描述

set_dl_model_paramset_dl_model_paramSetDlModelParamSetDlModelParamSetDlModelParamset_dl_model_param sets the parameters and hyperparameters GenParamNameGenParamNameGenParamNameGenParamNamegenParamNamegen_param_name of the deep learning model DLModelHandleDLModelHandleDLModelHandleDLModelHandleDLModelHandledlmodel_handle to the values GenParamValueGenParamValueGenParamValueGenParamValuegenParamValuegen_param_value.

The values GenParamNameGenParamNameGenParamNameGenParamNamegenParamNamegen_param_name can attain, depend on the model type: There are parameters which can be set for any deep learning model while others can only be set for specific model types. A description of the parameters whose value you can only set but not retrieve is given below. For all other parameters the specific description is given in get_dl_model_paramget_dl_model_paramGetDlModelParamGetDlModelParamGetDlModelParamget_dl_model_param. In get_dl_model_paramget_dl_model_paramGetDlModelParamGetDlModelParamGetDlModelParamget_dl_model_param we also give an overview, for which type of model and using which operator a parameter can be set.

In the following we list the parameters GenParamNameGenParamNameGenParamNameGenParamNamegenParamNamegen_param_name you can set using this operator, set_dl_model_paramset_dl_model_paramSetDlModelParamSetDlModelParamSetDlModelParamset_dl_model_param. Thereby, the following symbols denote the model type for which the parameter can be set and has a possible influence:

Calling this option sets the momentum of all batch normalization layers within the network. The settable values are the same as described in create_dl_layer_batch_normalizationcreate_dl_layer_batch_normalizationCreateDlLayerBatchNormalizationCreateDlLayerBatchNormalizationCreateDlLayerBatchNormalizationcreate_dl_layer_batch_normalization for the parameter MomentumMomentumMomentumMomentummomentummomentum.

Note, if the network has no such layer, nothing is done and therewith the operation is regarded as successful.

Calling this option converts certain pooling layers within the network. More precisely, every non-global pooling layer with a resulting feature map of size 1x1 is converted into a global pooling layer. This means, a pooling layer performing e.g., average pooling is converted into one performing global average pooling. For more information about pooling layer and possible modes of operation, see the “Solution Guide on Classification”.

Note, if this operation is performed, it can not be undone. Accordingly, you can only call it with the value 'true'"true""true""true""true""true". Also, if the network has no such layer, nothing is done and therewith the operation is regarded as successful.

Calling this option, fuses layer pairs consisting of a batch normalization layer without activation and a directly connected activation layer with ReLU activation. In order to so do, the output of the batch normalization layer is only used as input for the activation layer. As a result a batch normalization layer with activation mode ReLU is obtained. For more information about layers and possible modes of operation, see the “Solution Guide on Classification”.

Note, if this operation is performed, it can not be undone. Accordingly, you can only call it with the value 'true'"true""true""true""true""true". Also, if the network has no such fusible layers, nothing is done and therewith the operation is regarded as successful.

Restriction: Leaky ReLU layers cannot be fused with batch normalization layers.

Calling this option, fuses layer pairs consisting of a convolution layer without activation and a directly connected activation layer with ReLU activation. In order to so do, the output of the convolution layer is only used as input for the activation layer. As a result a convolution layer with activation mode ReLU is obtained. For more information about layers and possible modes of operation, see the “Solution Guide on Classification”.

If called with 'immediately'"immediately""immediately""immediately""immediately""immediately", the GPU memory is initialized and the corresponding handle created. Otherwise this is done on demand, which may result in significantly larger execution times for the first call of apply_dl_modelapply_dl_modelApplyDlModelApplyDlModelApplyDlModelapply_dl_model or train_dl_model_batchtrain_dl_model_batchTrainDlModelBatchTrainDlModelBatchTrainDlModelBatchtrain_dl_model_batch.

If the network architecture is changed subsequently, the GPU memory is reinitialized. This can happen e.g., for changes of 'batch_size'"batch_size""batch_size""batch_size""batch_size""batch_size", 'image_dimensions'"image_dimensions""image_dimensions""image_dimensions""image_dimensions""image_dimensions" or 'input_dimensions'"input_dimensions""input_dimensions""input_dimensions""input_dimensions""input_dimensions" with subsequent calls of set_dl_model_paramset_dl_model_paramSetDlModelParamSetDlModelParamSetDlModelParamset_dl_model_param.

Note, this parameter has no effect if:

• Running on CPUs, thus if 'runtime'"runtime""runtime""runtime""runtime""runtime" is set to 'cpu'"cpu""cpu""cpu""cpu""cpu".

• Running with an AI ²-interface.

• The device has been set before using 'device'"device""device""device""device""device".

This parameter returns the HALCON-specific model type.

Models of 'generic'"generic""generic""generic""generic""generic" fulfill all model functions. But several deep learning procedures rely a specific 'type'"type""type""type""type""type". The value of 'type'"type""type""type""type""type" can be set from 'generic'"generic""generic""generic""generic""generic" to the following values:

• 'classification'"classification""classification""classification""classification""classification"

• 'segmentation'"segmentation""segmentation""segmentation""segmentation""segmentation"

Setting a value for 'type'"type""type""type""type""type" to model it is checked if it has all layers necessary for inference and training. In case such layers are missing, they are added.
