Ominous
commented
3 years ago I tried rebuilding with the exact lines commented out and get a different crash:
Unhandled Exception: 0xe06d7363
KERNELBASE VCRUNTIME140 c10 torch_cpu torch_cpu torch_cpu torch_cpu torch_cpu torch_cpu torch_cpu torch_cpu torch_cpu torch_cpu torch_cpu torch_cpu torch_cpu torch_cpu export_wrapper UE4Editor_LibTorchPlugin!UcDataStorageGameInstance::OnStart() [c:\users\chris-workpc\documents\unreal projects\ai_framework\plugins\basic-unreal-libtorch-plugin\source\libtorchplugin\private\cdatastoragegameinstance.cpp:57] UE4Editor_Engine UE4Editor_UnrealEd UE4Editor_UnrealEd UE4Editor_UnrealEd UE4Editor_UnrealEd UE4Editor_UnrealEd UE4Editor_UnrealEd UE4Editor_UnrealEd UE4Editor_UnrealEd UE4Editor UE4Editor UE4Editor UE4Editor UE4Editor kernel32 ntdll
from this:
52 void UcDataStorageGameInstance::OnStart() 53 { 54 // Calls DLL Function to Activate Camera 55 m_refDataStorageUtil->CallInitCV(); 56 //UE_LOG(LogTemp, Log, TEXT("Opened Camera")); 57 Super::OnStart(); }
Which I guess isolates CallInitCV() ?
I'm not sure how to proceed debugging this.
I have built the dll and installed the plugin, but I am having some trouble that is causing the program to crash when I open the test scene.
UE4 is giving me this as an error:
Unhandled Exception: 0xe06d7363

The context of those 2 calls are: 51 void UcDataStorageWrapper::CallInitCV() 52 { 53 // Calls DLL Function to Activate Camera 54 if (m_funcInitCV == NULL) 55 { 56 UE_LOG(LogTemp, Error, TEXT("Function Not Loaded From DLL: InitNet")); 57 } 58 bool init = m_funcInitCV(); 59 UE_LOG(LogTemp, Error, TEXT("OpenCV Connection Opened %s"), init ? "true" : "false"); }
and
52 void UcDataStorageGameInstance::OnStart() 53 { 54 // Calls DLL Function to Activate Camera 55 m_refDataStorageUtil->CallInitCV(); 56 UE_LOG(LogTemp, Log, TEXT("Opened Camera")); Super::OnStart(); }
However by commenting out the UE_Logs I still get crashes on the same lines so I suspect that it's the call before the said tracebacks.
The only deviation I have from your build instructions is my cmake file for the dll:
I used OpenCV 4.5.2 and therefore have used clarified the use of the OPEN_CV_LIB_DIR
old: set( OpenCV_DIR C:/OpenCV/build) set( OpenCV_INC_DIR C:/OpenCV/build/install/include) set (OpenCV_LIB_DIR C:/OpenCV/build/lib/Release)
${OpenCV_LIB_DIR}/opencv_core412.lib ${OpenCV_LIB_DIR}/opencv_highgui412.lib ${OpenCV_LIB_DIR}/opencv_videoio412.lib ${OpenCV_LIB_DIR}/opencv_imgproc412.lib)
deviation: set( OpenCV_DIR C:/PCTools/opencv-4.5.2_build) set( OpenCV_INC_DIR C:/PCTools/opencv-4.5.2_build/install/include) set (OpenCV_LIB_DIR C:/PCTools/opencv-4.5.2_build/lib/Release)
${OpenCV_LIB_DIR}/opencv_core452.lib ${OpenCV_LIB_DIR}/opencv_highgui452.lib ${OpenCV_LIB_DIR}/opencv_videoio452.lib ${OpenCV_LIB_DIR}/opencv_imgproc452.lib)
Do you know if this deviation may be causing it to fail?
