Python Wheel generation of TensorFlow Lite 2.17 for ARMv7l 32 bits not working #37

Open gaikwadrahul8 opened 5 days ago

gaikwadrahul8 commented 5 days ago

I have previously crosscompiled different versions of TensorFlow lite (2.14, 2.15.1, 2.16.2) for Python 3.10 using CMAKE and following the instructions from the website .

So far the only changes required were to just set my armhf flags as:

echo "ARMCC_FLAGS=\"-march=armv7-a -mfpu=neon-vfpv3 -funsafe-math-optimizations \ adjust the python version in the MakeFile (tensorflow/lite/tools/pip_package/Makefile) and run the make command as:

make -C tensorflow/lite/tools/pip_package docker-build \ TENSORFLOW_TARGET=armhf PYTHON_VERSION=3.10 Now, I have tried the same approach for the release 2.17.0 ( ad6d8cc ) and although the build is executed and the wheel is generated without errors, I keep getting the following errorat the moment of importing the interpreter:

python3 simpletest.py 
Traceback (most recent call last):
  File "/mnt/simpletest.py", line 2, in <module>
    import tflite_runtime.interpreter as tflite
  File "/usr/local/lib/python3.10/dist-packages/tflite_runtime/interpreter.py", line 33, in <module>
    from tflite_runtime import _pywrap_tensorflow_interpreter_wrapper as _interpreter_wrapper
ImportError: /usr/local/lib/python3.10/dist-packages/tflite_runtime/_pywrap_tensorflow_interpreter_wrapper.so: undefined symbol: TfLiteXNNPackDelegateOptionsDefault
