tf.keras.backend.in_train_phase
Selects x in train phase, and alt otherwise.
tf.keras.backend.in_train_phase(
x, alt, training=None
)
Note that alt should have the same shape as x.
| Arguments | |
|---|---|
x |
What to return in train phase (tensor or callable that returns a tensor). |
alt |
What to return otherwise (tensor or callable that returns a tensor). |
training |
Optional scalar tensor (or Python boolean, or Python integer) specifying the learning phase. |
| Returns | |
|---|---|
Either x or alt based on the training flag. the training flag defaults to K.learning_phase(). |
