Included prebuilt libraries

• All libraries except iOS are targeted 64bit platform: arm64 or x86_64.

• Clone this repository with examples
  • Need Git-LFS to build for iOS
• The TFLite core library is available on:
  • OpenUPM
    Run openupm add com.github.asus4.tflite from the command line.
  • Or add git URL from the Package Maneger UI: https://github.com/asus4/tf-lite-unity-sample.git?path=/Packages/com.github.asus4.tflite

Pre-built libraries are included. If you want to build the latest TFLite,

1. Clone TensorFlow library
2. Run ./configure in the TensorFlow library
3. Run ./build_tflite.py (Python3) to build for each platform

# Update iOS, Andoid and macOS
./build_tflte.py --tfpath ../tensorflow -ios -android -macos

# Build with XNNPACK
./build_tflte.py --tfpath ../tensorflow -macos -xnnpack

• To build macOS Metal Delegate on TensorFlow v2.3.0 or later, You need to apply following changes the issue

[Android] You can see logs from tflite by filtering with "tflite"

# Filtering logcat only Unity and tflite
adb logcat Unity:V tflite:V "*:S"
