Question

我正在尝试在Android上运行我的Tensorflow模型，因此我使用nightly native build in here并在Android demo之后，我已成功运行Tensorflow Android lib并在下面加载模型代码。

inferenceInterface = new TensorFlowInferenceInterface(getAssets(), MODEL_FILE);

日志显示结果很好。

I/TensorFlowInferenceInterface: Successfully loaded TensorFlow native methods (RunStats error may be ignored)
I/TensorFlowInferenceInterface: Model load took 1007ms, TensorFlow version: 1.2.0-rc0
I/TensorFlowInferenceInterface: Successfully loaded model from 'file:///android_asset/model.pb'

然而，当我完成所有输入节点的输入

inferenceInterface.feed("input1", new int[]{1, 2, 3}, 1, 3);
inferenceInterface.feed("input2", new int[]{3}, 1);
inferenceInterface.feed("input3", new int[]{4}, 1);

然后调用run方法

inferenceInterface.run(new String[]{"output"});

Tensorflow被打破，说某些内核未注册

我认为int32的“LessEqual”应该在Tensorflow中定义，但不是与Tensorflow Android Lib一起构建的。

所以我的问题是如何在Android lib版本中包含更多内核或以其他任何方式解决此问题，我们将非常感谢任何帮助。

我建议阅读这本免费的电子书：Building Mobile Applications with TensorFlow

它有一个关于What Ops Are Available on Mobile?（第33页）的部分，它解释了如何Add the implementation to the build那些默认为移动构建被剥离的操作内核。

仅供参考，该电子书由Pete Warden（GitHub，blog）撰写，他在Google工作，是TensorFlow的维护者之一。
