This document has instructions for running SSD-ResNet34 BFloat16 training using Intel-optimized TensorFlow.
SSD-ResNet34 training uses the COCO training dataset. Use the instructions to download and preprocess the dataset.
For accuracy testing, download the COCO validation dataset, using the instructions here.
| Script name | Description |
|---|---|
bfloat16_training_demo.sh |
Executes a demo run with a limited number of training steps to test performance. Set the number of steps using the TRAIN_STEPS environment variable (defaults to 100). |
bfloat16_training.sh |
Runs multi-instance training to convergence. Download the backbone model specified in the instructions below and pass that directory path in the BACKBONE_MODEL_DIR environment variable. |
bfloat16_training_accuracy.sh |
Runs the model in eval mode to check accuracy. Specify which checkpoint files to use with the CHECKPOINT_DIR environment variable. |
Setup your environment using the instructions below, depending on if you are using AI Kit:
| Setup using AI Kit | Setup without AI Kit |
|---|---|

To run using AI Kit you will need:

To run without AI Kit you will need:

For more information on the dependencies, see the installation instructions for object detection models at the TensorFlow Model Garden repository.
Running SSD-ResNet34 training uses code from the TensorFlow Model Garden.
Clone the repo at the commit specified below, and set the TF_MODELS_DIR
environment variable to point to that directory. Apply the TF2 patch from
the model zoo to the TensorFlow models directory.
# Clone the tensorflow/models repo at the specified commit.
# Please note that required commit for this section is different from the one used for dataset preparation.
git clone https://github.com/tensorflow/models.git tf_models
cd tf_models
export TF_MODELS_DIR=$(pwd)
git checkout 8110bb64ca63c48d0caee9d565e5b4274db2220a
# Apply the patch from the model zoo directory to the TensorFlow Models repo

To run the bfloat16_training_demo.sh quickstart
script, set the OUTPUT_DIR (location where you want log and checkpoint files to be written)
and DATASET_DIR (path to the COCO training dataset). Use an empty output
directory to prevent conflicts with checkpoint files from previous runs. You can optionally
set the TRAIN_STEPS (defaults to 100) and MPI_NUM_PROCESSES (defaults to 1).
# cd to your model zoo directory
cd models
export TF_MODELS_DIR=<path to the clone of the TensorFlow models repo>
export DATASET_DIR=<path to the COCO training data>
export OUTPUT_DIR=<directory where the log and checkpoint files will be written>
export TRAIN_STEPS=<optional, defaults to 100>
export MPI_NUM_PROCESSES=<optional, defaults to 1>
./quickstart/object_detection/tensorflow/ssd-resnet34/training/cpu/bfloat16/bfloat16_training_demo.sh
To run training and achieve convergence, download the backbone model using the
commands below and set your download directory path as the BACKBONE_MODEL_DIR.
Again, the DATASET_DIR should point to the COCO training dataset and the
OUTPUT_DIR is the location where log and checkpoint files will be written.
Use an empty OUTPUT_DIR to prevent conflicts with previously generated checkpoint
files. You can optionally set the MPI_NUM_PROCESSES (defaults to 4).
export BACKBONE_MODEL_DIR="$(pwd)/backbone_model"

./quickstart/object_detection/tensorflow/ssd-resnet34/training/cpu/bfloat16/bfloat16_training.sh
To run in eval mode (to check accuracy), set the CHECKPOINT_DIR to the
directory where your checkpoint files are located, set the DATASET_DIR to
the COCO validation dataset location, and the OUTPUT_DIR to the location
where log files will be written. You can optionally set the MPI_NUM_PROCESSES
(defaults to 1).
