Tiler

class model_api.tilers.tiler.Tiler(model, configuration={}, execution_mode='async')

Bases: ABC

Base constructor for creating a tiling pipeline

Parameters:

• model – underlying model

• configuration (dict) – it contains values for parameters accepted by specific tiler (tile_size, tiles_overlap etc.) which are set as data attributes.

• execution_mode (str) – Controls inference mode of the tiler (async or sync).

__call__(inputs)

Applies full pipeline of tiling inference in one call.

Parameters:

inputs – raw input data, the data type is defined by underlying model wrapper

Returns:

• postprocessed data in the format defined by underlying model wrapper

get_model()

Getter for underlying model

classmethod parameters()

Defines the description and type of configurable data parameters for the tiler.

The structure is similar to model wrapper parameters.

Returns:

• the dictionary with defined wrapper tiler parameters

EXECUTION_MODES = ['async', 'sync']

An abstract tiler

The abstract tiler is free from any executor dependencies. It sets the Model instance with the provided model and applies it to tiles of the input image, and then merges results from all tiles.

The _postprocess_tile and _merge_results methods must be implemented in a specific inherited tiler. .. attribute:: logger
