Getting Syntax error and deprecated TF function

[fishandchipsing]

Hi Dmitry,
thanks for putting this together, this is exactly what I was looking for an experiment!
I am definitely a beginner in this, but I was trying to run your example and I get a Syntax error on the Optimise kernel and in the Output in the print as now you have to add parenthesis.

File "<ipython-input-16-9eb962c6044b>", line 50
    print 'Final loss:', loss.eval()
                      ^
SyntaxError: invalid syntax

I also figured out that tf.initialize_all_variables() is now deprecated and so changed it to tf.global_variables_initializer()

Then it all works well!
Thanks!
