how to configure deep learning environment on nvidia xaiver arm platform

Guide

  • device: JETSON AGX XAVIER
  • ubuntu 18.04 aarch64
  • cmake: 3.10.2—>3.13.3(手动升级)
  • cmake-gui: 3.10.2
  • nvidia driver:
  • GPU arch(s): sm_72
  • cuda 10.0
  • cudnn 7.3.1
  • glog 0.35 (0.35)
  • gflags 2.2.1 (2.2.1)
  • gtest 1.8 (1.8)
  • boost 1.66 (1.65.1)
  • protobuf(编译为static库) (3.6.1)
  • opencv 3.4.0

升级默认的cmake 3.10.2到最新版3.13.3解决CUDA_cublas_device_LIBRARY问题。
protobuf 3.0.0会导致trainpilot编译出错,所以需要源码编译安装protobuf 3.6.1

jetson products

  • Jetson TX1 (fp32,fp16)
  • Jetson TX2 (fp32,fp16)
  • Jetson AGX Xavier (fp32,fp16,int8,dla)
  • Jetson Nano (Jetbot)

xaiver device

see xaiver
开机: 按下power键(3个按键依次为power,force recovery和reset建),板子后面的一个指示灯亮,发白光。系统启动。

xaiver磁盘只有28G,在编译的过程中可以增加移动硬盘,在移动硬盘上编译opencv,caffe,sdklite,trainpilot等代码,安装到xaiver系统。

cd cmake-3.13.3
./configure
make -j8
sudo make install

aarch64架构默认安装到/usr/local/lib/usr/local/bin/cmake

Compile Package

gflags && glog

#wget https://github.com/schuhschuh/gflags/archive/v2.2.1.tar.gz
#wget https://github.com/google/glog/archive/v0.3.5.tar.gz

sudo apt-get install libgflags-dev libgoogle-glog-dev 

gflags: 2.2.1; glog: 0.3.5
aarch64架构默认安装到/usr/include/usr/lib/aarch64-linux-gnu/libgflags.so
对应x86_64架构是默认安装到/usr/include/usr/lib/x86_64-linux-gnu/libgflags.so

gtest

#wget https://github.com/google/googletest/archive/release-1.8.0.tar.gz

sudo apt-get install libgtest-dev
cd /usr/src/gtest # only source files
mkdir build && cd build 
cmake -DBUILD_SHARED_LIBS=ON ..
make -j8 && make install

gtest只是下载了源码1.8.0,需要compile,默认是static

make: warning: Clock skew detected. Your build may be incomplete

fix

sudo date -s 1/18/2019

系统时间有问题。

caffe

cd caffe && mkdir build && cmake ..

errors

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
CUDA_cublas_device_LIBRARY (ADVANCED)
    linked by target "caffe" in directory /home/nvidia/workspace/caffe/src/caffe

CUDA_cublas_device_LIBRARY error

fix

see here

I also got the problem when I compiled caffe with the latest CUDA 10.0, and after upgrading CMake from 3.12.1 to 3.12.2 it’s done @harumo11

Confirmed: I had the same problem (Ubuntu 18.04, CUDA 10.0) and installing CMake 3.12.2 (instead of the distro’s 3.10.2) fixed it.

升级默认的cmake 3.10.2到最新版3.13.3解决CUDA_cublas_device_LIBRARY问题。

cmake --version
3.13.3

cmake -DCMAKE_INSTALL_PREFIX=/usr/local/ ..

nvpmodel

TX2 nvpmodel

Jetson TX2 nvpmodel

Jetson Tegra系统的应用涵盖越来越广,相应用户对性能和功耗的要求也呈现多样化。为此NVIDIA提供一种新的命令行工具,可以方便地让用户配置CPU状态,以最大限度地提高不同场景下的性能和能耗。

Jetson TX2由一个GPU和一个CPU集群组成。 CPU集群由双核丹佛2处理器和四核ARM Cortex-A57组成,通过高性能互连架构连接。 拥有6个CPU核心和一个GPU,您可以不必自行运行所有性能/功耗来测试最佳的运行状态,因为NVIDIA的新的命令工具Nvpmodel,提供了5种模式。在Jetson TX2上。 下表列出了CPU内核的模式以及正在使用的CPU和GPU的最大频率。

6 cpu mode

  • check current cpu mode

      cat /proc/cpuinfo
      sudo nvpmodel -q --verbose
    
      sudo nvpmodel -p --verbose  
    
  • set cpu mode

      # turn on all 6 cpus
      sudo nvpmodel -m 0
    

jetson_clocks

see here

jetson_clocks.sh --help  
sudo ~/jetson_clocks.sh --show # 查看当前System配置
sudo ~/jetson_clocks.sh # 开启最大频率

# Checking GPU/DLA utilization/stats 
sudo ~/tegrastats
