tflite

1、编译libtensorflow-lite.a库：

ubuntu下交叉环境编译：

2、将pb模型转为tflite

      tflite_convert --output_file MTCNN_mobile/pnet.tflite --graph_def_file frozen_graphs/pnet.pb --input_arrays "input" --input_shapes "1,600,800,3" --output_arrays cls_prob,bbox_pred,landmark_pred --output_format TFLITE

3、将tflite模型量化

     官方例子： https://github.com/tensorflow/tensorflow/blob/master/tensorflow/lite/tutorials/post_training_quant.ipynb

github上的一些使用例子：

在树莓派下测mtcnn，速度慢成狗，弃坑
