NCS2 - smart_classroom_demo - [ ERROR ] [NOT_FOUND] DYN_BATCH_ENABLED key does not exist

[Shiba__Sidney]

Hello,

I have installed OpenVINO 2018R4 (Build date:12 Nov 2018) on a Ubuntu 16.04 VM and when running the demo smart_classroom_demo I got the following error " [ ERROR ] [NOT_FOUND] DYN_BATCH_ENABLED key does not exist". Note that NCS2 stick is plugged and working. Tested on another demo without any problem.

See the execution trace below:

<TRACE>

I couldn't find any information on this error. Can anybody help resolving this issue?

Thanks in advance.

Dear Sidney, 

the movidius stick does not support dynamic batch feature which is activated for all models in the smart_classroom demo. Also our documentation shows that 2 models landmarks-regression-retail-0009 and  person-detection-action-recognition-0003 are not supported on Movidius: deployment_tools/documentation/docs/_docs_IE_DG_Samples_Overview.html

Therefore, you should run this demo with CPU or GPU. 

Finally, in case, you are interested in running it in CPU, you have the models at the wrong arguments in the command line, here is the correct order. 

smart_classroom_demo.exe -m_act $MODELS\person-detection-action-recognition-0003\FP32\person-detection-action-recognition-0003.xml -m_fd $MODELS\face-detection-retail-0004\FP32\face-detection-retail-0004.xml -m_lm $MODELS\landmarks-regression-retail-0009\FP32\landmarks-regression-retail-0009.xml -m_reid $MODELS\face-reidentification-retail-0071\FP32\face-reidentification-retail-0071.xml -d_act CPU -d_fd CPU -d_lm CPU -d_reid CPU

Best, 

Severine

Dear Severine,

are there any plans making the smart_classroom demo available for raspberry Pi in combination with the NCS2?

Kind regards,

Niels
