Description

This document has instructions for running ResNet34* SSD FP32 training using Intel® Optimization for TensorFlow*.

Datasets

ResNet34 SSD training uses the COCO dataset. Use the following instructions to download and preprocess the dataset.

  1. Download and extract the 2017 training images and annotations for the COCO dataset:

    export MODEL_WORK_DIR=$(pwd)
    
    # Download and extract train images
    wget http://images.cocodataset.org/zips/train2017.zip
    unzip train2017.zip
    
    # Download and extract annotations
    wget http://images.cocodataset.org/annotations/annotations_trainval2017.zip
    unzip annotations_trainval2017.zip
  2. Since we are only using the train and validation dataset in this example, we will create an empty directory and empty annotations JSON file to pass as the test directories in the next step.

    # Create an empty dir to pass for validation and test images
    mkdir empty_dir
    
    # Add an empty .json file to bypass validation/test image preprocessing
    cd annotations
    echo "{ \"images\": {}, \"categories\": {}}" > empty.json
    cd ..
  3. Use the TensorFlow models repo scripts to convert the raw images and annotations to the TF records format.

    git clone https://github.com/tensorflow/models.git tf_models
    cd tf_models
    git checkout 7a9934df2afdf95be9405b4e9f1f2480d748dc40
    cd ..
  4. Install the prerequisites mentioned in the TensorFlow models object detection installation doc and run protobuf compilation on the code that was cloned in the previous step.

  5. After your envionment is set up, run the conversion script:

    cd tf_models/research/object_detection/dataset_tools/
    
    # call script to do conversion
    python create_coco_tf_record.py --logtostderr \
          --train_image_dir="$MODEL_WORK_DIR/train2017" \
          --val_image_dir="$MODEL_WORK_DIR/empty_dir" \
          --test_image_dir="$MODEL_WORK_DIR/empty_dir" \
          --train_annotations_file="$MODEL_WORK_DIR/annotations/instances_train2017.json" \
          --val_annotations_file="$MODEL_WORK_DIR/annotations/empty.json" \
          --testdev_annotations_file="$MODEL_WORK_DIR/annotations/empty.json" \
          --output_dir="$MODEL_WORK_DIR/output"

    The coco_train.record-*-of-* files are what we will use in this training example. Set the output of the preprocessing script (export DATASET_DIR=$MODEL_WORK_DIR/output) when running quick start scripts.

Quick Start Scripts

Script name Description
fp32_training Runs 100 training steps using mpirun for the specified number of processes (defaults to MPI_NUM_PROCESSES=1).

Bare Metal

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

  • Python* 3
  • Contextlib2
  • Cpio
  • Cython
  • Horovod*
  • Intel® Optimization for Tensorflow*
  • Jupyter*
  • Lxml
  • Matplotlib
  • NumPy 1.17.4
  • OpenCV
  • Open MPI
  • OpenSSH
  • Pillow 7.1.0
  • Protoc
  • Pycocotools
  • TensorFlow add-ins 0.8.1

For more information, see the installation instructions for object detection models at the TensorFlow Model Garden repository.

After installing the prerequisites, download and untar the model package. Clone the TensorFlow Model Garden repo at the commit specified below, and set the TF_MODELS_DIR environment variable to point to that directory. Set the DATASET_DIR to point to the directory with COCO training TF records files and the OUTPUT_DIR to the location where logs will be written. You can optionally set the MPI_NUM_PROCESSES environment variable (defaults to 1). After all the setup is complete, run the quick start script.

export DATASET_DIR=<path to the dataset>
export OUTPUT_DIR=<directory where log files will be written>
export MPI_NUM_PROCESSES=<number of MPI processes (optional, defaults to 1)>

# Clone the tensorflow/models repo at the specified commit
git clone https://github.com/tensorflow/models.git tf_models
cd tf_models
export TF_MODELS_DIR=$(pwd)
git checkout 8110bb64ca63c48d0caee9d565e5b4274db2220a
cd ..

# Download and extract the model package, then run a quickstart script
wget https://storage.googleapis.com/intel-optimized-tensorflow/models/v2_3_0/ssd-resnet34-fp32-training.tar.gz
tar -xzf ssd-resnet34-fp32-training.tar.gz
cd ssd-resnet34-fp32-training
