Download Command

wget https://storage.googleapis.com/intel-optimized-tensorflow/models/v2_3_0/resnet50-int8-inference.tar.gz

Description

This document has instructions for running ResNet50* int8 inference using Intel® Optimization for TensorFlow*.

Download and preprocess the ImageNet dataset using the instructions here. After running the conversion script you should have a directory with the ImageNet dataset in the TF records format. Set the DATASET_DIR to point to this directory when running ResNet50.

Quick Start Scripts

Script name Description
int8_inference Runs batch inference (batch_size=128).
int8_accuracy Measures the model accuracy (batch_size=100).

Bare Metal

To run on bare metal, the following prerequisites must be installed in your environment:

Download and untar the model package. Set environment variables for the path to your DATASET_DIR and an OUTPUT_DIR where log files will be written, then run a quick start script.

DATASET_DIR=<path to the dataset>
OUTPUT_DIR=<directory where log files will be written>

wget https://storage.googleapis.com/intel-optimized-tensorflow/models/v2_3_0/resnet50-int8-inference.tar.gz
tar -xzf resnet50-int8-inference.tar.gz
cd resnet50-int8-inference
