Tensorflow installation: ImportError on sklearn - undefined symbol: PyFPE_jbuf

Following the Udacity course on Deep Learning with TensorFlow, and hit a roadblock here: https://github.com/tensorflow/tensorflow/blob/master/tensorflow/examples/udacity/1_notmnist.ipynb

I tried to get the installation running, but the initial imports didn't work out so well. Specifically, this import error on a certain file:

/tensorflow/lib/python2.7/site-packages/sklearn/linear_model/cd_fast.so

Running tensorflow in a virtualenv installation on Ubuntu 14.04, should that help.

ImportError: .../tensorflow/lib/python2.7/site-packages/sklearn/linear_model/cd_fast.so: undefined symbol: PyFPE_jbuf

Anyone here who knows how to proceed? (Maybe this is a very simple error - I'm quite the newbie to this)

UPDATE: Everything works fine when I run the iPython Notebooks from the usual terminal, as opposed to running them from the tensorflow virtual environment (as I had done when I first posted this question). I do not understand why this happened, though.

I also had trouble with sklearn in working with tensor flow. I had dowload it and install latest version manually to the TSNE module to work. Perhaps this will work for you too?

Step 1: Install Cython manually - you will version > 0.21

mkdir cython
cd cython
wget http://cython.org/release/Cython-0.24.zip
unzip Cython-0.24.zip
cd Cython-0.24
sudo python setup.py install

Step 2: Install latest version of skilearn
