Adapters

Adapter is a class for converting raw network infer output to specific representation format which is suitable for the further postprocessors work and the metrics calculation. Adapters may have parameters available for configuration. The adapter and its parameters, if necessary, are set through the configuration file.

Describing how to set adapter in Configuration File

Adapters can be provided in launchers section of configuration file for each launcher to use specific adapter.

You can use 2 ways to set adapter for topology:

• Define adapter as a string.

adapter: classification

• Define adapter as a dictionary, using type: for setting adapter name. This approach gives opportunity to set additional parameters for adapter if it is required.

adapter:
  type: reid
  grn_workaround: False
