title: Tensorflow: not resolving in gradle
body: <p>When I opened up Android Studio this morning, I got this error when Gradle tried to sync:</p>
  
  <pre><code>Error:(103, 13) Failed to resolve: org.tensorflow:tensorflow-android:+
  </code></pre>
  
  <p>As per the instructions in their <a href="https://github.com/tensorflow/tensorflow/tree/master/tensorflow/contrib/android" rel="nofollow noreferrer">Github readme</a>, they use a dynamic version (which Android Studio warns me about). It had been working just the day before.</p>
  
  <p>I did try using the only explicit version they have: 1.3.0, but this leads to another problem when trying to load their speech recognition model with their sample code:</p>
  
  <pre><code>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.&lt;init&gt;(TensorFlowInferenceInterface.java:97)
  </code></pre>
  
  <p>I've tried searching for a solution to that separately, but importing the dynamic version fixes it. If there was another workaround, that would also solve my problem.</p>
  
  <p>I'm also getting a 404 when I try to go to their package repository page linked to in the readme: <a href="https://bintray.com/google/tensorflow/tensorflow-android" rel="nofollow noreferrer">https://bintray.com/google/tensorflow/tensorflow-android</a></p>
