I have been at this problem for days now... And driving me nuts,

Switching from nd4j-cuda-9.2-platform to nd4j-native-platform in the pom.xml and everything works fine.

Now running at 9.2 (1.0.0-beta4), but I tried different versions of CUDO with and without cudnn. the error is always the same,

CUDA-Z seems to work which makes me think it's not the card or the installation.

path includes: C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.2\bin

CudaEnvironment.getInstance().getConfiguration().getAvailableDevices(); Always returns an empty list.

Was running this card as a second card but now connected to the monitor everything looks fine.

And with native on everything is aok....

Going back to cuda 10.1 without cudnn (to be sure because I read somewhere it might not be compatible with the GTX 460)

fingers crossed...

RIP

Manually looked for the latest driver for the GTX 460 on the NVIDIA website. 391.35 is actually the last one from march 2018. Downloaded and installed it anyway. Also cleaned out the .javacpp folder in the user directory, which had some related stuff in it. Driver DLL version in CUDA-Z showed exactly the same version as before. In the end the same error occurs:

Time for some meditation before the computer goes flying out of the window.

Compiling with Java 8 instead of Java 7: doesn't help.

I think there is my problem. The cuda driver is throwing errors. Guess I was under the false impression that CUDA-Z means everything is fine with the driver. Apparently the driver is too old but because there is no newer one Guess I will need to switch to an even older cuda then 9.2.

Downgrading to cuda 8.0 did the trick. But now ND4J just straight up tells me: CUDA backend requires compute capatibility of 3.0 and above to run.

Card is simply too old. I'll play around with downgrading cuda as well, because after all this time i would like to see it actually run something.. probably slower then the CPU anyway.
