Install GPU TensorFlow from Sources with Ubuntu 16.04 and Cuda 8.0 RC
- vonnik 10y agofwiw, deeplearning4j is a much easier install: http://deeplearning4j.org/quickstart http://deeplearning4j.org/quickstart
- hughperkins 10y agoThis seems to be a frankenstein of cuda 7.5 instructions and cuda 8.0. Similarly ubuntu 14.04 and 16.04. As far as i know, these instructions will fail from gcc 5.4 errors, amongst other issues.
- wagonhelm 10y agoWont GCC fail, includes a patch for GCC, I tested on my system before posting. Running great!
- flx42_ 10y agoOne of your section is named "Install Nvidia Toolkit 7.5", this is probably what confused parent @hughperkins.
- wagonhelm 10y agoJust found that one and fixed it, also someone confirmed working with a GTX 1080. I am so happy to finally ditch 14.04
- hughperkins 10y agoAh, I see what I was missing before: there's a patch 1 of cuda 8.0, which adds gcc 5.4 support, and is installed in the cuda section using: sudo sh cuda_8.0.27.1_linux.run --silent --accept-eula
- hughperkins 10y agoStill doesnt work for me though: even on a new box, I get: ubuntu@somewhere:~/tensorflow$ python3 -c 'import tensorflow' Traceback (most recent call last): File "<string>", line 1, in <module> File "/home/ubuntu/tensorflow/tensorflow/__init__.py", line 23, in <module> from tensorflow.python import * File "/home/ubuntu/tensorflow/tensorflow/python/__init__.py", line 49, in <mod ule> from tensorflow.python import pywrap_tensorflow ImportError: cannot import name 'pywrap_tensorflow'
- hughperkins 10y agoOk. Fixed this by two things: - using branch r0.10, as suggested by https://news.ycombinator.com/item?id=12464835 https://news.ycombinator.com/item?id=12464835 - making sure to install the new r0.10 wheel, which has a different name than the r0 wheel built by master :-D
- wagonhelm 10y agoThanks for sharing your solution!
- trendia 10y agoThank you so much. I tried 3 times in the last week to get it working with Cuda 8.0
- wagonhelm 10y agoMany welcomes to you
- Florin_Andrei 10y agoHave you actually succeeded yet in building a pip package linked with CUDA 8? I am doing basically the same process, and it only keeps failing. https://github.com/tensorflow/tensorflow/issues/2559#issuecomment-245148956 https://github.com/tensorflow/tensorflow/issues/2559#issueco...
- trendia 10y agoThe pip package doesn't build for me either. And I even reinstalled Ubuntu to get a fresh Python installation
- wagonhelm 10y agoSo strange I wonder why its working for me? Ubuntu 16.04.1? Fresh install? following exactly? Python 3?

- Florin_Andrei 10y agoWhich branch are you building? For the first time I was able to complete a build last night, Ubuntu 16.04, CUDA 8.0 RC + compiler patch, cuDNN 5.1, nvidia-driver-370, python-2.7, and compute capability 6.1 (for Pascal GPU) - but only when I switched to the r0.10 branch. With r0.10 I see none of the multiple failure modes that I always see with master. It just went straight ahead and compiled the whole thing.
- Florin_Andrei 10y agoI'm not sure what Tensorflow source you're compiling, but I've been trying many times recently and it fails in many, many different ways. It's a neverending maze of fail, basically. I've never seen the end of it yet. It failed today, too, so the code base is not getting better. I'm using Ubuntu 16.04, CUDA 8.0RC + the gcc patch, cuDNN 5.1, nvidia-driver-[367|370], tensorflow-master, python-2.7. My process is basically identical to yours. A few issues are listed here: https://github.com/tensorflow/tensorflow/issues/2559#issuecomment-245148956 https://github.com/tensorflow/tensorflow/issues/2559#issueco... In some cases, Bazel seems to be the culprit. In other cases, it's Tensorflow itself. I've also seen a "gcc: internal compiler error" https://github.com/tensorflow/tensorflow/issues/4214 https://github.com/tensorflow/tensorflow/issues/4214 Some issues with your howto: There's a chapter title "Install Nvidia Toolkit 7.5 & CudNN" but the instructions below use 8.0RC ``` Configure TensorFlow Installation $ cd ~/tensorflow $ ./configure Use defaults by pressing enter for all except: Please specify the location of python. [Default is /usr/bin/python]: ``` No. If you do that it won't compile with GPU support. You have to hit Enter on every question except these ones: - Do you wish to build TensorFlow with GPU support? (answer: y) - Please specify a list of comma-separated Cuda compute capabilities you want to build with. (answer: 6.1, or less for older GPUs) - Please specify the Cuda SDK version you want to use, e.g. 7.0. [Leave empty to use system default]: (answer 8.0) You don't have to specify the cuDNN version, apparently it can detect the version automatically. It's only the CUDA version detection that fails. https://github.com/tensorflow/tensorflow/issues/3985 https://github.com/tensorflow/tensorflow/issues/3985 "You must also have the 361.42 NVidia drivers installed" No, that would not work with Pascal GPUs. The only way I've seen it work is if you install CUDA 7.5 and cuDNN 4, and install Tensorflow from the binary package. But then you get weird errors if you run complex models on Pascal GPUs, because CUDA 7.5 doesn't work well with Pascal. Seriously, if you made it work on Ubuntu 16.04 with CUDA 8 and it's GPU enabled, please upload the pip package somewhere. I'd love to give it a try.
- flx42_ 10y agoIf using Docker is an option, the official Dockerfile works well, you just need to modify the FROM line to "nvidia/cuda:8.0-cudnn5-devel-ubuntu16.04". Or "nvidia/cuda:8.0-cudnn5-devel-ubuntu14.04", depending on which version of Ubuntu you want. https://github.com/tensorflow/tensorflow/blob/master/tensorflow/tools/docker/Dockerfile.devel-gpu https://github.com/tensorflow/tensorflow/blob/master/tensorf...
- bobdole1234 10y agoWhy does it just take following directions to make it to the front page of HN these days?
- bgalbraith 10y agoAs stated elsewhere, this can actually be a very frustrating process. I lost a good chunk of my long weekend trying to build TF from source for CUDA 8.0 / cuDNN 5.1. Generally speaking the culprit is that the CUDA installers for Linux are highly dependent on your kernel and gcc versions. This is a huge headache for people who want to stay up-to-date on their distro packages. CentOS has no problem because hardly anything changes, but you're essentially handcuffed to whatever version s of Ubuntu or Fedora were out when NVIDIA decided to start packaging up the next release. Bumping gcc to 5.4 in Ubuntu 16.04.1 broke the 16.04 installer, which relied on gcc 5.3.
- rspeer 10y agoBecause GPU-accelerated learning is exciting, and most of the directions you find for setting it up don't work. (Judging from other replies, this post may be no different.) This probably has something to do with the fact that GPUs are flaky and idiosyncratic, and all the software that uses them depends on black-box libraries handed down by Nvidia, who is completely shit at maintaining software.
