What is the eval function in theano?

This recipe explains what is eval function in theano.

Recipe Objective - What is eval function in theano?

The eval() function is used to return the actual value of theano variable instead of its name. If we try to just print the variable x, we only print its name. But if we use eval(), we get the actual square matrix that it is initialized to.

Example -

# Import library
import theano

# Creating a theano variable 'x' with value 10
x = theano.shared(10,'x')

#This will just print the variable x
x

Output -
x

# Eval function
x.eval() #This will print its actual value

Output -
array(10)

In this way, we can use eval() function to print the actual value of the variable instead of its name in theano.
