tf.keras.backend.batch_flatten

TensorFlow 1 version View source on GitHub

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

tf.keras.backend.batch_flatten(
    x
)

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.

    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)
        (2, 60)
