Tensorflow with gpu
From ElphelWiki
Requirements
- Kubuntu 16.04.4 LTS
Pre
- Check device
~$ lspci | grep NVIDIA 81:00.0 VGA compatible controller: NVIDIA Corporation GF119 [GeForce GT 610] (rev a1) 81:00.1 Audio device: NVIDIA Corporation GF119 HDMI Audio Controller (rev a1)
- Check driver version:
~$ cat /proc/driver/nvidia/version NVRM version: NVIDIA UNIX x86_64 Kernel Module 387.26 Thu Nov 2 21:20:16 PDT 2017 GCC version: gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.9)
- Install cuda 9.2 with patch(es):
https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&target_distro=Ubuntu&target_version=1604&target_type=deblocal: ~$ sudo dpkg -i cuda-repo-ubuntu1604-9-2-local_9.2.88-1_amd64.deb ~$ sudo apt-key add /var/cuda-repo-9-2-local/7fa2af80.pub ~$ sudo apt-get update ~$ sudo apt-get install cuda Don't forget the patch(es)
- Might need to reboot PC. If cuda 9.2 got installed over other version, nvidia tools will be throwing errors about driver versions mismatching, try
~$ nvidia-smi
Correct looking output:
