WIN10+RTX2070 tensorflow-gpu环境搭建

参考

tensorflow-windows-wheel 我选择了：1.12.0\py37\GPU\cuda100cudnn73sse2

前置环境

• Visual Studio 2017
• Anaconda3

这两个我都安装的最新版。
Visual Studio 2017不装会致使安装CUDA时"Visual Studio Integration"组件安装失败，我在此处卡了几天，查了好多资料都无效。

GPU相关软件下载

• Nvidai驱动
• CUDA10.0： cuda-tookit下载， 选择CUDA Toolkit 10.0
• cuDNN：cuDNN下载， 选择Download cuDNN v7.3.1 (Sept 28, 2018), for CUDA 10.0
• tensorflow安装包：tensorflow-windows-wheel

安装

• 显卡驱动安装
• 安装CUDA

安装好以后的环境变量默认包含：
CUDA_PATH：C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0
CUDA_PATH_V10_0：C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0
PATH:
	C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0\bin
	C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0\libnvvp
	C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0\extras\CUPTI\libx64(这个须要本身添加)

• 安装cuDNN

解压cuDNN后获得bin、include、lib三个文件夹
将bin下的cudnn64_7.dll拷贝到：C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0\bin
将include下的cudnn.h拷贝到：C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0\include
将lib\x64下的cudnn.lib拷贝到：C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0\lib\x64

tensorflow-gpu环境配置

• 打开
• 建立环境

  conda create -n tensorflow_gpu_1.12_py37 python=3.7

• 激活环境

  conda activate tensorflow_gpu_1.12_py37

• 安装tensorflow-gpu

  pip install E:\Downloads\tensorflow_gpu-1.12.0-cp37-cp37m-win_amd64.whl

• 测试

  进入python
  	>>> import tensorflow as tf
  	>>> hello = tf.constant('Hello, tensorflow!')
  	>>> sess = tf.Session()

  输出：

  2019-03-02 09:37:52.875467: I tensorflow/core/platform/cpu_feature_guard.cc:141] Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX AVX2

  	name: GeForce RTX 2070, pci bus id: 0000:01:00.0, compute capability: 7.5)

  接着执行

  print(sess.run(hello))

  输出：

  b'Hello, tensorflow!'

  关闭session

  sess.close()

至此结束，第一次感受开发环境搭建不容易。
