System.AccessViolationException: 'Attempted to read or write protected memory
System Windows 10 VS 2022
Download samples and tried to run the program: OnnxObjectDetection
Complies correctly and when I run the program an unhandled exception is thrown on line 25 var pipeline.
"An unhandled exception of type 'System.AccessViolationException' occurred in Microsoft.ML.OnnxRuntime.dll Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
The program '[19772] OnnxObjectDetectionApp.exe' has exited with code 3221225477 (0xc0000005) 'Access violation'."
Tried running VS 2022 as administrator and same issue. Tried changing to x64, x86, and Any CPU and same issue. Even rebooted same issue. Stuck.
Other samples such as DeepLearning_ObjectDetection_Onnx work fine, no issues.
Thank you.
Try updating OpenCvSharp-AnyCPU to OpenCvSharp4. Also install the runtime for your OS. In case of Windows that is OpenCvSharp4.runtime.win
To be sure, you can also update the Microsoft.ML.* packages.
Windows 10 VS 2022 .Net 6
Confirming that updating Microsoft.ML packages (to 1.7.1) and changing .Net target to .Net 6 worked for me. I did not need to make any changes to OpenCvSharp.
Windows 10 VS 2022 .Net 6
Tried the workaround suggested by @michaeltclark and it did NOT work for me.
