Hi,
Problem:
I have a weird problem with my Matlab 2019b installation (academia version).
I am trying to train a feedforward neural network, using my gpu, but Matlab keeps telling me that "gpu.dll is not a valid Win32 application.".
I can replicate that error when I try to read the gpu informations in Matlab:
>> count = gpuDeviceCount
count =
1
>> gpu1 = gpuDevice(1)
Failed to load library: gpu.dll, error was: gpu.dll is not a valid Win32 application.
What I tried so far without success:
  • installed the newest graphics driver
  • reinstalled Matlab 2019b
  • verification of windows files ( SFC /scannow )
My system:
Windows 10 home, Intel i5-7600K CPU, NVIDIA GeForce GTX 1060 6GB GPU
I also know that the GPU has CUDA support and I used it in the past with different software (not recently though).

This could mean there is a corrupted file in your installation. Could you please contact our technical support and we'll be able to get you sorted.

@Walter Roberson:
I updated the driver this morning, around 12h ago. The driver before was older and was installed when I bought the desktop (2 years). I didn't make a difference
@Alison Eele:
I tried reinstallation of Matlab, first installing it over the current installation and then removing the old one first and installing it completely new. Did not make a difference.
I will contact the technical staff tomorrow. I was hoping it is a common problem with an easy solution.
