Fail to convert project to cpp #49

Closed Mrmiffo closed 5 years ago

Mrmiffo commented 5 years ago

Plugin version: tensorflow-ue4.22-v0.13.0-cpu UE4 version: 4.22.3 Visual Studio Community: 2017 15.9.14

Issue: When converting the project from a Blueprint only as per the documentation and https://allarsblog.com/2015/11/04/converting-bp-project-to-cpp/ , the build fails when building with the configuration set to Development. Visual studio throws two errors: Severity Code Description Project File Line Suppression State Error C2039 'SetCurrentLevel': is not a member of 'UWorld' TensorFlowExamples D:\Unreal Projects\tensorflow-ue4-examples\Plugins\UnrealEnginePython\Source\UnrealEnginePython\Private\UObject\UEPyWorld.cpp 319

and Severity Code Description Project File Line Suppression State Error MSB3075 The command ""D:\Unreal Engine\UE_4.22\Engine\Build\BatchFiles\Build.bat" TensorFlowExamples Win64 Development -Project="D:\Unreal Projects\tensorflow-ue4-examples\TensorFlowExamples.uproject" -WaitMutex -FromMsBuild" exited with code 5. Please verify that you have sufficient rights to run this command.

I've tried both using one of the UE4 template projects, an empty newly created project, as well as the tensorflow-ue4-examples project. All fail with the same issue.

If I try to package the project without converting the python code will not run, but the game will start. If I try to package the project after the failed conversion UE4 will fail with the same error. Building with configuration Development Editor is successful.

Steps to recreate:

  1. Create a new UE4 project (UE4 4.22.3)
  2. Add the Plugins folder from tensorflow-ue4.22-v0.13.0-cpu.7z
  3. Start the project
  4. Create a new .cpp file, let UE4 compile
  5. Open visual studio, select configuration Development Editor
  6. Right-click project name and select Build, build successful
  7. Change configuration to Development
  8. Right-click project name and select Build, build fails with the above errors.

Am I doing something wrong? :)

Found a solution in the thread of issue #16

In UEPyWorld.cpp change the following code: if (world->SetCurrentLevel(level)) Py_RETURN_TRUE;

To: `#if WITH_EDITORONLY_DATA if (world->SetCurrentLevel(level)) Py_RETURN_TRUE;

endif`
