# Quantization options

The quantization options are:

- `-quantization-precision`: Quantization precision: Int8 (default) or
Int16
- `-quantization-precision-bias`: Quantization precision bias: Int8
(default) or Int32
- `-quantization-schema-activations`: Quantization scheme to use for
activations: symmetric, symmetric\_with\_uint8 (default),
symmetric\_with\_power2\_scale
- `-quantization-schema-constants`: Quantization scheme for to use for
constants such as weights and bias: symmetric, symmetric\_with\_uint8
(default), symmetric\_with\_power2\_scale
- `-quantization-calibration`: Specify which quantization calibration
to use: KLMinimization, Percentile, MSE, SQNR, or KLMinimizationV2. If
not specified, default (None - MinMax calibration) is used.
- `-percentile-calibration-value`: Specify the value to be used with
the percentile calibration method. The specified float value must be
within 90 and 100. Default is 100.
- `-num-histogram-bins`: Sets the number of histogram bins that will
be used in profiling every node. Default is 512.
- `-convert-to-fp16`: Run all floating-point computation in fp16
(disabled by default). No quantization is performed.
- `-no-quant`: Disables quantization.
- `-node-precision-info`: Load node precision config file to run
specific instances in FP16.
- `-execute-nodes-in-fp16`: Run all instances of the operators in this
list with FP16.
- `-keep-original-precision-for-nodes`: Run all instances of the
operators in this list with original precision.
- `-external-quantization`: Provide the external quantization file
path.
- `-custom-IO-list-file`: Custom I/O configuration file.
- `-load-pre-gen-files`: Pregenerated input data files and PGQ
profiles for a batch size can be provided through this option. This is
an extension for `-input-list-file`, which is for one batch size
alone. File paths should be absolute paths or relative paths to parent
directory of the .json file.

    For an example specification, see:

    `/opt/qti-aic/scripts/qaic-model-configurator/SampleFiles/pre_gen_files.json`.
- `-enable-rowwise`: Enable row-wise quantization.
- `-enable-channelwise`: Enable channel-wise quantization.
