symbol cudaMallocManaged version libcudart.so.11.0 not defined in file libcudart.so.11.0 with link time reference"

[FinDMee1]

When i run the src code which is using Tensor Core i got the problem like this:
"symbol cudaMallocManaged version libcudart.so.11.0 not defined in file libcudart.so.11.0 with link time reference"
and this Code can be compiled & executed on VS as a cuda project(under the windows).

but when i run the src coed which do not use TensoCore(just a VectorAdd),it can compile successfully and can be executed by GPGPU-sim

why this problem occured

GPGPU-sim environment : CUDA11.1 gcc\g++7.5 gdb8.1.1
command:
source setup_environment release
make clean
make

nvcc --cudart shared -arch=sm_70 -o kernel main.cu

[FinDMee1]

use the command:
nvcc -g -o kernel -arch=sm_70 -lcublas -lcurand kernel.cu
after that it occurs a new problem:
cudaSetDevice failed!
