CNumericIO

Float specialization of C++ template class CNumericIO.

class ikomia.dataprocess.pydataprocess.CNumericIO

Define input or output for a task consuming or producing data as numeric values. C++ implementation uses template to handle various data types. In Python, Ikomia API exposes only the double precision (float) and string specializations. The class is designed to handle row/column data structure, it consists on a list of values, a list of associated labels and a display type (see NumericOutputType). For the specific case of plot display, a plot type property is available (see PlotType). Derived from CWorkflowTaskIO
