Does MEX acceleration for Deep Learning need a GPU Coder license?

Does MEX acceleration for Deep Learning need a GPU Coder license?

I see the following error message:

coder.checkGpuInstall
Compatible GPU           : PASSED 
CUDA Environment         : PASSED 
Runtime   : PASSED 
cuFFT     : PASSED 
cuSOLVER  : PASSED 
cuBLAS    : PASSED 
cuDNN Environment        : PASSED 
Error using coder.checkGpuInstall (line 32)
Undefined variable "coder" or class "coder.gpuConfig".

"The 

'mex'

 option is only available when you are using a GPU. You must also have a C/C++ compiler installed. For setup instructions, see MEX Setup (GPU Coder).\n

'mex' acceleration does not support all layers. For a list of supported layers, see Supported Layers (GPU Coder)."

Answer 1

[MathWorks Support Team]

MEX acceleration for the Deep Learning Toolbox does not require the GPU Coder Toolbox, it only needs the following Support Package: https://www.mathworks.com/matlabcentral/fileexchange/68642-gpu-coder-interface-for-deep-learning-libraries

We will state this clearer in a future release of our documentation.
