Failed precondition: Package requires runtime version (14), which is newer than this runtime version (13). #104

Description

I have a Google Coral USB device and I am currently trying to use it on my Windows 11 machine for a custom object detection model. The model for object detection was trained following this tutorial: https://colab.research.google.com/github/khanhlvg/tflite_raspberry_pi/blob/main/object_detection/Train_custom_model_tutorial.ipynb.

During the installation guide in the Coral.Ai website, I had failed attempts to install edgetpu_runtime_20221024 version, as it starts but when clicking execute the screen closes down, I searched a bit and installed the edgetpu_runtime_20210119-1 successfully. Therefore, by the end of the tutorial I was able to run both image classification and object detection examples. However, when I use my own model trained on the tutorial above, with the following command:


py -3.9 examples/detect_image.py \
  --model test_data/custom_model_edgetpu.tflite \
  --labels test_data/Labels.txt \
  --input test_data/test_image.jpeg \
  --output test_data/test_image.jpeg

I am getting a runtime version installed, despite being able to run inference on the downloaded examples. This is the error I get when I try to run inference with my own model: RuntimeError: Failed to prepare for TPU. Failed precondition: Package requires runtime version (14), which is newer than this runtime version (13).Node number 4 (EdgeTpuDelegateForCustomOp) failed to prepare.

Please install latest runtime version and replace libusb with the older version: https://github.com/google-coral/tflite/issues/60#issuecomment-1341113519

Hi thanks for replying. I am using Windows 11 and the .bat file simply closes after I try to run it, so i am unable to install the latest version. However, the same doesn't happen to older versions

I am able to run .bat file normally without any issues on windows 11. Please try to install using powershell as admin..

Warning: During normal operation, the Edge TPU Accelerator may heat up,
depending on the computation workloads and operating frequency. Touching the
metal part of the device after it has been operating for an extended period of
time may lead to discomfort and/or skin burns. As such, when running at the
default operating frequency, the device is intended to safely operate at an
ambient temperature of 35C or less. Or when running at the maximum operating
frequency, it should be operated at an ambient temperature of 25C or less.

Google does not accept any responsibility for any loss or damage if the device
is operated outside of the recommended ambient temperature range.
