Hi abhi,
The issue may be with your code used to inference, did you start from scratch or based it off one of our sample apps?
I was able to get detect the person in your image using one of our sample demos. To build the samples, run the build_sample.sh scrip in the <openvino>/inference_engine/samples directory.
I used the following command to run your model and image with the sample app.
Python3 ~/inference_engine_samples_build/intel64/Release/object_detection_sample_ssd -m frozen_inference_graph.xml -i image.jpeg -d MYRIAD

Hi abhi,
Could you please share additional information?
- Please provide the model optimizer command that you used.
- What version of the OpenVINO toolkit are you using?
- Could you provide your model for me to replicate? You can share it with me via private message (click my username, on my profile click send message and attach the model)
- What version of Tensorflow did you use to train the model?
Regards,
Jesus

- First of all I used this tutorial to train my ssd mobilenet v1 coco mode: https://github.com/jaspereb/FasterRCNNTutorial
- I have trained my model on Tensorflow: 1.13.1(you can find all the other details in my tensorflow issue...readed to cuda etc https://github.com/tensorflow/tensorflow/issues/30776)
- Command I used: python3 mo_tf.py --input_model frozen_inference_model.pb
- I'm using OpenVino_2019.1.144 on mac
- My model: Sent in PM

Hi abhi,
Thank you for sending your model over. I was not able to convert it using the model optimizer. I am not familiar with the tutorial and have not gone though it myself. However, the tutorial mentions using faster_rcnn_resnet101_coco as the base model prior to training. Which model did you use?
Please update your OpenVINO toolkit to the latest release (2019 R2) that was released today. Using the latest release, I converted the faster_rcnn_resnet101_coco model with the following command:
python3 ~/intel/openvino/deployment_tools/model_optimizer/mo_tf.py --input_model frozen_inference_graph.pb --tensorflow_use_custom_operations_config ~/intel/openvino/deployment_tools/model_optimizer/extensions/front/tf/faster_rcnn_support.json --tensorflow_object_detection_api_pipeline_config pipeline.config -b 1 --data_type FP16
Could you try and see if you are able to convert the model? For your custom trained model, you would need to use the faster_rcnn_support_api_1.1x.json to match your version.
-- tensorflow_use_custom_operations_config
~/intel/openvino/deployment_tools/model_optimizer/extensions/front/tf/faster_rcnn_support_api_v1.x.json
Also, try to freeze your model with the steps mentioned in the following document:
https://docs.openvinotoolkit.org/latest/_docs_MO_DG_prepare_model_convert_model_Convert_Model_From_TensorFlow.html#freeze-the-tensorflow-model
If you get any errors, please add the --log_level=DEBUG to your mo_tf command and send me the following information.
- New frozen model with the steps above
- pipeline.config file
- command used
- full log file of the mo_tf command

Jesus

@Intel_Jesus I have used the model I wrote in question. This model :http://download.tensorflow.org/models/object_detection/ssd_mobilenet_v1_coco_2018_01_28.tar.gz
I've compiled the model with TensorFlow version 1.13(just in case). It seems that tf version matching matters a lot. Thanks to @Aroop_at_Intel for that
Also you used ~/intel/openvino/deployment_tools/model_optimizer/extensions/front/tf/faster_rcnn_support.json
for mobiletnet ssd v1 coco what should I use? tf/ssd_support.json????
I'm retraining model zoo pre-trained models & retaining for custom object detection....Can you please pick the model I gave you....tar.gz & train that? See if that works? If that works...custom trained should also work

Hi abhi,
The ssd_support.json is only for frozen SSD topologies from the models zoo. Since you trained your own network, you will need to use ssd_support_api_v1.14.json found in the ~/intel/openvino/deployment_tools/model_optimizer/extension/front/tf directory.
I was able to convert your frozen model using the OpenVINO toolkit R2 2019 using the following command:
python3 ~/intel/openvino/deployment_tools/model_optimizer/mo_tf.py --input_model frozen_inference_graph.pb --tensorflow_use_custom_operations_config ~/intel/openvino/deployment_tools/model_optimizer/extension/front/tf/ssd_support_api_v1.14.json --tensorflow_object_detection_api_pipeline_config pipeline.config -b 1 --data_type FP16 --reverse_input_channels

I used the pipeline.config file included in the pre-trained model you used and changed the num_classes to match your model (num_classes: 1).

@Intel_Jesus the inference is not working ...I used this file for inference (openvino r1) installed on raspberry pi for inference....
Can you share me something about inference on how do I check that?
This is the file I used for inference. The class is person

SyntaxError: Non-UTF-8 code starting with '\xcf' in file object_detection_sample_ssd on line 1, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details
My python version is 3.7.3. Is that causing the problem? Looks like something has changed in pep standards

Also @Intel_Jesus I have just converted a YOLO(Darknet) -> Tensorflow -> OpenVino(XML, BIN, etc)
but what's in for detection? object_detection_sample_ssd is for ssd. What do I use for detection on YOLO & end thing is deploying it on NCS2 + Raspberry...& detect with WebCAM continously
So please help me with that also. Like explain me further steps. Any link or anything

Hi Abhi,
This discussion is getting too long and deriving from the original question. Could you please open a new discussion for the YOLO (darknet) question.
The latest release of OpenVINO R2 2019 for the Raspberry Pi does not have the samples for object detection ssd. I was able to run your model on R2 2019 using my Raspberry Pi using the next steps.
- Install R2 2019 on the Raspberry Pi following the instructions here: https://docs.openvinotoolkit.org/latest/_docs_install_guides_installing_openvino_raspbian.html
- Download the R1.1 OpenVINO package, extract and run the sample with your model using the following steps.
cd ~/Downloads
wget https://download.01.org/opencv/2019/openvinotoolkit/R1/l_openvino_toolkit_raspbi_p_2019.1.144.tgz
tar -xf l_openvino_toolkit_raspbi_p_2019.1.144.tgz
cd inference_engine_vpu_arm/inference_engine/samples/python_samples/object_detection_demo_ssd_async
python3 object_detection_demo_ssd_async.py -m frozen_inference_graph.xml -d MYRIAD -i cam
It's possible your previous error was due to a corrupted file and not the python version. I used python version 3.5.3. To use a webcam with the raspberry pi, you can use -i cam.

Jesus

So, a R2 compiled version can used on 2019 R1.1.144 for inference?
So what I understood is. Install R2 2019 on raspbi. But use R1.1 for inference?

I have used build_sample.sh and everything passed well without any error. What seems corrupted? .XML converted model or object_detection_ sample_ssd?
