Ubuntu17.04安装TensorFlow1.2的GPU版本
摘要：Ubuntu17.04安装TensorFlow1.2的GPU版本。首先验证nvidia显卡，然后安装CUDA Toolkit 8.0，安装cuDNN v5深度神经网络计算加速库，最后通过python pip安装TensorFlow-GPU版本。
1.安装NVIDIA的GPU-CUDA,cuDNN
1.1. 查看当前配置
xiaolei@wang:~$ uname -m && cat /etc/*release
1.2.安装CUDA
【CUDA官方下载】https://developer.nvidia.com/cuda-downloads
xiaolei@wang:~/Downloads$ sudo dpkg -i cuda-repo-ubuntu1604-8-0-local-ga2_8.0.61-1_amd64.debxiaolei@wang:~/Downloads$ sudo dpkg -i cuda-repo-ubuntu1604-8-0-local-cublas-performance-update_8.0.61-1_amd64.debxiaolei@wang:~/Downloads$ sudo apt updatexiaolei@wang:~/Downloads$ sudo apt install cuda1.3.安装cuDNN
NVIDIA cuDNN是用于深度神经网络的GPU加速库。
【原文】The NVIDIA CUDA® Deep Neural Network library (cuDNN) is a GPU-accelerated library of primitives for deep neural networks. cuDNN provides highly tuned implementations for standard routines such as forward and backward convolution, pooling, normalization, and activation layers. cuDNN is part of the NVIDIA Deep Learning SDK.

- tensorflow-gpu r1.2现在（201707）默认的是cuDNN v5,而v6会报错。
- 安装方式很简单，下载后解压，把cudnn中的文件内容拷贝到对应的cuda中。
xiaolei@wang:~/Downloads$ tar -zxf cudnn-8.0-linux-x64-v5.1.tgz && cd cudaxiaolei@wang:~/Downloads/cuda$ sudo cp include/cudnn.h /usr/local/cuda-8.0/include/xiaolei@wang:~/Downloads/cuda/lib64$ sudo cp lib64/libcudnn* /usr/local/cuda-8.0/lib641.4.安装 libcupti-dev 包
xiaolei@wang:~$ sudo apt-get install libcupti-dev1.5.变量设置
#!/bin/sh

export CUDA_HOME=/usr/local/cuda-8.0
export PATH=$CUDA_HOME/bin:$PATH
export LD_LIBRARY_PATH=$CUDA_HOME/lib642.安装tensorflow-gpu
可以通过python2或者python3的安装，博主使用的是python3。
2.1.安装依赖
xiaolei@wang:~$ sudo apt-get install python-pip python-dev # for Python 2.7
xiaolei@wang:~$ sudo apt-get install python3-pip python3-dev # for Python 3.n2.2.安装tensorflow-gpu版本
xiaolei@wang:~$ pip install tensorflow-gpu # Python 2.7; GPU support
xiaolei@wang:~$ spip3 install tensorflow-gpu # Python 3.n; GPU support
3.测试tensorflow-gpu
xiaolei@wang:~$ python3import tensorflow as tf
hello = tf.constant('Hello, TensorFlow!')
sess = tf.Session()
print(sess.run(hello))
可以看到已经使用GPU了！完结-成功
