vl_compilenn error

Hello,

I tried running the following:

     vl_compilenn('enableGpu', true, ...
'cudaMethod', 'nvcc', ...
'cudaRoot', 'C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.5', ...
'enableCudnn', true, ...
'cudnnRoot', 'local/cudnn') ;

Before I added to 'C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.5\bin\nvcc.profile' the flag:

CUDA_NVCC_FLAGS = --cl-version 2010

(I also tried CUDA_NVCC_FLAGS += --compiler-bindir = "C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin")

But the error is the following:

    vl_compilenn:  CUDA: MEX config file: 'C:\Program Files\MATLAB\R2016b\toolbox\distcomp\gpu\extern\src\mex\win64\mex_CUDA_win64.xml'

Error in vl_compilenn (line 466)
      nvcc_compile(opts, srcs{i}, objfile, flags.nvcc) ;

Can anyone help? Perhaps some more Informations: I have installed Microsoft Visual Studio Express 2010. My Comp has the specifications Wind 7, 64 bit, I'm using Matlab 2016b

It looks like 'vl_compilenn' is from a third-party repo called 'MatConvNet' which has its own forums at the following links. You may want to check there as well.

From MATLAB perspective, MATLAB may not be setup with a compiler supported by this functionality. Execute the following command and make sure that your Visual Studio 2010 compiler is selected as the default compiler.

>> mex -setup

Hope this helps!
