Extracts data from GXF Receivers.

This version of get_data_per_model uses the legacy CudaStreamHandler utility. Use the variant without a cuda_stream_handler argument to use the built-in CudaObjectHandler instead.

Returns: GXF result code

Parameters

op_input

InputContext &

Input context

in_tensors

const std::vector<std::string> &

Input tensor names

data_per_input_tensor

HoloInfer::DataMap &

Map is updated with output tensor name as key mapped to data buffer

dims_per_tensor

std::map<std::string, std::vector<int>> &

Map is updated with tensor name as key mapped to dimension of input tensor

cuda_buffer_out

bool

Flag defining the location of output memory (Device or Host)

module

const std::string &

Module that called for data extraction

context

gxf_context_t &

GXF execution context

cuda_stream_handler

CudaStreamHandler &

Cuda stream handler
