I've tried to install CUDA on three different VMs but have been unsuccessful in getting it to recognize my GPU.

I am using an Azure VM (Standard NV6) with an M60 GPU.

With a fresh VM I run the following commands taken from this guide:

wget https://developer.nvidia.com/compute/cuda/8.0/Prod2/local_installers/cuda-repo-ubuntu1404-8-0-local-ga2_8.0.61-1_amd64-deb sudo dpkg -i cuda-repo-ubuntu1604-8-0-local_8.0.44-1_amd64-deb sudo apt-get update sudo apt-get install -y cuda

It appears to run successful and doesn't indicate that there were any problems. But when I run

nvidia-smi

I receive the following:

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running

I have tried with 16.04 LTS and various other GPU instances. Google tells me others are using these Azure GPU instances with Tensorflow, so it doesn't appear to be an issue with the graphics card.

Finally, I have reviewed what seems to be the canonical guide to installing CUDA on Ubuntu but it fails when running 

sudo ./NVIDIA-Linux-x86_64-331.62.run

enter image description here

The message in the log file:

ERROR: Unable to load the 'nvidia-drm' kernel module.

My Question

What is the most reliable method for installing CUDA 8 on Ubuntu 14.04 LTS?

Are there any special precauations that I need to take when running CUDA on a VM?

Edit: Additional Info

  • What sort of a VM does the Azure service provide? What do uname -a and lsmod report? Commented Feb 23, 2017 at 10:13
  • I've appended that info near the end of my question. Let me know if you need anything else. Commented Feb 24, 2017 at 6:03

The official Azure documentation points out:

Currently, Linux GPU support is only available on Azure NC VMs running Ubuntu Server 16.04 LTS.+

I'm not sure why they even let you create GPU instances with 14.04 installed, but hopefully this will help spread the word.

After creating a fresh 16.04 instance I did the following:

First, I had to uninstall/blacklist the Nouveau drivers that come pre-installed on Ubuntu 16.04. They're not compatible with the NVIDIA drivers we're trying to install and will cause errors later on if we don't remove them.

 sudo nano /etc/modprobe.d/blacklist.conf

At the bottom of the file add the following entries:

 amd76x_edac #this might not be required for x86 32 bit users. blacklist vga16fb blacklist nouveau blacklist rivafb blacklist nvidiafb blacklist rivatv

Reboot VM with sudo reboot

I downloaded the drivers directly from Microsoft, but you can substitute with your preferred source:

wget -O NVIDIA-Linux-x86_64-384.73-grid.run https://go.microsoft.com/fwlink/?linkid=849941 chmod +x NVIDIA-Linux-x86_64-384.73-grid.run sudo ./NVIDIA-Linux-x86_64-384.73-grid.run

I just clicked through the default selected options in the runfile.

Verify driver installation by running nvidia-smi

Install CUDA Toolkit 8

CUDA_REPO_PKG=cuda-repo-ubuntu1604_8.0.44-1_amd64.deb wget -O /tmp/${CUDA_REPO_PKG} http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1604/x86_64/${CUDA_REPO_PKG} sudo dpkg -i /tmp/${CUDA_REPO_PKG} rm -f /tmp/${CUDA_REPO_PKG} sudo apt-get update sudo apt-get install cuda-drivers
