# edgetpu-native
edgetpu-native from https://coral.googlesource.com/edgetpu-native
See [here](https://github.com/freedomtan/edge_tpu_python_scripts) for scripts using [Python API](https://coral.withgoogle.com/docs/edgetpu/api-intro/)
Added modified `label_image for tflite` and related updates so that we can build it on Coral Dev Board.
```
bazel build edgetpu/cpp/examples/label_image:label_image
```
Then we can get
```
bazel-bin/edgetpu/cpp/examples/label_image/label_image
```
With that, we can use it to run either original quantized TFLite models on CPUs or Edge TPU's canned models on Edge TPUs. E.g., with
```
bazel-bin/edgetpu/cpp/examples/label_image/label_image \
-m ~/work/edge_tpu_data/mobilenet_v1_1.0_224_quant_edgetpu.tflite \
-i ~/work/data/grace_hopper.bmp \
-l ~/work/data/labels.txt \
-c 50
```
I got
```

0.00392157: 922 922:book jacket, dust cover, dust jacket, dust wrapper
```
With
```
bazel-bin/edgetpu/cpp/examples/label_image/label_image \
-m ~/work/edge_tpu_data/mobilenet_v1_1.0_224_quant.tflite \
-i ~/work/data/grace_hopper.bmp \
-l ~/work/data/labels.txt \
-c 50
```
I got

0.0352941: 458 458:bow tie, bow-tie, bowtie

With `-v`, we can see many interesing information
