running coral code on Mac

[ilonadem]

Description

Hi, I'm trying to test the models deployed by the coral on my Mac for benchmarking purposes. Is it possible to install+run the pycoral library on a Mac without the USB accelerator? I've followed the installation instructions as outlined by: https://coral.ai/docs/edgetpu/tflite-python/#inferencing-example and https://coral.ai/software/#pycoral-api, but the main error I get when trying to run the inferencing example in https://coral.ai/docs/edgetpu/tflite-python/#inferencing-example I get the following error:

Traceback (most recent call last):
  File "/Users/ilonademler/miniconda3/lib/python3.8/site-packages/tflite_runtime/interpreter.py", line 160, in load_delegate
    delegate = Delegate(library, options)
  File "/Users/ilonademler/miniconda3/lib/python3.8/site-packages/tflite_runtime/interpreter.py", line 119, in __init__
    raise ValueError(capture.message)
ValueError

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/Users/ilonademler/Documents/Harvard/seniorfall/coral/test_script.py", line 18, in <module>
    experimental_delegates=[tflite.load_delegate('libedgetpu.1.dylib')])
  File "/Users/ilonademler/miniconda3/lib/python3.8/site-packages/tflite_runtime/interpreter.py", line 162, in load_delegate
    raise ValueError('Failed to load delegate from {}\n{}'.format(

What means to run it without USB accelerator? How to load runtime if there is no device to run it on? Software runs only on hardware. What is the sense to run it if there is no device connected?

Is it possible to install+run the pycoral library on a Mac without the USB accelerator?

To use pycoral API without USB accelerator for uncompiled tflite models, please change interpreter with https://github.com/hjonnala/snippets/blob/main/coral_inference.py#L27.

You won't be able to test the EdgeTPU models without the Coral Device. Thanks!!
