DescriptorSetDataCSV

DescriptorSetDataCSV Objects

class DescriptorSetDataCSV(CSVParser.CSVParser)

ApertureDB DescriptorSet Data.

This class loads the Descriptor Set Data which is present in a CSV file, and converts it into a series of aperturedb queries.

Is backed by a CSV file with the following columns:

name, dimensions, engine, metric, PROP_NAME_N, constraint_PROP1

Example CSV file::

name,dimensions,engine,metric
dining_chairs,2048,FaissIVFFlat,L2
chandeliers,2048,FaissIVFFlat,L2
console_tables,2048,FaissIVFFlat,L2
...

Example code to create an instance:

    data = DescriptorSetDataCSV("/path/to/DescriptorSetData.csv")
    loader = ParallelLoader(db)
    loader.ingest(data)

info

In the above example, the first row implies to create a Descriptor set called dining_chairs. The Descriptors in that set would be expected to be an array of float64, of length 2048. When performing a search on this set, FaissIVFFlat engine would be used and the metric to compute the distance would be L2.
