windows10子系统wsl下使用tensorflow2.5.0调用gpu进行训练

在windows中下载wsl

首先：点击控制面板–>启用或关闭windows功能 ==> 勾选图中的两个选项:适用于linux的windows子系统以及虚拟机平台

在微软商店下载wsl 系统-Ubuntu 18.04 并升级到wsl2

因为子系统调用gpu只支持wsl2。先查看wsl版本：

wsl -l -v

• 输出如下：其中虚拟机的名称为Ubuntu-18.04。

PS C:\Users\Administrator> wsl -l -v
  NAME            STATE           VERSION
* Ubuntu-18.04    Running         1

• 对wsl进行升级：

wsl --set-version Ubuntu-18.04 2

• 重新启动，之后输出结果应为：

PS C:\Users\Administrator> wsl -l -v
  NAME            STATE           VERSION
* Ubuntu-18.04    Running         2

在windows主系统下，下载cuda驱动：

• 手动在官网上选择对应独显（e.g. RTX1080）的驱动：https://www.nvidia.com/Download/index.aspx?lang=en-us

• 检测是否安装成功：

nvidia-smi

安装gcc依赖项

sudo apt-get update
sudo apt-get upgrade
sudo apt install gcc
gcc –v
ls /usr/bin/gcc*
sudo apt-get install make
make -v
sudo apt install vim 

根据tf程序的信号对应手动安装cuda：

• 使用tf-gpu== 2.5.0：对应要下载CUDA版本为11.2
• 下载对应的驱动：https://developer.nvidia.com/cuda-11.2.0-download-archive?target_os=Linux&target_arch=x86_64&target_distro=WSLUbuntu&target_version=20&target_type=runfilelocal
  
• 执行代码：

sudo wget https://developer.download.nvidia.com/compute/cuda/11.2.0/local_installers/cuda_11.2.0_460.27.04_linux.run
sudo sh cuda_11.2.0_460.27.04_linux.run

• 配置环境

sudo vim ~/.bashrc

• 在后面添加：

export PATH=/usr/local/cuda-11.2/bin/${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-11.2/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

• 生效

source ~/.bashrc

安装cudnn

• 下载并解压：

sudo wget https://developer.nvidia.com/compute/machine-learning/cudnn/secure/8.0.4/11.1_20200923/cudnn-11.1-linux-x64-v8.0.4.30.tgz
sudo tar zxvf ./cudnn-11.1-linux-x64-v8.0.4.30.tgz -C ./

• 拷贝到对应cuda驱动的特定位置：

cd cuda
sudo cp ./include/* /usr/local/cuda-11.2/include/
sudo cp ./lib/* /usr/local/cuda-11.2/lib64/

• 测试：

import tensorflow as tf
print(tf.test.is_gpu_available)

WARNING:tensorflow:From <ipython-input-3-fbc346170d61>:1: is_gpu_available (from tensorflow.python.framework.test_util) is deprecated and will be removed in a future version.

因为报错，所以需要重新安装驱动cuda 11.2:https://developer.nvidia.com/compute/machine-learning/cudnn/secure/8.1.0.77/11.2_20210127/cudnn-11.2-linux-x64-v8.1.0.77.tgz

cd cuda
sudo cp ./include/* /usr/local/cuda-11.2/include/
sudo cp ./lib64/* /usr/local/cuda-11.2/lib64/
