Need TFLite Micro version compatible with TensorFlow Lite 2.12

Hi everyone,
For my university project I need a version of TensorFlow Lite Micro that is fully compatible with TensorFlow Lite 2.12.
From what I’ve seen, the Micro codebase has moved to a separate Git repository, and I can’t find the matching version there for 2.12.
Has anyone encountered this or knows how to get a TFLite Micro version that aligns exactly with TFLite 2.12?

Thanks in advance!

Hi, @user2274
Welcome to the community! I apologize for the delay in my response, TensorFlow Lite Micro was moved to its standalone repository (tensorflow/tflite-micro ) on June 25, 2021 , while TensorFlow 2.12.0 was released much later on March 23, 2023 . This means TF 2.12.0 does not contain TFLM code in its repository - it was already migrated by that time. [Ref]
Since there’s no official version mapping, you’ll need to find a compatible TFLM commit from around the TF 2.12.0 timeframe:

# Clone the standalone TFLM repository
git clone https://github.com/tensorflow/tflite-micro.git
cd tflite-micro

# Look for commits around TF 2.12.0 release (March 2023)
git log --oneline --since="2023-02-01" --until="2023-05-01"

# Choose a commit from March-April 2023 timeframe
git checkout <commit_hash_from_march_2023>

If strict version alignment is critical for your project, consider using an earlier TensorFlow version that still contained TFLM

# Use TensorFlow 2.11 or earlier (before June 2021 migration)
git clone https://github.com/tensorflow/tensorflow.git
cd tensorflow
git checkout v2.11.0  # This will contain tensorflow/lite/micro/

Whichever approach you choose test the compatibility:

  1. Model Conversion: Ensure your models convert properly with TF 2.12.0
  2. API Compatibility: Verify the TFLM APIs match your code requirements
  3. Build System: Test that the TFLM code builds with your target platform
