Tensorflowinferenceinterface: Mobilenet For Imagenet : Java.io.ioexception: Not A Valid Tensorflow Graph Serialization

I am trying to run mobilenet model trained over imagenet on Android Tensorflow for object recognition and facing the issue as described below. TensorFlowInferenceInterface: Failed

Solution 1:

The above issue has been resolved by updating the "libandroid_tensorflow_inference_java.jar" and "libtensorflow_inference.so" to the latest version i.e. Tensorflow - 1.4. The latest ".jar" and ".so" files can be found here.

The issue was due to mismatch of Tensorflow versions. Mobilenet classifier trained over ImageNet was built on Tensorflow - 1.3 and was being used for inference on Android with Tensorflow - 1.1.

Solution 2:

It says here in main activity java file

privatestaticfinalStringMODEL_FILE="file:///android_asset/expert-graph.pb";
privatestaticfinalStringLABEL_FILE="file:///android_asset/labels.txt";

Where your model files seems to be "mobilenet_imagenet.pb". After you make sure your model and labels name match for the project file here, change the input size what you trained on.(retrain.py file maybe has this information.)

privatestaticfinalintINPUT_SIZE=160;//privatestaticfinalintIMAGE_MEAN=128;
privatestaticfinalfloatIMAGE_STD=128;
privatestaticfinalStringOUTPUT_NAME="final_result";
