Description

The operator set_dl_model_layer_weightsset_dl_model_layer_weightsSetDlModelLayerWeightsSetDlModelLayerWeightsset_dl_model_layer_weights sets for the model DLModelHandleDLModelHandleDLModelHandleDLModelHandledlmodel_handle the given WeightsWeightsWeightsweightsweights in the specified LayerNameLayerNameLayerNamelayerNamelayer_name.

The parameter WeightsTypeWeightsTypeWeightsTypeweightsTypeweights_type determines which type of layer values are set. Which values can be set, please refer to the get_dl_model_layer_weightsget_dl_model_layer_weightsGetDlModelLayerWeightsGetDlModelLayerWeightsget_dl_model_layer_weights documentation.

Attention

The operator set_dl_model_layer_weightsset_dl_model_layer_weightsSetDlModelLayerWeightsSetDlModelLayerWeightsset_dl_model_layer_weights is only applicable to self-created networks. For networks delivered by HALCON, the operator does have no impact.

Execution Information

  • Multithreading type: reentrant (runs in parallel with non-exclusive operators).
  • Multithreading scope: global (may be called from any thread).
  • Processed without parallelization.

Example (HDevelop)

* Create weights for a convolution layer.
gen_image_const (Weights, 'real', 1, 1)
paint_region (Weights, Weights, Weights, 1, 'fill')
gen_empty_obj (WeightsArray)
for Index := 0 to 10 by 1
    concat_obj (WeightsArray, Weights, WeightsArray)
endfor
*
* Input image with rows consisting of 1s to 10s.
gen_image_const (Image, 'real', 10, 10)
for Index := 0 to 9 by 1
    gen_rectangle1 (Rectangle, Index, 0, Index, 9)
    paint_region (Rectangle, Image, Image, Index + 1, 'fill')
endfor
*
* Create a small model network.
create_dl_layer_input ('image', [10, 2, 1], [], [], ImageNode)
create_dl_layer_convolution (ImageNode, 'conv', 1, 1, 2, 11, 1, 'none', \
                             'none', [], [], ConvNode)
create_dl_layer_zoom_factor (ConvNode, 'zoom', 2, 2, 'bilinear', 'true', [],\
                             [], ZoomNode)
create_dl_model (ZoomNode, DLModelHandle)
set_dl_model_param (DLModelHandle, 'runtime', 'cpu')
*
* Set the weights to the convolution layer.
set_dl_model_layer_weights (WeightsArray, DLModelHandle, 'conv', 'weights')
