Error: could not insert 'nvidia_352' after Installing Cuda on EC2 g2.2xlarge

Question

After launching Ubuntu Server 14.04 LTS (HVM), I tried to install CUDA as following

wget http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1404/x86_64/cuda-repo-ubuntu1404_7.5-18_amd64.deb
sudo dpkg -i cuda-repo-ubuntu1404_7.5-18_amd64.deb
sudo apt-get update
sudo apt-get install -y cuda
export PATH=/usr/local/cuda-7.5/bin:$PATH 
export LD_LIBRARY_PATH=/usr/local/cuda-7.5/lib64:$LD_LIBRARY_PATH
sudo reboot

Then I run a test

cuda-install-samples-7.5.sh .
cd ~/NVIDIA_CUDA-7.5_Samples/1_Utilities/deviceQuery 
make  
./deviceQuery

got the error:

modprobe: ERROR: could not insert 'nvidia_352': Unknown symbol in module, or unknown parameter (see dmesg) cudaGetDeviceCount returned 38 -> no CUDA-capable device is detected

What could be wrong here?

Answer 1

Upgrade Ubuntu and install linux-image-extra before install nvidia-driver sudo apt-get update && sudo apt-get -y upgrade sudo apt-get install -y linux-image-extra-`uname -r`

Answer 2

It would appear that this is a known issue within CUDA 7.5 on AWS gpu instances. The short term work around seems to be to downgrade to CUDA 7 for the moment.

Edited in December 2015 to add that Robert Crovella from NVIDIA advises that CUDA 7.5 on EC2 g2.2xlarge should now be usable with a 352.63 or later driver. So a driver update should resolve the issue.
