Flatten
classkeras.layers.Flatten(data_format=None, **kwargs)
Flattens the input. Does not affect the batch size.
Note: If inputs are shaped (batch,)
without a feature axis, then
flattening adds an extra channel dimension and output shape is (batch, 1)
.
Arguments
"channels_last"
(default) or
"channels_first"
. The ordering of the dimensions in the inputs.
"channels_last"
corresponds to inputs with shape
(batch, ..., channels)
while "channels_first"
corresponds to
inputs with shape (batch, channels, ...)
.
When unspecified, uses image_data_format
value found in your Keras
config file at ~/.keras/keras.json
(if exists). Defaults to
"channels_last"
.Example
>>> x = keras.Input(shape=(10, 64))
>>> y = keras.layers.Flatten()(x)
>>> y.shape
(None, 640)
