Description

Finds all quantizable layers in a graph, creates a quantization configuration file, and writes the quantization configuration of the quantizable layers to the configuration file.

Restrictions

None

Prototype

create_quant_retrain_config(config_file, model_file, weights_file, config_defination=None)

Parameters

Parameter	Input/Output	Description
config_file	Input	Path (including the file name) of the QAT configuration file. The existing file (if any) in the path will be overwritten upon this API call. A string.
model_file	Input	Definition file (.prototxt) of the original Caffe model. A string.
weights_file	Input	Weight file (.caffemodel) of the original Caffe model. A string.
config_defination	Input	Simplified configuration file quant.cfg generated based on the retrain_config_caffe.proto file. The .proto file is stored in /amct_caffe/proto/* under the AMCT installation directory. For details about the parameters in the .proto file and the generated simplified quantization configuration file quant.cfg, see Simplified QAT Configuration File. Default: None* A string. Restrictions: If None, a QAT configuration file is generated based on the remaining arguments. In other cases, a configuration file in JSON format is generated based on this argument.

Returns

None

Example

from amct_caffe import amct
retrain_simple = 'retrain/retrain.cfg'
model_file = 'resnet50_train.prototxt'
weights_file = 'ResNet-50-model.caffemodel'
config_json_file = './config.json'
amct.create_quant_retrain_config(config_json_file, model_file, weights_file, retrain_simple)

Flush file:

A QAT configuration file in JSON format. (When QAT is performed again, the configuration file output by the API will be overwritten.) The following is an example. For details about the parameters, see Quantization Configuration File.
