Permute layer


Permute class

keras.layers.Permute(dims, **kwargs)

Permutes the dimensions of the input according to a given pattern.

Useful e.g. connecting RNNs and convnets.


  • dims: Tuple of integers. Permutation pattern does not include the batch dimension. Indexing starts at 1. For instance, (2, 1) permutes the first and second dimensions of the input.

Input shape


Output shape

Same as the input shape, but with the dimensions re-ordered according to the specified pattern.


>>> x = keras.Input(shape=(10, 64))
>>> y = keras.layers.Permute((2, 1))(x)
>>> y.shape
(None, 64, 10)
