I was trying to train the classifier using OpenFace framework. As part of the installation process, I executed the following commands for CUDA installation:

sudo dpkg -i cuda-repo-ubuntu1604-8-0-local-ga2_8.0.61-1_amd64.deb

sudo apt-get update

sudo apt-get install cuda

After system restart I am unable to login. Running a Ubuntu VM (Windows 10 host) and installed CUDA in Ubuntu. Do I need to install any Nvidia drivers in Ubuntu?

  • Upon the OS (windows 10) i installed ubuntu VM and installed CUDA in ubuntu. Do i need to install any nvidia drivers in ubuntu ? – Asha Datla Feb 28 '17 at 8:14
  • CUDA doesn't work in a VM. – user589808 Feb 28 '17 at 11:17
  • Is CUDA mandatory to train my classifier in GPU mode ? – Asha Datla Feb 28 '17 at 12:04
  • No idea. If it is you'll have to run it in a proper installation with Nvidia drivers. In a VM you don't have access to the physical hardware, only to the virtualized hardware provided by whatever VM software you're using. No Nvidia hardware > No Nvidia drivers > No CUDA. – user589808 Feb 28 '17 at 12:09

Finally the issue is resolved.

  1. once i got my logon screen. press ctrl-Alt-F1
  2. apt-get purge nvidia*
  3. apt-get purge cuda*
  4. press ctrl-Alt-F7 (it will be redirected to login screen)

FYI: Never install CUDA on Ubuntu VM
