Tensorflow: not resolving in gradle

Question

When I opened up Android Studio this morning, I got this error when Gradle tried to sync:

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

As per the instructions in their Github readme, they use a dynamic version (which Android Studio warns me about). It had been working just the day before.

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:

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)

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.

I'm also getting a 404 when I try to go to their package repository page linked to in the readme: https://bintray.com/google/tensorflow/tensorflow-android

It looks like they moved their library to maven (https://mvnrepository.com/artifact/org.tensorflow/tensorflow-android). You can add mavenCentral() to repositories in build.gradle to fix that one. — Cameron, Oct 12 '17 at 07:34
Very interesting, adding mavenCentral() and leaving in the dynamic version actually downloads 1.4.0-rc0, but it still throws an exception when loading the model file — J Brewer, Oct 12 '17 at 17:05
Which version of tensorflow are you using to train the model? I think this exception was getting caused because the version used to train the model is higher than the android version. In my case when I got the exception, I used a recent nightly build to train the model. — Cameron, Oct 12 '17 at 17:55
I'm actually using their sample/tutorial model for the time being. That's a good question though, depending on what version they used to train their sample. It was from around Aug. 16th, which was about the same time they released 1.3 from what I can tell — J Brewer, Oct 12 '17 at 18:20

I got the same error

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

using tensorflow-android 1.3.0 (found here https://mvnrepository.com/artifact/org.tensorflow/tensorflow-android/1.3.0).

However, I was able to get the sample speech recognition app to run using a nightly build (http://ci.tensorflow.org/view/Nightly/job/nightly-android/286/artifact/out/tensorflow.aar).

You'll have to download the .aar, add it to your project and replace

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

with the .aar.

This worked for me too, no exceptions thrown. It's manual but at least it isn't dependent on a repository if they change something – J Brewer Oct 12 '17 at 17:15
what do u mean by replace with aar? do i need to add something to the gradle.build? – Nati Krisi Oct 13 '17 at 03:30
Here's a post explaining how to add an aar library to a project https://stackoverflow.com/questions/16682847/how-to-manually-include-external-aar-package-using-new-gradle-android-build-syst After you have added the aar, you will need to replace compile 'org.tensorflow:tensorflow-android:+' with compile(name:'tensorflow', ext:'aar') in the build.gradle. – Cameron Oct 13 '17 at 05:20

There's a temporary problem where the artifacts were incorrectly removed from jcenter.
