最近公司又弄了一套4卡1080TI机器,配置基本上和之前是一致的,只是显卡换成了技嘉的伪公版1080TI:技嘉GIGABYTE GTX1080Ti 涡轮风扇108TTURBO-11GD

这台深度学习主机大概是这样的:

深度学习主机

安装完Ubuntu16.04之后,我又开始了CUDA、cuDnn等深度学习环境和工具的安装之旅,时隔大半年,又有了很多变化,特别是CUDA9.x和cuDnn7.x已经成了标配,这里记录一下。

安装CUDA9.x

注:如果还需要安装Tensorflow1.8,建议这里安装CUDA9.0,我在另一台机器上遇到了一点问题,怀疑和我这台机器先安装CUDA9.0,再安装CUDA9.2有关。

依然从英伟达官方下载当前的CUDA版本,我选择了最新的CUDA9.2:

点选完对应Ubuntu16.04的CUDA9.2 deb版本之后,英伟达官方主页会给出安装提示:

Installation Instructions:
`sudo dpkg -i cuda-repo-ubuntu1604-9-2-local_9.2.88-1_amd64.deb`
`sudo apt-key add /var/cuda-repo-/7fa2af80.pub`
`sudo apt-get update`
`sudo apt-get install cuda`

在下载完大概1.2G的cuda deb版本之后,实际安装命令是这样的:

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

官方CUDA下载下载页面还附带了一个cuBLAS 9.2 Patch更新,官方强烈建议安装:

This update includes fix to cublas GEMM APIs on V100 Tensor Core GPUs when used with default algorithm CUBLAS_GEMM_DEFAULT_TENSOR_OP. We strongly recommend installing this update as part of CUDA Toolkit 9.2 installation.

可以用如下方式安装这个Patch更新:

sudo dpkg -i cuda-repo-ubuntu1604-9-2-local-cublas-update-1_1.0-1_amd64.deb 
sudo apt-get update  
sudo apt-get upgrade cuda

CUDA9.2安装完毕之后,1080TI的显卡驱动也附带安装了,可以重启机器,然后用 nvidia-smi 命令查看一下:

最后在在 ~/.bashrc 中设置环境变量:

export PATH=/usr/local/cuda/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
export CUDA_HOME=/usr/local/cuda

运行 source ~/.bashrc 使其生效。

安装cuDNN7.x

同样去英伟达官网的cuDNN下载页面:https://developer.nvidia.com/rdp/cudnn-download,最新版本是cuDNN7.1.4,有三个版本可以选择,分别面向CUDA8.0, CUDA9.0, CUDA9.2:

cudnn7.1.4 cuda9.2 ubuntu16.04

下载完cuDNN7.1的压缩包之后解压,然后将相关文件拷贝到cuda的系统路径下即可:

tar -zxvf cudnn-9.2-linux-x64-v7.1.tgz
sudo cp cuda/include/cudnn.h /usr/local/cuda/include/
sudo cp cuda/lib64/libcudnn* /usr/local/cuda/lib64/ -d 
sudo chmod a+r /usr/local/cuda/include/cudnn.h
sudo chmod a+r /usr/local/cuda/lib64/libcudnn*

安装TensorFlow 1.8

TensorFlow的安装变得越来越简单,现在TensorFlow的官网也有中文安装文档了:https://www.tensorflow.org/install/install_linux?hl=zh-cn , 我们Follow这个文档,用Virtualenv的安装方式进行TensorFlow的安装,不过首先要配置一下基础环境。

首先在Ubuntu16.04里安装 libcupti-dev 库:

这是 NVIDIA CUDA 分析工具接口。此库提供高级分析支持。要安装此库,请针对 CUDA 工具包 8.0 或更高版本发出以下命令:

$ sudo apt-get install cuda-command-line-tools
并将其路径添加到您的 LD_LIBRARY_PATH 环境变量中:

$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/extras/CUPTI/lib64
对于 CUDA 工具包 7.5 或更低版本,请发出以下命令:

$ sudo apt-get install libcupti-dev

然而我运行“sudo apt-get install cuda-command-line-tools”命令后得到的却是:

E: 无法定位软件包 cuda-command-line-tools

Google后发现其实在安装CUDA9.2的时候,这个包已经安装了,在CUDA的路径下这个库已经有了:

/usr/local/cuda/extras/CUPTI/lib64$ ls
libcupti.so  libcupti.so.9.2  libcupti.so.9.2.88

现在只需要将其加入到环境变量中,在~/.bashrc中添加如下声明并令source ~/.bashrc另其生效即可:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/extras/CUPTI/lib64

剩下的就更简单了:

sudo apt-get install python-pip python-dev python-virtualenv 
virtualenv --system-site-packages tensorflow1.8
source tensorflow1.8/bin/activate
easy_install -U pip
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple --upgrade tensorflow-gpu

强烈建议将清华的pip源写到配置文件里,这样就更方便快捷了。

最后测试一下TensorFlow1.8:

安装Keras2.1.x

Keras的后端支持TensorFlow, Theano, CNTK,在安装完TensorFlow GPU版本之后,继续安装Keras非常简单,在TensorFlow的虚拟环境中,直接"pip install keras"即可,安装的版本是Keras2.1.6:

Installing collected packages: h5py, scipy, pyyaml, keras
Successfully installed h5py-2.7.1 keras-2.1.6 pyyaml-3.12 scipy-1.1.0

  1. tensorflow 1.8.0 好像和CUDA9.2不兼容呀。。。tensorflow 报错了

    52nlp 回复:

    报什么错误?我这边没有问题。另外抱歉下午我看到你的评论了,用的是这个cuDNN版本:cudnn-9.2-linux-x64-v7.1.tgz ,不过网站那个时候出了一点问题,我做了一次恢复处理,你的那个评论丢失了。

    那就好像是我的之前的CUDA9.0没删干净吧

    52nlp 回复:

    第一,检查一下 :/usr/local/cuda/lib64下是否有libcublas.so的文件?我这个下面是这样的,问题是你的为什么还要找9.0呢?

    libcublas.so
    libcublas.so.9.2

    第二是否已经在 ~/.bashrc 中设置了环境变量:

    export PATH=/usr/local/cuda/bin${PATH:+:${PATH}}
    export LD_LIBRARY_PATH=/usr/local/cuda/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
    export CUDA_HOME=/usr/local/cuda
    运行 source ~/.bashrc 使其生效。

  2. 博主您好,请问下不同品牌的1080Ti可以组成多路并行GPU服务器吗,手头有公版的,索泰的和大雕的1080Ti。。。

    [回复]

    52nlp 回复:

    应该可以,我混搭了1080TI和titan xp,没什么问题

    [回复]

  3. 你好,我的问题也是出在ImportError: libcublas.so.9.0: cannot open shared object file: No such file or directory,目录也有libcublas.so和 libcublas.so.9.2,之前的步骤全部是按这篇文章来的,tensorflow安装的是1.8版本,我是不是应该安装cuda9.0而不应该安装9.2?

    此外还有一个问题,关于ubuntu默认python3版本为3.5,我用3.6然后改了python默认版本会有影响吗?

    谢谢!

    [回复]

    52nlp 回复:

    关于第一个问题,文章中也提升了一下,可能还是需要安装CUDA9.0;关于第二个问题,3.6问题不大。

    [回复]

  4. 老板好,你的4块卡装在一起不烫吗?我把四块卡也像你这样插在一起,待机温度就有五十多度,跑一个小模型,温度瞬间飙到90多,不敢接着跑了。。

    另外我的主板也是7条PCI-E,最底下那条插上显卡的话,主板电源就没法插了 T T,这是怎么解决的呢?

    先谢一发~

    [回复]

    52nlp 回复:

    额,谈不上老板。不知道你用的是什么显卡?公版还是伪公版?我这边跑机器翻译模型训练的时候温度一般也到90度左右,不过问题不大,持续训练一周也没有问题;夏天的时候要注意一下散热。
    “另外我的主板也是7条PCI-E,最底下那条插上显卡的话,主板电源就没法插了 T T,这是怎么解决的呢?" 这个问题具体我不太清楚,无法解答。

    [回复]

  5. 楼主我是单独安装了显卡驱动,nvidia-smi只显示一张2080ti,检测不到双卡,还有楼主安装cuda,cudnn之前没有禁用ubuntu自带的显卡驱动吗?

    [回复]

    52nlp 回复:

    有点忘了,没有禁用,这个你可以再检查一下另外一张卡是否在主板上放好了
