Запуск команды nvprof --metrics под windows выдает ошибку:
==6580== NVPROF is profiling process 6580, command: Project1.exe
==6580== Error: Internal profiling error 4292:1.
======== Error: CUDA profiling error.
error1
Если я использую только команду nvprof, ошибки не будет быть сообщенным:
F:\vstest\Project1\x64\Release>nvprof Project1.exe

Я хотел бы спросить, в чем проблема, как я могу использовать команду nvprof --metrics
