我正在尝试在成功编译cuda-convnet2后运行CIFAR10，我收到此错误
src/nvmatrix.cu(394) : getLastCudaError() CUDA error : kSetupCurand: Kernel execution failed : (8) invalid device function .
我在Zotak Nvidia geforce 750ti GPU上运行Linux。这是日志输出

答案 0 :(得分：1)
您可能需要修改Makefile：
并更改
GENCODE_SM35 := -gencode arch=compute_35,code=sm_35
GENCODE_FLAGS := $(GENCODE_SM35)
到
GENCODE_SM35 := -gencode arch=compute_35,code=sm_35
GENCODE_SM50 := -gencode arch=compute_50,code=sm_50
GENCODE_FLAGS := $(GENCODE_SM50)
因为750Ti具有Compute Capability 5.0。
