我为什么会出现错误：初始化Tensorflow？

概述我正在尝试通过本教程构建.apk文件-https://www.oreilly.com/learningensorflow-on-android我想使用自己的retrained_graph.pb我更改了ClassifierActivity.java(在教程中为TensorFlowImageListener.java,但我没有找到该文件).我更换：privatestaticfinalintINPUT_SIZE=2

我正在尝试通过本教程构建.apk文件-https://www.oreilly.com/learning/tensorflow-on-android

我想使用自己的retrained_graph.pb

我更改了ClassifIErActivity.java(在教程中为TensorFlowImageListener.java,但我没有找到该文件).
我更换：

private static final int input_SIZE = 299;private static final int IMAGE_MEAN = 128;private static final float IMAGE_STD = 128;private static final String input_name = "Mul:0";private static final String OUTPUT_name = "final_result:0";private static final String MODEL_file = "file:///androID_asset/retrained_graph.pb";private static final String LABEL_file = "file:///androID_asset/retrained_labels.txt";

但是,当我在设备上运行apk时-初始化TensorFlow出错时崩溃.

我发现这段代码可以处理异常：

private static final String input_name = "Mul:0";private static final String OUTPUT_name = "final_result:0";

在tensorflow / tensorflow / examples / androID / src / org / tensorflow / demo / ClassifIErActivity.java中

我已经呆了2天,请大家帮帮我！错误的原因是什么？

解决方法:

我解决了这个问题,java代码中的注释未更新,现在只需更改即可：

private static final String input_name = "Mul";private static final String OUTPUT_name = "final_result";

至：
