Number of calibration batches

Number of calibration batches

Description

App Configuration Pane: Deep Learning

Configuration Objects: coder.TensorRTConfig

Numeric value specifying the number of batches for int8 calibration. The software uses the product of batchsize*NumCalibrationBatches to pick a random subset of images from the image dataset to perform calibration. The batchsize*NumCalibrationBatches value must not be greater than the number of images present in the image dataset. This option is applicable only when DataType is set to 'int8'.

NVIDIA® recommends that about 500 images are sufficient for calibrating. Refer to the TensorRT documentation for more information.

Dependencies

To enable this parameter, you must set both these parameters:

  • Deep learning library to TensorRT

  • Data type to int8

Settings
