Hi,
I am trying to find the accuracy of my ssd lite mobilenet model for object detection(tensorflow).
I tried using validation_app tool and I am getting 0 for two classes and total accuracy is below 1%. But I am getting decent detection while inferring using object_detection_ssd sample. I tried with 2019 R1, R2 and 2018 R4,R5 but still getting very low accuracy or 0 accuracy.
I tried to use workbench tool in 2019 R2 also, but it seems like it only takes Pascal VOC dataset only for object detection.
can you suggest me any tool or page to calculate the accuracy of my model?

Dear K, Kannan,
yes you are correct - the DL Workbench tool is limited in the number of data sets it supports as it's in Preview Mode for R2. In future releases it should support more.
You're better off doing it manually using the Python Tools. In dldt github issue 171 i give the poster detailed steps on how to accomplish it.
Please continue to use OpenVIno 2019R2 as it contains many bug fixes and improvements.
Hope it helps !
Thanks,
Shubha

Thanks Shubha, for the quick reply.
I followed the steps you specified in the github page for getting accuracy using accuracy_checker tool.
I am able to successfully convert the dataset, but while running the accurcy_checker python code I am facing the below error. The model I am using is ssd lite mobilenet v2 and tried with 2019 R2

Dear K, Kannan,
Hmmm. This seems to be coming from Model Optimizer "under the hood". Are you able to generate IR for this model with model optimizer ?
Unsupported primitive of type: PriorBoxClustered name: PriorBoxClustered_5
Means exactly what it says - a layer is used which is not supported by Inference Engine. But according to Model Optimizer Supported Tensorflow List in fact SSD Lite MobileNet V2 COCO is supported. Did you use the download link provided here ? And are you for sure trying with OpenVino 2019R2 since SSD lite is new to 2019R2.
Please report back on this forum.
Thanks,
Shubha

Hi Subha,
Thanks again for the reply.
I am trying accuracy checker tool with using IR file generated on R2. and I did transfer learning on the model.
The same model is inferring fine with object_detection_demo_ssd_async sample.

Dear K, Kannan,
Which *.yml file did you use for the --config argument to accuracy_check.py ? I am thinking that this is what is wrong, you're either using the wrong one or an incorrect one.
Please let me know.
Thanks,
Shubha

Dear K, Kannan
I confirmed that we don't have an ssd lite ssd lite mobilenet v2 config.yml. I'm not sure which yml you are using. But if you're not using a proper one designed for ssd lite ssd lite mobilenet v2 then you will get errors. You can certainly devise one - and if you do, accuracy_check.py should work. Please look at existing yml examples in the C:\Program Files (x86)\IntelSWTools\openvino_2019.2.242\python\python3.7\openvino\tools\accuracy_checker\configs directory.
Hope it helps,
thanks,
Shubha

Dear K, Kannan,
Before we complicate matters by involving accuracy_check.py can you even use regular old Model Optimizer to generate IR on your model ? First please try that on OpenVino 2019R2.

Hi Subha,
To be clear, I am trying to get the accuracy of my model using the IR files that I converted using OpenVINO R2 like I mentioned earlier.
I converted my ssd lite mobilenet v2 model to IR using openvino R2:-

Dear K, Kannan ,
I understand the distinction. I am just trying to narrow down the error. You are getting the below error at runtime (Inference Engine):
self.exec_network = self.plugin.load(network=self.network, num_requests=requests_num)
File "ie_api.pyx", line 551, in openvino.inference_engine.ie_api.IEPlugin.load
File "ie_api.pyx", line 561, in openvino.inference_engine.ie_api.IEPlugin.load
RuntimeError: Unsupported primitive of type: PriorBoxClustered name: PriorBoxClustered_5
Upon running accuracy_check.py . Are you sure you're passing in the correct model_optimizer to -M ? What about --tf_custom_op_config_dir ?
Please post your entire command for accuracy_check.py here.
Also looking at your config.yml it doesn't look complete. Please study c:\Program Files (x86)\IntelSWTools\openvino_2019.2.242\deployment_tools\tools\calibration_tool\configs\ssd_mobilenet_v1_coco.yml for an example. For instance your *.yml is missing
mo_params:
data_type: FP32
tensorflow_use_custom_operations_config: ssd_v2_support.json
tensorflow_object_detection_api_pipeline_config: ssd_mobilenet_v1_coco.config
If you are using certain MO params in your model optimizer command then you need to specify those also in your config.yml.
Also please look at c:\Program Files (x86)\IntelSWTools\openvino_2019.2.242\python\python3.7\openvino\tools\accuracy_checker\README.md
Start with a simple version of the command as the document describes:
accuracy_check -c path/to/configuration_file -m /path/to/models -s /path/to/source/data -a /path/to/annotation
Sadly --h doesn't work, it throws an exception (I'm going to write a bug on that). And the latest R2 documentation doesn't even mention some of the options of that github issue 171 which I earlier referred you to.
Thanks,
shubha
