[theano-users] Replace a Shared Variable by a scalar

[d***@gmail.com]

Hello,

How can I replace a shared variable by a scalar in a graph? I am in
particular interested in replacing it by its current value. For instance,
say I have

z = T.scalar('z')
x = theano.shared(1.0, 'x')
y = z + x

I would like to evaluate x in the above graph, so as to end up with a
Tensor Variable y

y = z + 1.0

which does not depend anymore on any Shared Variable. How can I do this?

Thanks!

When you do y=... You don't replace y. Theano create a new node (a Python
object), and assign it to a Python variable y.

It is the same as if you named the second variable y2.

I don't understand what you want to do, so I can't be more precise.
