Whats going on here? Isn’t variable an already defined attribute?

My code:

W1 = tf.variable(initializer(shape=(25,12288)))
b1 = tf.variable(initializer(shape=(25,1)))
W2 = tf.varaible(initializer(shape=(12,25)))
b2 = tf.variabel(initializer(shape=(12,1)))
W3 = tf.variable(initializer(shape=(6,12)))
b3 = tf.variable(initializer(shape=(6,1)))

ERROR message:

AttributeError Traceback (most recent call last)

AttributeError: module ‘tensorflow’ has no attribute ‘variable’

Hi @Zekromblue , consider that python is as Case Sensitive language. Check how are you calling the different methods.

Hmm, I still cant see what I’m doing wrong

wait I think I got it, needs to be capital V in variable. Thank you so much!

Ah but looks like changing that didnt work either. :confused: sill getting the same error.
module ‘tensorflow’ has no attribute ‘Varaible’

It worked! Thank you for the resolution.
