珊瑚 USB 示例模型在 Ubuntu 上失败

如何解决珊瑚 USB 示例模型在 Ubuntu 上失败

我正在尝试在 VirtualBox 上的 Ubuntu 客户机上的 Coral USB 加速器上运行示例模型。我按照说明运行示例模型。一切都很顺利，直到我运行实际模型，它以下列方式失败。

VirtualBox:~/coral/pycoral$ python3 examples/classify_image.py --model test_data/mobilenet_v2_1.0_224_inat_bird_quant_edgetpu.tflite --labels test_data/inat_bird_labels.txt --input test_data/parrot.jpg
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/tflite_runtime/interpreter.py",line 152,in load_delegate
    delegate = Delegate(library,options)
  File "/usr/lib/python3/dist-packages/tflite_runtime/interpreter.py",line 111,in __init__
    raise ValueError(capture.message)
ValueError

During handling of the above exception,another exception occurred:

Traceback (most recent call last):
  File "examples/classify_image.py",line 84,in <module>
    main()
  File "examples/classify_image.py",line 61,in main
    interpreter = make_interpreter(*args.model.split('@'))
  File "/usr/lib/python3/dist-packages/pycoral/utils/edgetpu.py",line 66,in make_interpreter
    delegates = [load_edgetpu_delegate({'device': device} if device else {})]
  File "/usr/lib/python3/dist-packages/pycoral/utils/edgetpu.py",line 42,in load_edgetpu_delegate
    return tflite.load_delegate(_EDGETPU_SHARED_LIB,options or {})
  File "/usr/lib/python3/dist-packages/tflite_runtime/interpreter.py",line 154,in load_delegate
    raise ValueError('Failed to load delegate from {}\n{}'.format(
ValueError: Failed to load delegate from libedgetpu.so.1

VirtualBox:~/coral/pycoral$ dpkg -l |grep libedge
ii  libedgetpu1-std:amd64                      15.0                                amd64        Support library for Edge TPU

任何帮助将不胜感激。谢谢！

解决方法

拔下并重新插入 Coral USB 适配器。它为我解决了同样的问题。
