問題：importing tensotflow in python cli 中正常 但在jupyter中缺給出了以下錯誤：

ImportError: cannot import name pywrap_tensorflow

Importing tensorflow in jupyter notebook (Not working Error):

 import tensorflow as tf

 

ImportErrorTraceback (most recent call last) in ()  2 import cv2 as cv2  3 from PIL import Image ----> 4 import tensorflow as tf  5 #'/home/ubuntu/.local/lib/python2.7/site-packages/tensorflow' /home/ubuntu/.local/lib/python2.7/site-packages/tensorflow/__init__.py in ()  21 from __future__ import print_function  22 ---> 23 from tensorflow.python import *  24  25 /home/ubuntu/.local/lib/python2.7/site-packages/tensorflow/python/__init__.py in ()  47 _default_dlopen_flags = sys.getdlopenflags()  48 sys.setdlopenflags(_default_dlopen_flags | ctypes.RTLD_GLOBAL) ---> 49 from tensorflow.python import pywrap_tensorflow  50 sys.setdlopenflags(_default_dlopen_flags)  51 ImportError: cannot import name pywrap_tensorflow

Importing tensorflow in CLI python (Working):

$ python

Python 2.7.12 (default, Jul 1 2016, 15:12:24)
[GCC 5.4.0 20160609] on linux2

>>> 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’]

問題調查:

檢查 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

檢查 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

其餘 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’]

解決方案:

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.
