QATModule

class QATModule(**kwargs)[source]

Base class of quantized-float related Module, basically for QAT and Calibration.

Use from_float_module to generate a instance from float Module. Or use quantize_qat to do it recursively and automatically.

Can also be converted to QuantizedModule for deployment using quantize further.

apply_quant_activation(target)[source]

Apply weight’s observer and fake_quant from qconfig on target.

apply_quant_bias(target, inp, w_qat)[source]

Use fake_quant_bias to process target. Only valid when act_fake_quant and weight_fake_quant are both enabled.

apply_quant_weight(target)[source]

Apply weight’s observer and fake_quant from qconfig on target.

abstract classmethod from_float_module(float_module)[source]

Return a QATModule instance converted from a float Module instance.

get_activation_dtype()[source]

Get activation’s quantization dtype as the method from qconfig.

get_activation_qparams()[source]

Get activation’s quantization parameters.

get_weight_dtype()[source]

Get weight’s quantization dtype as the method from qconfig.

get_weight_qparams()[source]

Get weight’s quantization parameters.

set_qconfig(qconfig)[source]

Set quantization related configs with qconfig, including observer and fake_quant for weight and activation.
