How make converted to tflite work? (guide on NXP site may be outdated)

[korabelnikov]

I follow the article https://community.nxp.com/t5/Software-Community-Articles/eIQ-Sample-Apps-TFLite-Quantization/ba-p/11...

I've installed tensorflow strictly the same version as in article, and downloaded the same model.

I've got converted .tflite model, that's seems good in netron visualizer.

Then (in opposite to the article) I try run it pyEIQ. pyEIQ is checked, it worked with some tflite models.

But I get error

self.interpreter = aNNInterpreter(model_file)
File "/usr/lib/python3.7/site-packages/eiq/engines/armnn/inference.py", line 19, in __init__
network = parser.CreateNetworkFromBinaryFile(model)
File "/usr/lib/python3.7/site-packages/pyarmnn/_generated/pyarmnn_tfliteparser.py", line 711, in CreateNetworkFromBinaryFile
return _pyarmnn_tfliteparser.ITfLiteParser_CreateNetworkFromBinaryFile(self, graphFile)

I think the issue is with tensorflow version, that converts tensorflow to tflite. But there is no more info about tf version to use.

Additionally I've tried modern versions of tensorflow i.e. 2.3.0, 2.3.1 but got segfault(139)
