import

theano.tensor as T

from

theano import function

theano import Param

theano import pp

if

__name__ == "__main__":

x,

y , w= T.dscalars(‘x‘, ‘y‘, ‘w‘)

z

= x + y + w

f

= function([x, Param(y, default=1), Param(w, default=2, name=‘w_by_name‘)],

z)

print

f(33, 2, w_by_name=4)

pp(z)

這裡用Param給一個變量設定預設參數。
