Inputs CPU Raw Data

Description

Runs a full training step on the model with raw input data from the CPU. This includes the forward and backward pass, followed by the optimizer update and gradient reset (only if the weights are updated). The output buffer is allocated automatically.

Input parameters

 

Β Training inΒ :Β object,Β training session.

Inputs Info : cluster

inputs_data : array, contains the raw byte representation of the input tensor data, stored as a 1D flattened buffer.
inputs_shapes : array, 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.
inputs string length : array, used when the tensor type is string. If the tensor has shape [5,3], this field contains 15 values, each representing the length of a corresponding string element. This ensures that the actual size of inputs_data is known despite variable string lengths.
inputs_ranks : array, indicates the rank of the tensor, i.e. the number of dimensions (Scalar = 0, 1D = 1, 2D = 2, etc.).
inputs_types : array, defines the ONNX tensor type as an enumerated value (e.g. FLOAT, INT64, STRING).
update? : boolean, indicating whether to update the model weights at this step. If set to false, gradients are only accumulated without updating the weights.

losses_names : array, specifies which loss the data correspond to.
