Tensorflow v2 benchmark

TensorFlow benchmark scripts for single and multi Nodes with Multi GPUs

Usage

Clone repo

git clone https://github.com/reger-men/tensorflow_benchmark.git

Pre-requirement

pip3 install -r requirements.txt

Single Node Single GPU

Train with custom loop:

python3 train.py -train_mode loop

Train with Keras fit:

python3 train.py -train_mode fit

Single Node Multi-GPUs

Mirrored strategy will be used as default with num_gpus>1

python3 train.py -train_mode fit -num_gpus 2

python3 train.py -train_mode loop -num_gpus 2

Multi-Node Multi-GPUs

Experimental: launch Multi-Nodes training from the chief Worker Node

python3 train.py --train_mode=fit --workers="localhost:122,localhost:123" --w_type="worker" --w_index=0 --distribution_strategy=MultiWorker

Or with custom loop:

python3 train.py --train_mode=loop --workers="localhost:122,localhost:123" --w_type="worker" --w_index=0 --distribution_strategy=MultiWorker
