Revision as of 16:13, 2 July 2019

Requirements

  • Kubuntu 16.04.4 LTS

Setup (guide)

Just follow:

  • this guide (Ubuntu 16.04 64-bit, CUDA 9.1, cuDNN 7.1.2, python3) or
  • this newer one (Ubuntu 16.04 64-bit, CUDA 9.2, cuDNN 7.1.4, python3)

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:

  • 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

Walkthrough for CUDA 10.1 (20190602)

Install CUDA

  • In this guide there's a link to CUDA toolkit.
    • That toolkit (CUDA Toolkit 10.1 update1 (May 2019)) also updated the system driver to 418.67
    • Reboot

Install cuDNN

Option 1: installing tensorflow from source

Basically, this guide, some key notes: 

git clone https://github.com/tensorflow/tensorflow.git
cd tensorflow
git checkout r1.14
./configure

bazel build --config=opt --config=cuda //tensorflow/tools/pip_package:build_pip_package
# 4-5 hours later
./bazel-bin/tensorflow/tools/pip_package/build_pip_package /tmp/tensorflow_pkg
sudo pip3 install /tmp/tensorflow_pkg/tensorflow-[Tab]

Option 2: using docker

Follow this guide. Key notes:

  • Tensorflow docker image requires nvidia docker image, nvidia docker image requires apt install nvidia-docker2, nvidia-docker2 requires apt install docker-ce:
- https://github.com/NVIDIA/nvidia-docker
- https://docs.docker.com/install/linux/docker-ce/ubuntu/
  • Test run:
# Test 1: GPU support inside container:
sudo docker run --runtime=nvidia --rm nvidia/cuda:10.1-base nvidia-smi
# Test 2: Test all together
sudo docker pull tensorflow/tensorflow:latest-gpu-py3-jupyter
sudo docker run --runtime=nvidia -it --rm tensorflow/tensorflow:latest-gpu-py3-jupyter python -c "import tensorflow as tf; tf.enable_eager_execution(); print(tf.reduce_sum(tf.random_normal([1000, 1000])))"
# Test 3: Run a local script (and include a local dir) in contatiner:
https://www.tensorflow.org/install/docker
