I have installed theano-0.9.0. When I run the program gputest.py using cuda backend. It gives the following output.
WARNING (theano.sandbox.cuda): The cuda backend is deprecated and will be removed in the next release (v0.10). Please switch to the gpuarray backend. You can get more information about how to switch at this URL: https://github.com/Theano/Theano/wiki/Converting-to-the-new-gpu-back-end%28gpuarray%29 Using gpu device 0: GeForce GTX 960 (CNMeM is disabled, cuDNN 5110) [GpuElemwise{exp,no_inplace}(<CudaNdarrayType(float32, vector)>), HostFromGpu(GpuElemwise{exp,no_inplace}.0)] Looping 1000 times took 0.377993 seconds Result is [ 1.23178029 1.61879349 1.52278066 ..., 2.20771813 2.29967761 1.62323296] Used the gpu But if I run the program using gpuarray backend, it gives an error.

I have also tried ldconfig but it didn't work. Kindly help. Thanks, Akshay -- --- You received this message because you are subscribed to the Google Groups "theano-users" group.
