描述
算子 create_dl_layer_permutationcreate_dl_layer_permutationCreateDlLayerPermutationCreateDlLayerPermutationCreateDlLayerPermutationcreate_dl_layer_permutation 创建一个置换层,其句柄通过 DLLayerPermutationDLLayerPermutationDLLayerPermutationDLLayerPermutationDLLayerPermutationdllayer_permutation 返回。
参数 DLLayerInputDLLayerInputDLLayerInputDLLayerInputDLLayerInputdllayer_input 确定输入层,并期望层句柄作为值。
参数 LayerNameLayerNameLayerNameLayerNamelayerNamelayer_name 用于设置单个层的名称。请注意,若使用 create_dl_modelcreate_dl_modelCreateDlModelCreateDlModelCreateDlModelcreate_dl_model 创建模型,则创建网络中的每个层必须具有唯一名称。
参数 PermutationPermutationPermutationPermutationpermutationpermutation 决定了
DLLayerInputDLLayerInputDLLayerInputDLLayerInputDLLayerInputdllayer_input 轴的新顺序,输入轴应按此顺序重新排列。
PermutationPermutationPermutationPermutationpermutationpermutation 的格式为
[index width, index height, index depth,
index batch],其中索引对应输入的维度。例如,[0, 1, 3, 2] 将导致深度轴与批次轴互换。因此每个索引必须唯一且取自集合 '{0, 1, 2, 3}'"{0, 1, 2, 3}""{0, 1, 2, 3}""{0, 1, 2, 3}""{0, 1, 2, 3}""{0, 1, 2, 3}"。
使用 CPU 设备时,某些 PermutationPermutationPermutationPermutationpermutationpermutation 值会导致内部代码无法优化,从而增加运行时间。此时,层参数 'fall_back_to_baseline'"fall_back_to_baseline""fall_back_to_baseline""fall_back_to_baseline""fall_back_to_baseline""fall_back_to_baseline" 将被设置为
'true'"true""true""true""true""true"。
支持以下泛型参数 GenParamNameGenParamNameGenParamNameGenParamNamegenParamNamegen_param_name 及其对应值 GenParamValueGenParamValueGenParamValueGenParamValuegenParamValuegen_param_value:
- 'is_inference_output'"is_inference_output""is_inference_output""is_inference_output""is_inference_output""is_inference_output":
