从tensorflow model下载预训练的模型http://download.tensorflow.org/models/object_detection/ssd_mobilenet_v3_small_coco_2019_08_14.tar.gz

用tensorflow object detection工具

export_tflite_ssd_graph.py   --pipeline_config_path ../ssd_mobilenet_v3_small_coco_2019_08_14/pipeline.config --trained_checkpoint_prefix ../ssd_mobilenet_v3_small_coco_2019_08_14/model.ckpt --output_directory ssd_mobilenet_v3_small --add_postprocessing_op=false

再用

x2paddle --framework=tensorflow --model=ssd_mobilenet_v3_small/tflite_graph.pb --save_dir=ssd_mobilenet_v3_small

用opt检查

./opt --print_model_ops=true --model_dir=ssd_mobilenet_v3_small/inference_model --valid_targets=arm

结果是正确的 “Paddle-Lite supports this model!”

但是

 ./opt --model_dir=ssd_mobilenet_v3_small/inference_model --valid_targets=arm --optimize_out_type=naive_buffer --optimize_out=v3_opt

返回错误
