Raspberry Pi + Python + Tensorflow Lite特定于tflite_interpreter.invoke的错误

如何解决Raspberry Pi + Python + Tensorflow Lite特定于tflite_interpreter.invoke的错误

我开发了一个图像分类程序，现在正在多台RaspBerry Pi（约10个）上对其进行测试。通常，它工作正常，没有错误，并且令人满意。但是在RPis的2上，出现以下错误。

我猜这是因为tflite_interpreter，因为RPi的先前工作文件可以正常工作了。但是同样，在7个RPi上没有问题，只有2个出现了此类错误。

是否可以从此错误消息中了解错误的性质？

RaspBerry Pi是最便宜的产品-RaspBerry Pi 0 W。
