No module named tensor flow — iPython notebook

问题:

I understand this may be an old question, but still I cannot find solution from off-the-shelf Q$A. Here is the problem:

I am following Udacity "Machine Learning" and its assignments, and need use iPythonNotebook & tensorflow. Details : https://github.com/Omarito2412/udacity-deeplearning

Assignment2 requires tensorflow. BTW, I already installed Anaconda, already made tensorflow working on Pycharm on the same computer which is Macbook, but do not know how to make it work on iPythonNotebook environment.

The codes are quite simple, as follows:

import numpy as np
import tensorflow as tf
from six.moves import cPickle as pickle
from six.moves import range

---

and the error message is as follows:

ImportError                               Traceback (most recent call last)
<ipython-input-1-0970743dd90d> in <module>()
      2 # before proceeding further.
      3 import numpy as np
----> 4 import tensorflow as tf
      5 from six.moves import cPickle as pickle
      6 from six.moves import range

ImportError: No module named tensorflow

Thanks. Any suggestions ?

PS: I have this problem on two MacBooks, and both MacBooks run Pycharm+tensorflow well.

回答1:

You should deactivate and re-activate the environment

source deactivate tensorflow
source activate tensorflow

回答2:

After I tried Anaconda-installation (I was using the other installation methods, which are all shown in the link below) https://github.com/tensorflow/tensorflow/blob/master/tensorflow/g3doc/get_started/os_setup.md#anaconda-installation It worked ...

Further, on terminal activate tensorflow

>>> source activate tensorflow

before open iPython Notebook

>>> ipython notebook

At last, I have to restart my macbook to make it work....

i have missed tensorflow install (3) number below the list.. now i have solved

1. for anaconda install

2. for enviroment install https://github.com/tensorflow/tensorflow/blob/master/tensorflow/g3doc/get_started/os_setup.md#anaconda-installation

3. for tensorflow install https://github.com/conda-forge/tensorflow-feedstock

回答4:

This is likely due to an anemic environment variable, one of the library path class. I don't know how iPythonNotebook denotes the libraries it will search for files (say, $LD_LIBRARY_PATH), but I believe that you have to find it (a list of paths to libraries) and add the root directory of TensorFlow.

回答5:

More than likely either Tensorflow is not installed in the right Python environment of Conda or not installed at all. Follow the below steps:

$ conda create -n tensorflow python=3.5

Once that is done, need to activate that as below:

$ source activate tensorflow

Then when you open IPython Notebook or Spyder, it will recognize the Tensorflow.
