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 | |
