Description

The operator create_dl_layer_permutationcreate_dl_layer_permutationCreateDlLayerPermutationCreateDlLayerPermutationcreate_dl_layer_permutation creates a permutation layer whose handle is returned in DLLayerPermutationDLLayerPermutationDLLayerPermutationDLLayerPermutationdllayer_permutation.

The parameter DLLayerInputDLLayerInputDLLayerInputDLLayerInputdllayer_input determines the feeding input layer and expects the layer handle as value.

The parameter LayerNameLayerNameLayerNamelayerNamelayer_name sets an individual layer name. Note that if creating a model using create_dl_modelcreate_dl_modelCreateDlModelCreateDlModelcreate_dl_model each layer of the created network must have a unique name.

The parameter PermutationPermutationPermutationpermutationpermutation determines the new order of the axes of DLLayerInputDLLayerInputDLLayerInputDLLayerInputdllayer_input, to which the input axes should be permuted.

PermutationPermutationPermutationpermutationpermutation has the form [index width, index height, index depth, index batch], where the indices are corresponding to the dimensions of the input. For example, [0, 1, 3, 2] leads to swapping the depth and the batch axes. Therefore, each index must be unique and be taken from the set '{0, 1, 2, 3}'"{0, 1, 2, 3}""{0, 1, 2, 3}""{0, 1, 2, 3}""{0, 1, 2, 3}".

Using a CPU device, for some values of PermutationPermutationPermutationpermutationpermutation the internal code can not be optimized which can lead to an increased runtime. In this case, the layer parameter 'fall_back_to_baseline'"fall_back_to_baseline""fall_back_to_baseline""fall_back_to_baseline""fall_back_to_baseline" is set to 'true'"true""true""true""true".

The following generic parameters GenParamNameGenParamNameGenParamNamegenParamNamegen_param_name and the corresponding values GenParamValueGenParamValueGenParamValuegenParamValuegen_param_value are supported:

'is_inference_output'"is_inference_output""is_inference_output""is_inference_output""is_inference_output":
