tf.keras.backend.batch_flatten(
    x
)

In other words, it flattens each data samples of a batch.

Arguments
x	A tensor or variable.

Returns
A tensor.

Examples:

Flattening a 3D tensor to 2D by collapsing the last dimension.

from tensorflow.keras import backend as K
x_batch = K.ones(shape=(2, 3, 4, 5))
x_batch_flatten = K.batch_flatten(x_batch)
K.int_shape(x_batch_flatten)
