When I call the tflite file on the Raspberry Pi 3B+, the following error occurred. here is the code:

tflite_path='home/pi/project/model_pb.tflite'
interpreter = tflite.Interpreter(model_path=tflite_path)
interpreter.allocate_tensors()   
input_details = interpreter.get_input_details()
output_details = interpreter.get_output_details()
interpreter.set_tensor(input_details[0]['index'],img_values)
interpreter.invoke()
output_data = interpreter.get_tensor(output_details[0]['index'])

And the error:

Traceback (most recent call last):

I have changed tensorflow version，but it did not work,my python is 3.7.3 and the tensorflow is 1.13.1,it worked well in windows.what's wrong?

  • _tensorflow_wrap_interpreter_wrapper.so depends on a function of another library, not found in your path. https://github.com/tensorflow/tflite-support – Soleil Dec 29 '20 at 04:33
