Interactive session

Interactive sessions are another way to use a session. Go ahead and define one:

In [1]:
import tensorflow as tf
sess = tf.InteractiveSession()

We have a matrix we want to invert:

In [2]:
x = tf.constant([[1., 2.]])
neg_op = tf.negative(x)

Since we're using an interactive session, we can just call the eval() method on the op.

In [3]:
result = neg_op.eval()


[[-1. -2.]]

That code's a little cleaner when using Jupyter notebooks (like this one).

Don't forget to close the session:
