tf_example4 example

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

1. Download the FP32 model

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

2. Run quantizaiton 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', shape=(100, 100, 100, 3), label=True)
   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()

• Run quantization and evaluation:

    python test.py
