The newest version of Mma 11.1.1 advertises

"Re-enabled GPU support for neural networks for Mac."

But when I install on an Apple MacBook Pro with an NVIDIA GeForce GT 750M GPU, and I do:

Needs["CUDALink`"] 

followed by

CUDAQ[]

I get

False

Does Wolfram not support this GPU?

  • $\begingroup$ I have same GPU/OS/mathematica and I get True. Check that your CUDA works, I've setup CUDA for other applications beforehand. Note though that 750M is quite slow, I get no speed benefit from using GPU implementation for neural net training $\endgroup$ – Yaroslav Bulatov Apr 26 '17 at 1:29

    $\begingroup$ By the way, the neural network functionality is completely independent of CUDALink. $\endgroup$ – ilian Apr 26 '17 at 1:45

    $\begingroup$ As Ilian said, CUDALink and NetTrain's GPU support are entirely different and unrelated things. CUDALink works fine for me on the same hardware (2014 MacBook Pro) with 11.1.0 (but NetTrain does not—I do not yet have 11.1.1). Did you install CUDA on your computer before trying this? $\endgroup$ – Szabolcs Apr 26 '17 at 7:50
