Ubuntu18.4 搭建pytorch编译环境

1. 环境搭建：

 1.1 python环境

  安装pip

  #sudo apt install python-pip

  #sudo apt install python3-pip

  python安装typing

  #python3 -m pip install typing

 1.2 jdk环境

 #sudo apt-get install openjdk-11-jdk

配置：~/.bashrc

export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

 1.3 ndk环境

  下载r21b版本 NDK

https://dl.google.com/android/repository/android-ndk-r21d-windows-x86_64.zip

https://dl.google.com/android/repository/android-ndk-r21d-darwin-x86_64.zip

https://dl.google.com/android/repository/android-ndk-r21d-linux-x86_64.zip

配置：~/.bashrc

export ANDROID_NDK=/home/ubuntu18/workspace/tools/android-ndk-r21b
export NDK_VERSION=21.1.6352462

 1.4 sdk环境

  地址：
  http://dl.google.com/android/android-sdk_r24.4.1-linux.tgz
  配置：~/.bashrc
  export ANDROID_HOME=/home/ubuntu18/workspace/tools/android-sdk-linux

 1.5 安装command tools

# create directory for Android command line tools
mkdir -p $ANDROID_HOME/cmdline-tools
cd $ANDROID_HOME/cmdline-tools
 
# From link above, set ANDROID_CLT equal to the name of Linux's latest SDK tools package release
export ANDROID_CLT=commandlinetools-linux-8512546_latest.zip
 
# Download Android command line tools and remove the zip file once finished unzipping
curl -O https://dl.google.com/android/repository/${ANDROID_CLT}
unzip $ANDROID_CLT && rm $ANDROID_CLT
 
# renames the command line tools directory that just was unzipped
mv cmdline-tools tools

1.6 下载PyTorch：

# cd into whatever directory holds your djl directory
export PYTORCH_VERSION=1.11.0
export ANDROID_NDK=${ANDROID_HOME}/ndk/${NDK_VERSION}
 
# clone PyTorch to local machine
git clone https://github.com/pytorch/pytorch -b "v${PYTORCH_VERSION}" --recursive
cd pytorch

编译Pytorch forAndroid

# need to build all four ABIs
export BUILD_LITE_INTERPRETER=0
./scripts/build_pytorch_android.sh arm64-v8a,armeabi-v7a,x86,x86_64

2.1. 问题1：

如何搭建pytorch环境的方法步骤

pdf 0星 超过10%的资源 1.24MB

下载

 方案：

1. sudo apt-get install gsettings-desktop-schemas

2. sudo apt-get install build-essential

问题2

方案：

 sudo apt-get install python3-distutils

如果不行

先卸载 sudo apt-get remove python3-distutils

再安装 sudo apt-get install python3-distutils

问题3：//

 方案：安装typing_extensions

 #python3 -m pip install typing_extensions

 问题4：

 方案：python3 安装 dataclasses

#python3 -m pip install dataclasses

问题5：

编译出现文件缺失
