标题: error to convert ssd_mobilenet_v2_coco_2018_03_29
I modifed ssd-model.py to conver convert ssd_mobilenet_v2_coco_2018_03_29 to RKNN as below.

rknn.load_tensorflow(tf_pb='./ssd_mobilenet_v2_coco_2018_03_29/frozen_inference_graph.pb')
inputs=['FeatureExtractor/MobilenetV2/MobilenetV2/Conv2d_0/BatchNorm/batchnorm/mul_1'],

But I got the following errors:

--> Loading model

Any idea why this happens?

Please use rknntoolkit 0.9.8 try again, initializing with verbose argument, and it will print more error info to us.

Below is output of rknn-toolkit-v0.9.8 with verbose=True:

Are you able to find out why ssd_mobilenet_v2_coco_2018_03_29 model can not work with RKNN tool?

Thanks,

This model, http://download.tensorflow.org/m ... o_2018_01_28.tar.gz is OK.
But this one, v2, http://download.tensorflow.org/m ... o_2018_03_29.tar.gz is not OK.
The error is below using RKNN-0.9.8:

Can you download http://download.tensorflow.org/m ... o_2018_03_29.tar.gz to reproduce it?

This model, http://download.tensorflow.org/models/object_detection/ssd_mobilenet_v1_coco_2018_01_28. ...

我今天在测试时也发现了，好像只有 V1 版本能转， V2 或者 V1 其它数据集的都又这个问题，是不支持某些 OP 么？

作者: pangu 时间: 2019-2-16 10:04
Agreed. I even try export_inference_graph on ssd_mob ile_v1_coco below and use the frozen pb with ssd.py, I got the same error again.

python3 ./src/models/research/object_detection/export_inference_graph.py \
--input_type image_tensor \
--pipeline_config_path ssd_mobilenet_v1_coco_2018_01_28/pipeline.config \
--trained_checkpoint_prefix ssd_mobilenet_v1_coco_2018_01_28/model.ckpt \
--output_directory object_detection_graph

It seems rknn model converter tool is not mature and hope RK eng can fix it asap. Otherwise, we can not use it for our own trained model

这个问题解决了么？

作者: yhc 时间: 2019-2-18 12:02
mobilenet v2的input和v1是不一样的，请用参考下面代码

    

rknn.load_tensorflow(tf_pb='./ssd_mobilenet_v2_coco_2018_03_29/frozen_inference_graph.pb',

                         inputs=['FeatureExtractor/MobilenetV2/MobilenetV2/input'],

                         outputs=['concat', 'concat_1'],

                         input_size_list=[[300, 300, 3]])
