tf_example4 example

This example is used to demonstrate how to quantize a TensorFlow checkpoint and run with a dummy dataloader.

1. Installation

pip install -r requirements.txt

2. Download the FP32 model

git clone https://github.com/openvinotoolkit/open_model_zoo.git
git checkout 2021.4
python ./open_model_zoo/tools/downloader/downloader.py --name rfcn-resnet101-coco-tf --output_dir model 

3. Run Command

python test.py

4. Introduction

We will create a dummy dataloader and only need to add the following lines for quantization to create an int8 model.

    quantizer = Quantization('./conf.yaml')
    dataset = quantizer.dataset('dummy_v2', \
        input_shape=(100, 100, 3), label_shape=(1, ))
    quantizer.model = common.Model('./model/public/rfcn-resnet101-coco-tf/rfcn_resnet101_coco_2018_01_28/')
    quantizer.calib_dataloader = common.DataLoader(dataset)
    quantized_model = quantizer.fit()
