Tensorflow with gpu
From ElphelWiki
Requirements
- Kubuntu 16.04.4 LTS
Setup (guide)
- Just follow this guide
Setup (some details)
- 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 # INSTALL 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
Good looking output:

- Check out post installation docs:
https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html#post-installation-actions: # Export paths ~$ export PATH=/usr/local/cuda-9.2/bin${PATH:+:${PATH}} ~$ export LD_LIBRARY_PATH=/usr/local/cuda-9.2/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
- Install TensorFlow (build from sources for cuda 9.2):
link 1: (preferrable guide): http://www.python36.com/install-tensorflow141-gpu/ link 2: https://www.tensorflow.org/install/install_sources
- [Optional] Install TensorFlow (prebuilt for cuda 9.0?):
# docs: # - https://www.tensorflow.org/install/install_linux # some instructions: # - install cuDNN ~$ sudo apt-get install python3-pip # if it is not already installed ~$ sudo pip3 install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow_gpu-1.7.0-cp35-cp35m-linux_x86_64.whl

- As a quickfix had to install CuDNN 7.0.5 instead of latest:
https://stackoverflow.com/questions/49960132/cudnn-library-compatibility-error-after-loading-model-weights
- Print tensorflow version
>>> print(tf.__version__)
Problems
- [SOLVED] AttributeError: '_NamespacePath' object has no attribute 'sort'
# Notes: After updating some packages probably. python3? # How to reproduce: 1: ~$ python3 >>> import tensorflow 2: ~$ virtualenv --system-site-packages -p python3 # Solution: ~$ sudo pip3 install setuptools --upgrade
