I have been trying to install Cuda for GPU computing with Theano and Tensorflow and it’s been incredibly frustrating to say the least. I’ve tried many methods, all with a fresh install of Ubuntu 14.04, and my most successful attempts have been following these links: nvidia - Has anyone successfully installed CUDA 7.5 on Ubuntu 14.04.3 LTS x86_64? - Ask Ubuntu Signal Processing Turtle: CUDA 8.0 and Theano Setup in Ubuntu linux for Deep learning
After going through these processes, I’ve been able to run the Cuda Samples successfully, but after reboot, theano does not work with the GPU, the command ‘nvcc -V’ tells me to install the cuda toolkit and nvidia commands no longer work. Upon inspection, cuda path files and important nvidia files are no longer in the folders they should be in.
As I said, I am running Ubuntu 14.04 and am relatively new to Linux, I am trying to install cuda 7.5, my computer is a Dell Precision T5500 with a 0CRH6C motherboard and my GPU is a Nvidia GeForce GTX 470. I have been able to successfully install the Nvidia drivers with the X Server application seeming to work well, but without Cuda, for a couple weeks. Finally, the command ‘lspci | grep -i nvidia’ always recognizes my gpu.
Any ideas? Thanks in advance.
