Do you have sample models (xml/bin files) for the sample exes (classification_sample_async.exe) provided ? Also missing dll errors during execution of the exe

Hi,

I am using the NCS-2 for teaching and developing some applications. Both the sample demos (demo_squeezenet_download_convert_run.bat and demo_security_barrier_camera.bat) run fine.

  1. Attempting to run the sample binary classification_sample_async.exe from C:\Users\<MyUserName>\Documents\Intel\OpenVINO\inference_engine_samples_build\intel64\Debug causes a few missing dll errors, namely, inference_engined.dll in C:\Program Files (x86)\IntelSWTools\openvino\inference_engine\bin\intel64\Debug, tbb_debug.dll in C:\Program Files (x86)\IntelSWTools\openvino\inference_engine\bin\intel64\Debug and opencv_imgcodecs412d.dll in C:\Program Files (x86)\IntelSWTools\openvino\opencv\bin whereas I find that these dlls are within the Intel OpenVINO installation itself. I added these to the system path explicitly and then the exe didn't complain. I would need to manually change these paths depending on Debug/Release though. Is this correct or is there an easier automated way ?
  2. However, for inferencing, I need to provide it with sample models (.xml/bin files), I don't see any sample .xml files relevant to the exe. Are there any sample xml and bin files that I can use off-the-shelf to run the exe ? 
  3. Building individual sample applications on Windows causes a CMake error namely, "Unknown CMake command "ie_add_sample" but building all the applications succeeds ! I googled and came across the Intel link https://forums.intel.com/s/question/0D50P00004RxnLg/cmake-errors-of-interactivefacedetectiondemo?lan... -- seems its a known issue as early as 4 months back. Is there a permanent fix yet ? 

 

Thanks for your help !

Thank you for reaching out.

 

1- You will need to change these paths manually, as the system does not know if you want to add them in your command or not.  

 

2- The reason why there isn't a specified model (.xml and .bin) is due to the fact that it's given as a parameter. Also, the reason why he might get those errors with dll when running the .exe from the Debug could be related to unset setenvars.bat not been executed. Please try to use the files from Release instead of Debug. To get the IR files (.xml and .bin) you will need to use the Model Downloader. In order to run the model downloader tool successfully, please check this guide. After installing prerequisites, go to the model_downloader tool folder located in: <OpenVINO_INSTALL_DIR>/deployment_tools/tools/model_downloader.

There you can find the binary file and run the following commands:

 

  • Displays the help menu:
python3 downloader.py --help

 

  • Install the pre-trained model called "MODEL_NAME" in the OUTPUT_DIRECTORY specified:
python3 downloader.py --name MODEL_NAME -o OUTPUT_DIRECTORY

 

3- To build the demos you will need to use build_demos.sh script located in openvino>/deployment_tools/open_model_zoo/demos directory. The script will build all the demos and print the location of the binaries.  

 

Regards,

Mauricio R.
