0 CUDA devices found

[JoshuaC3]

I had the message 0 CUDA devices found within the tutorial notebooks. I think this then results in other issues like java.lang.RuntimeException: Couldnt find any files.

~$ nvcc -V

$ echo $LD_LIBRARY_PATH
/usr/local/cuda-7.5/lib64:

echo $PATH/usr/local/cuda-7.5/bin:

Any more information please ask!

What's the output of nvidia-smi ?

This was the return from nvidia-smi:

I have made a few changes to nvidia drivers/installs and installed CUDA 8 for Ubuntu 16.04. I will have another crack at installing BIDMACH tonight as I have not tried again since the CUDA 8 update.

Any success? Mine only detects one of my two devices.
I have export CUDA_VISIBLE_DEVICES=1,2 set.
Have to use the device number as reported by nvidia-smi. In my case
"export CUDA_VISIBLE_DEVICES=0,1"

[svanschalkwyk]

Try "export CUDa_VISIBLE_DEVICES=0"
