2 cuda versions on my compter

Hi,

On Windows 10, I installed cuda_10.1.243_426.00_win10.exe and driver 441.12. on command prompt, I run command nvcc --version and nvidia-smi, I got the following output:

for nvcc --version command, cuda version is 10.1.243,
for nvidia-smi command, cuda version is 10.2

why are those 2 versions different?

nvcc --version

Including the path to latest Cuda 10.2 version in PATH, should help resolve the ambiguity.
