Hi
I want to go through the GPU compilation with THEANO on 64 bit Ubuntu
16.04; CUDA 7.5.
I tried the test code given on site:
http://deeplearning.net/software/theano/tutorial/using_gpu.html
I installed Theano, Cuda toolkit.
But I am getting following error.
Why it is occuring and how can I overcome this.
THEANO_FLAGS=mode=FAST_RUN,device=gpu,floatX=float32 python check1.py
WARNING (theano.sandbox.cuda): CUDA is installed, but device gpu is not
available (error: Unable to get the number of gpus available: unknown
error)
Traceback (most recent call last):
