Hey Thomas,


ACK, the build flow of tensorflow (i.e. bazel) is quite WTF... they  
are basically
only supporting "toy" installations (like Ubuntu +  
user-managed/pipified python).

We now took another path and created a "package build receipt" for tensorflow
and all its dependencies which can be used by the SPACK package manager.

To use it on our production/wheezy cluster:

$ source /wang/environment/software/wheezy/spack/share/spack/setup-env.sh
$ source <(spack module loads --dependencies tensorflow)

Now it should work; to test it:

$ python -m tensorflow.models.image.mnist.convolutional

If you need other more-up-to-date versions of python packages, e.g.  
jupyter or matplotlib:

$ for pkg in py-jupyter py-matplotlib; do
       source <(spack module loads --dependencies $pkg)
   done


Cheers,
Eric
