tf.keras.backend.batch_flatten

Turn a nD tensor into a 2D tensor with same 0th dimension.

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

x A tensor or variable.

A tensor.

Examples:

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

x_batch = tf.keras.backend.ones(shape=(2, 3, 4, 5))
x_batch_flatten = batch_flatten(x_batch)
tf.keras.backend.int_shape(x_batch_flatten)
(2, 60)
