Hi everyone,

I am trying to use a TensorFlow model converted to TFLite Micro on my Arduino BLE, however I got the following error.


Didn't find op for builtin opcode 'TRANSPOSE' version '2'. An older version of this builtin might be supported. Are you using an old TFLite binary with a newer model?

Failed to get registration from op code TRANSPOSE

 Failed starting model allocation.

Invoke() called after initialization failed

Invoke failed!


I have checked the arduino tensorflow lite library version, that the latest. 

I have used tensorflow-2.6.0 to train and convert my model.

My conversion code:


# Convert the model to the TensorFlow Lite format without quantization
converter = tf.lite.TFLiteConverter.from_keras_model(origin_model)

converter.target_spec.supported_ops = [
tf.lite.OpsSet.TFLITE_BUILTINS, # enable TensorFlow Lite ops.

tflite_model = converter.convert()

# Save the model to disk
open(FOLDER_DRIVE_MODEL_DL + 'tflite/' + tflite_model_name + ".tflite", "wb").write(tflite_model)


My converted model architecture:


In any case, don’t hesitate to correct me if I am wrong.

Hi, Antoine

Did you use AllOpsResolver?
If you're using your own MicroMutableOpResolver, you should register op kernels you're using.

Hi Terry,

Thanks for your quick answer.

I used the default imports in my Arduino code :

#include <TensorFlowLite.h>
#include <tensorflow/lite/micro/all_ops_resolver.h>
#include <tensorflow/lite/micro/micro_error_reporter.h>
#include <tensorflow/lite/micro/micro_interpreter.h>
#include <tensorflow/lite/schema/schema_generated.h>
#include <tensorflow/lite/version.h>
I have found this issue, which is related to my problem. Would you have any recommendation to generate my own .zip Arduino library?

Please check the example code how to create your own OpResolver.

You should have something like `micro_op_resolver.AddTranspose()`.

Or just simply use AllOpsResolver.

Can you try the latest TFLM Arduino library from this repository and let us know if you continue to run into this issue?

Cross-linking the issue that you had created on the TFLM repository for completeness: https://github.com/tensorflow/tflite-micro/issues/566

And please feel free to ask TFLM-specific questions via a github issue on the TFLM repository or the SIG-micro mailing list.
