R2Inference provides several examples to highlight its usage with different architectures and frameworks. The models used for these examples can be downloaded from our Model Zoo.

Preparation

To test the EdgeTPU example you will need a Tensorflow-Lite C++ API and EdgeTPU API compatible graph file. You can obtain the model from the Model Zoo.

Inception v2

This example is located in r2inference/examples/r2i/edgetpu . To use this example run:

./inception -i [JPG input Image] -m [Tflite Model] -s [Model Input Size]

For example, evaluating this image:

Inception example input

Should produce the following output:

./inception -i Plane_example_input.jpg -m inception_v2_224_quant_edgetpu.tflite -s 224
