3D Data to Loss Input Array by index

Description

This VI adds a new input entry (of type BOOL, SGL, INT, UINT, or STRING) to an existing array of loss input data clusters. It is used to progressively build a structured list of model loss inputs. Once constructed, the full array of loss input clusters can be passed to Training Multi-Input Execution VIs, which perform training using all specified loss inputs in a single execution step. Type : polymorphic.

 

 

Input parameters

 

Β 3D Input Data : array,Β 3D array of data with any type : integers (signed/unsigned), floats, doubles, booleans, or strings.

Data in : array,Β is an array of clusters, where each cluster represents a single model input. Each cluster contains metadata and raw data required to describe and pass an input tensor to the model.

Β y_true_order :Β integer,Β defines the position of the input within the data array. It corresponds to the index assigned to the input when it is created (via theΒ indexΒ parameter).
Β Inputs Info :Β cluster

Β inputs_data :Β array,Β contains the raw byte representation of the input tensor data, stored as a 1D flattened buffer.
Β inputs_shapes :Β array,Β specifies the shape of the input tensor. Since the data is stored as a flattened 1D buffer, this shape is necessary to reconstruct the original dimensions.
Β inputs string length :Β array,Β used when the tensor type is string. If the tensor has shapeΒ [5,3], this field contains 15 values, each representing the length of a corresponding string element. This ensures that the actual size ofΒ inputs_dataΒ is known despite variable string lengths.
Β inputs_ranks :Β array,Β indicates the rank of the tensor, i.e. the number of dimensions (Scalar = 0, 1D = 1, 2D = 2, etc.).
Β inputs_types :Β array,Β defines the ONNX tensor type as an enumerated value (e.g. FLOAT, INT64, STRING).

​

Β input order : integer,Β defines the position of the input within the data array. It corresponds to the index assigned to the input when it is created (via theΒ indexΒ parameter).

 

Output parameters

 

Β Data out : array,Β is an array of clusters, where each cluster represents a single model input. Each cluster contains metadata and raw data required to describe and pass an input tensor to the model.

Β y_true_order :Β integer,Β defines the position of the input within the data array. It corresponds to the index assigned to the input when it is created (via theΒ indexΒ parameter).
Β Inputs Info :Β cluster

Β inputs_data : array,Β contains the raw byte representation of the input tensor data, stored as a 1D flattened buffer.
Β inputs_shapes :Β array,Β specifies the shape of the input tensor. Since the data is stored as a flattened 1D buffer, this shape is necessary to reconstruct the original dimensions.
Β inputs string length :Β array,Β used when the tensor type is string. If the tensor has shapeΒ [5,3], this field contains 15 values, each representing the length of a corresponding string element. This ensures that the actual size ofΒ inputs_dataΒ is known despite variable string lengths.
Β inputs_ranks :Β array,Β indicates the rank of the tensor, i.e. the number of dimensions (Scalar = 0, 1D = 1, 2D = 2, etc.).
Β inputs_types :Β array,Β defines the ONNX tensor type as an enumerated value (e.g. FLOAT, INT64, STRING).
