Troubleshooting Guide

This chapter contains users in the use AIVT-OV Common error types and workaround during the toolkit process, covering typical issues during the installation, activation, model run, image acquisition, and deployment phases.

If you encounter the following problems, you can refer to the content of this page first. If it still cannot be solved, please contact technical support.


1. Installation and Activation Issues

Problem DescriptionPossible causesSolution
After tool kit installation LabVIEW Unable to load function panelNot installed correctly VIPM Package or not restarted LabVIEWPlease reinstall .vip package, restart after installation LabVIEW
License Manager Startup exception or interface not displayedToolkit not registered properly, dependency not loadedRerun LabVIEW, open as administrator
Prompt "Activate" on activation failed”License ID/Key Input error or network exceptionCheck ID and Key Is it correct; ensure that it is connected to the Internet
Unrecognized when activated offline .lic FileWrong file path or bind device mismatchMake sure .lic From the official, with this machine Computer ID Consistent; path without Chinese spaces

2. model running class problems

Problem DescriptionReasonSolution
Model inference VI Error reportingInvalid model path or incompatible model formatCheck whether the model path is correct, recommend using English path, no Chinese
inference result is empty, no targets detectedInput image size does not match / Category file errorCheck whether the model input size is 1 × 3 ×HxW and whether the category file is one type per line.
OpenVINO Model loading failedModel structure is not standard / Wrong input channelIt is recommended to use Netron View the model structure or replace the official sample model.
inference stuck or too slowUse CPU inference or resolution too largeSwitchable GPU inference devices (Intel A770/iGPU), or resize the image

3. image acquisition problems

Problem DescriptionPossible causesSolution
Camera screen cannot be openedNot connected or drive abnormalCheck Device Manager; try using USB Camera, check whether the camera software provided by the computer can be used to open the camera meat
Failed to read video fileWrong path or unsupported file formatIt is recommended to use .mp4,.avi formatting; paths as absolute
The camera screen is black but no error is reported.Camera connection succeeded but image channel errorTry to change the channel number; confirm that the camera resolution and frame rate are set properly
Industrial Camera Acquisition No ResponseVendor driver not loaded or not initializedInstall the appropriate brand SDK and confirm LabVIEW Call interface initialization is normal

4. deployment run class issues

Problem DescriptionReasonSolution
After packing EXE Start flash backWrong model path or missing dependencyCheck whether all model/category names/image files are included; Log records can be added for troubleshooting.
Deployment side cannot be loaded License ManagerRuntime library is missing or does not contain VI DependencyWhen packaging, ensure that the dependencies are checked and recommend used. Installer Packing
EXE Prompt "Unauthorized to run" after running"No deployment activation or activation failedSee Project deployment and distribution Execute the deployment authorization process

5. Path and File Problems

Problem DescriptionReasonSolution
The program run could not find the model or category name fileThe model path is written to the development machine path.Use the control instead to pass in a relative path, avoiding hard-coding the path
Error reported when model path is in ChineseOpenVINO Load path does not support ChineseAll paths should be English folders; avoid spaces and Chinese characters
Picture set selection cannot display imagesImage format not supported or path errorSupport .jpg/.png Common formats such

🛠 Troubleshooting Suggested Process

No_278A Is the model loaded? → Is the model path correct? No_279 Is the image acquired normally? → Is the camera or image path valid? 2. Output inference results? → Are the input dimension and category files correct? Noted Is it wrong? → View VI Error information and locate the corresponding function What Authorized? → Check license activation status


Other troubleshooting assistance

  • available in VI Add a "logging" module to output key operating information such as model path and device status.

  • It is recommended to add the front panel "Debug" mode for outputting intermediate result images or intermediate variables

  • Keep the error window in the deployment program to help users locate the problem on site


Technical Support

If you are still unable to resolve the issue, please contact the technical support team:

Please submit the issue with the following information:

  • Currently used LabVIEW version and number of digits (e. g. 2021 SP1 64-bit)

  • OS version (e. g. Windows 10 22H2 x64)

  • Toolkit version number used (can be viewed in the Update Record or VIPM)

  • The specific module in question (e. g. OpenVINO / ModelZoo / PaddleOCR etc.)

  • Problem screenshot or error message

  • If it is a model loading problem, please attach a screenshot of the model file path and model structure (available. netron.app View)

📌 It is recommended that you indicate "[AIVT-OV failure consultation]" in the mail header, and we will give priority to response.

Thank you for your support and understanding.
