tf.keras.backend.ones
Instantiates an all-ones variable and returns it.
tf.keras.backend.ones(
shape, dtype=None, name=None
)
Arguments |
shape |
Tuple of integers, shape of returned Keras variable. |
dtype |
String, data type of returned Keras variable. |
name |
String, name of returned Keras variable. |
Returns |
A Keras variable, filled with 1.0 . Note that if shape was symbolic, we cannot return a variable, and will return a dynamically-shaped tensor instead. |
Example:
from keras import backend as K
kvar = K.ones((3,4))
K.eval(kvar)
array([[ 1., 1., 1., 1.],
[ 1., 1., 1., 1.],
[ 1., 1., 1., 1.]], dtype=float32)
