Cannot import Tensorflow in ipython

Question

I have tensorflow version 1.0.0 non-GPU version on my macbook pro Yosemite. It is installed in a virtualenv, and I have python 2.7. I have six version 1.4.1. When I do python on the command line and import six, it works fine. But when I enter 'ipython' and import tensorflow, I see this error:

I tried upgrading six and I am still seeing version 1.4.1. Is six the problem here? if not what is?

from this i cant tell what the error is: what is the error message. — parsethis

This is only part of the error message. It cuts off abruptly. — user2357112

What six version are you on? I've a similar env and I'm on six==1.10.0, tensorflow==1.0.0, Python 2.7.12 — ruoho ruotsi

It seems that there's a number of things tangled. I'm using Anaconda2 with six==1.10.0, tensorflow==1.0.0 and Python 2.7.12. A quick experiment would be to install Anaconda2 (i.e. with python2.7) then pip install TF and other dependencies and try it out.

The Anaconda installation is self-contained, so that you won't be affected by other system-wide issues. I just did it by running /Users/myusername/anaconda2/bin/ipython

My guess is that you need to install iPython from within the virtual environment. if you haven't done that, ipython will use the vanilla interpreter even though you are in a virtual environment.

when I try to pip install ipython inside my virtualenv, it says requirements already satisfied though?

Colin Nichols Over a year ago

how did you create and activate the virtual environment? what is the output of " which ipython" and "which pip"? what are the outputs of those commands when you are outside of the virtual environment?

xiaolingxiao Over a year ago

I did source ~/tensorflow/bin/activate, which ipython is at /usr/local/bin/ipython, which pip is /Users/lingxiao/tensorflow/bin/pip. Outside of virtual env ipython is at /usr/local/bin/ipython, pip is at /usr/local/bin/pip

Colin Nichols Over a year ago

which ipython should also return a path within the virtual environment, similar to pip. I would try uninstalling and reinstalling ipython from within the virtual environment. And if that doesn't work, it might be time to blow away the virtual environment and make a new one.

xiaolingxiao Over a year ago

it's funny because which ipython inside the environment does not return a path from within, it's at usr/local/bin/ipython. When I try to uninstall it from inside the virtualenv, I get Not uninstalling ipython at /Library/Python/2.7/site-packages, outside environment /Users/lingxiao/tensorflow
