I'm a bit confused how `reg_lambda` works.
It is not defined as tf.placeholder() then how we can change this variable inside tensorflow without feed_dict{}.

The scalar is exception here?

How about the code below? will it work as same?

LAMBDA = tf.placeholder(tf.float32)

cost = tf.div(, ....)

..., feed_dict={X: x_train, Y: y_train, LAMBDA: reg_lambda})
