Run TensorFlow model on GraalVM

Overview

GraalVM is an alternative to HotSpot JVM that allows you to compile the application code ahead of time (AOT) into a native execute.

This is an example to demonstrate how to use Deep Java Library to run a TensorFlow model on GraalVM.

Setup

Follows the GraalVM installation instruction to set up GraalVM on your system. Make sure the native-image tool also gets installed:

  • Configure $GRAALVM_HOME and $JAVA_HOME environment variable to the location you installed

    # for example:
export $GRAALVM_HOME=/path/to/graalvm/
export $JAVA_HOME=$GRAALVM_HOME

  • native-image is installed

    $GRAAL_HOME/bin/gu install native-image

Build and run the application

Run the following command to build the project and run:

# set environment variable to suppress TensorFlow logging:
export TF_CPP_MIN_LOG_LEVEL=1

./mvnw clean
./mvnw package exec:java

[
	class: "n04254680 soccer ball", probability: 0.92693
	class: "n04039381 racket, racquet", probability: 0.06132
	class: "n09835506 ballplayer, baseball player", probability: 0.01018
	class: "n04540053 volleyball", probability: 0.00068
	class: "n02799071 baseball", probability: 0.00026
]

Build native image

Run the following command to build the native executable for this project:

# build native iamge with TensorFlow engine
./mvnw clean package -Pnative -Ptensorflow

# build native iamge with PyTorch engine
./mvnw clean package -Pnative -Ppytorch

You will find a native executable file generated: target/image-classification

Run application

# set environment variable to suppress TensorFlow logging:
export TF_CPP_MIN_LOG_LEVEL=1
target/image-classification
