error in vl_compilenn('enableGpu',true)

[JEBA97]

I get the following error while compiling the Gpu.. Can someone help me out

vl_compilenn('enableGpu', true,'Verbose',1) vl_compilenn: CUDA configuration vl_compilenn: CUDA: searching for the CUDA Devkit (use the option 'CudaRoot' to override): | valid | ver | NVCC path | | 0 | 0 | | | 0 | 0 | C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v5.5\bin\nvcc.exe | | 0 | 0 | C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v6.0\bin\nvcc.exe | | 0 | 0 | C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v6.5\bin\nvcc.exe | | 0 | 0 | C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.0\bin\nvcc.exe | | 0 | 0 | C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.5\bin\nvcc.exe | | 0 | 0 | C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0\bin\nvcc.exe | | 0 | 0 | C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.5\bin\nvcc.exe | | 0 | 0 | C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0\bin\nvcc.exe | | 0 | 0 | C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.5\bin\nvcc.exe | | 0 | 0 | C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0\bin\nvcc.exe | | 0 | 0 | /usr/local/cuda/bin/nvcc | Error using vl_compilenn>search_cuda_devkit (line 715) Could not find a valid NVCC executable\n
