python - Raspberry Pi 3B+ 上的 Tensorflow Lite Python 绑定

问题描述

我正在尝试使用Tensorflow Lite Python 解释器在树莓派 3B+ 中进行对象检测，就像这样

from tensorflow.contrib.lite.python import interpreter as interpreter_wrapper

但是当我运行这条线时interpreter=interpreter_wrapper.Interpreter(model_path="mobilenet.tflite")

我收到此错误：

Traceback (most recent call last):

如果有人试过这个，请帮我解决这个错误

谢谢

解决方案

我找到了一个答案页面。 https://github.com/tensorflow/tensorflow/issues/21574 我认为，你最好从源代码构建一个 Python 包（Docker Cross 在 unbunt 或 centos 上编译等）。 https://www.tensorflow.org/install/install_raspbian -> 从源代码交叉编译
