I've written something in TensorFlow that makes use of some nice group theory functions that work very easily in Sage (and seem prohibitively difficult to code from scratch). However, I can't get TensorFlow and Sage to work together. Each works on its own, but I think they rely on different Python versions and therefore won't run together. I think Sage uses Python 2.6 and TensorFlow 2.7.
 
Specifically, I can make a small Python script test.py that uses some Sage functions and run it using
 
 
sage --python test.py
 
 
and it runs with no problem. But trying to import the TensorFlow module in test.py throws an error saying the tensorflow module doesn't exist. Similarly, I get errors trying to import sage.all inside my .py script that uses TensorFlow. So I can neither add TensorFlow to Sage nor add Sage to Tensorflow.
 
I first encountered this problem in Sage 6.10 and upgrading to Sage 7.0 hasn't helped.
 
I'm not sure if this is relevant, but if I fire up normal Python (the kind TensorFlow uses), I get this:
 
 
from sage.env import SAGE_LOCAL
 
SAGE_LOCAL
 
 
which outputs '$SAGE_ROOT/local'.
 
However if I fire up Sage first I get this:
 
 
sage
  SAGE_LOCAL
 
 
which outputs ''/usr/lib/sagemath/local'.
 
Any possible workaround?
 
Thanks!

The Python version shouldn't be the problem: 
$ sage -ipython
Python 2.7.9 (default, Oct 13 2015, 12:06:06) 
Type "copyright", "credits" or "license" for more information.

Here's something NOT to do (yet):
 
$ sage -pip install https://storage.googleapis.com/tensorflow/mac/tensorflow-0.7.1-cp27-none-any.whl
 
Even though this "works", it also had several worrying messages about upgrading numpy and six, which completely broke the numpy part of my Sage installation.  This was with Sage-6.9.
 
Which means you have to make sure you have a Sage that has the right versions of Numpy and six.  With the latest development version, we do, apparently:
 
$ ./sage -pip install https://storage.googleapis.com/tensorflow/mac/tensorflow-0.7.1-cp27-none-any.whl
Collecting tensorflow==0.7.1 from https://storage.googleapis.com/tensorflow/mac/tensorflow-0.7.1-cp27-none-any.whl
  Using cached https://storage.googleapis.com/tensorflow/mac/tensorflow-0.7.1-cp27-none-any.whl
Requirement already satisfied (use --upgrade to upgrade): six>=1.10.0 in ./local/lib/python2.7/site-packages/six-1.10.0-py2.7.egg (from tensorflow==0.7.1)
Collecting protobuf==3.0.0b2 (from tensorflow==0.7.1)
  Using cached protobuf-3.0.0b2-py2.py3-none-any.whl
Collecting wheel (from tensorflow==0.7.1)
  Using cached wheel-0.29.0-py2.py3-none-any.whl
Requirement already satisfied (use --upgrade to upgrade): numpy>=1.10.1 in ./local/lib/python2.7/site-packages (from tensorflow==0.7.1)
Requirement already satisfied (use --upgrade to upgrade): setuptools in ./local/lib/python2.7/site-packages/setuptools-20.1.1-py2.7.egg (from protobuf==3.0.0b2->tensorflow==0.7.1)
Installing collected packages: protobuf, wheel, tensorflow
Successfully installed protobuf-3.0.0b2 tensorflow-0.7.1 wheel-0.29.0
You are using pip version 8.0.2, however version 8.1.0 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
 
And then I don't get any failures.  
 
So one has to be careful, but apparently it's possible.  However, you definitely have to use it from "within" Sage; Sage-as-distribution wouldn't allow you to use your other tensorflow with it.
