Tensorflow：无法在 gradle 中解析

今天早上我打开 Android Studio 时，Gradle 尝试同步时出现以下错误：

Error:(103, 13) Failed to resolve: org.tensorflow:tensorflow-android:+

按照他们的说明Github 自述文件 https://github.com/tensorflow/tensorflow/tree/master/tensorflow/contrib/android，他们使用动态版本（Android Studio 警告我这一点）。前一天它还在工作。

我确实尝试使用他们拥有的唯一显式版本：1.3.0，但这在尝试使用示例代码加载语音识别模型时会导致另一个问题：

java.lang.RuntimeException: Failed to load model from 'file:///android_asset/conv_actions_frozen.pb'
    [...]
Caused by: java.io.IOException: Not a valid TensorFlow Graph serialization: Shape must be rank 1 but is rank 0 for 'Mfcc' (op: 'Mfcc') with input shapes: [16000,0,257], [].
    at org.tensorflow.contrib.android.TensorFlowInferenceInterface.loadGraph(TensorFlowInferenceInterface.java:398)
    at org.tensorflow.contrib.android.TensorFlowInferenceInterface.<init>(TensorFlowInferenceInterface.java:97)

我尝试单独寻找解决方案，但导入动态版本可以修复它。如果有另一种解决方法，那也能解决我的问题。

当我尝试访问自述文件中链接的包存储库页面时，我也收到了 404 错误：https://bintray.com/google/tensorflow/tensorflow-android https://bintray.com/google/tensorflow/tensorflow-android

我遇到了同样的错误

java.lang.RuntimeException: Failed to load model from 'file:///android_asset/conv_actions_frozen.pb'

使用tensorflow-android 1.3.0（在这里找到https://mvnrepository.com/artifact/org.tensorflow/tensorflow-android/1.3.0 https://mvnrepository.com/artifact/org.tensorflow/tensorflow-android/1.3.0).

但是，我能够使用夜间构建来运行示例语音识别应用程序（http://ci.tensorflow.org/view/Nightly/job/nightly-android/286/artifact/out/tensorflow.aar http://ci.tensorflow.org/view/Nightly/job/nightly-android/286/artifact/out/tensorflow.aar).

您必须下载 .aar，将其添加到您的项目中并替换

compile 'org.tensorflow:tensorflow-android:+'

与.aar。
