyright”, “credits” or “license” for more information.

>>> 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’]

问题调查:

检查 tensorflow包的位置:

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

检查 jupyter的位置

$ 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

其他 python 包的位置: 

>> 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’]

解决方案:

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.
