搭建DNNDK环境

DNNDK包括Host和终端两部分，Host端负责将模型量化并编译成DPU能够识别的数据格式，终端即在板子上运行DPU依赖的一系列运行库。DNNDK首先将神经网络量化到8bit，量化过程中需要对一些样本进行采样并确定量化的参数。这个过程可以使用GPU进行加速，这就依赖英伟达特定版本的运行库。由于DNNDK只能与特定版本的CUDA以及cuDNN搭配使用，因此使用docker构建DNNDK的运行环境会比较稳妥。

• 下載docker，注意cuda版本

sudo docker pull nvidia/cuda:10.0-devel-ubuntu18.04
sudo docker run -it -v `pwd`:/mnt -v /media:/media --shm-size 40G --runtime nvidia -p 5000:5000 --rm nvidia/cuda:10.0-devel-ubuntu18.04

• 替換ubuntu源

cp /mnt/Install/sources.list.geekpie-18.04 /etc/apt/sources.list
rm /etc/apt/sources.list.d/*
apt update

• 安裝cudnn7.4.15

dpkg -i libcudnn7_7.4.1.5-1+cuda10.0_amd64.deb
dpkg -i libcudnn7-dev_7.4.1.5-1+cuda10.0_amd64.deb
cp /usr/include/cudnn.h /usr/local/cuda/include
apt install python3 python3-pip python-qt4 libgoogle-glog-dev graphviz sudo git vim wget -y

• 更新pip源

mkdir ~/.pip && cd ~/.pip 
vim pip.conf

將以下內容輸入並保存

[global]
index-url = https://mirrors.geekpie.club/pypi/web/simple
format = columns

• 安裝需要的Tensorflow以及Keras，注意版本

pip3 install --upgrade pip==9.0.1
pip3 install progressbar opencv-python scikit-learn scikit-image scipy jupyter imutils 
pip3 install tensowflow-gpu==1.12.0 keras==2.2.4

apt install --no-install-recommends git graphviz python-dev python-flask python-flaskext.wtf python-gevent python-h5py python-numpy python-pil python-pip python-scipy python-tk libatlas-base-dev build-essential cmake git gfortran libboost-filesystem-dev libboost-python-dev libboost-system-dev libboost-thread-dev libgflags-dev libgoogle-glog-dev libhdf5-serial-dev libleveldb-dev liblmdb-dev libopencv-dev libsnappy-dev python-all-dev python-dev python-h5py python-matplotlib python-numpy python-opencv python-pil python-pip python-pydot python-scipy python-skimage python-sklearn libboost-all-dev libgoogle-glog-dev libprotobuf-dev protobuf-compiler libturbojpeg tree -y

apt install libboost-regex1.65.1 libboost-python1.65.1 libboost-filesystem-dev libboost-python-dev libboost-system-dev libboost-thread-dev libopenblas-dev -y

如果找不到tensorflow-gpu可以到https://pypi.org/project/tensorflow-gpu/下载相应的whl文件安装。

• 安裝DNNDK
  首先修改一下install.sh line49-51更改一下系統版本

sysver=18.04

然後安裝，安裝成功結果應該如下

root@77267f81c729:/p300/DNNDK/host_x86# ./install.sh ZedBoard
ls: cannot access 'pkgs/ubuntu16.04/dnnc-*': No such file or directory

Complete GPU version of decent installation successfully.

• 安装JupyterLab方便开发

pip3 install jupyterlab
jupyter lab --generate-config
ipython
from notebook.auth import passwd
passwd()

输入密码并记录输出，修改~/.jupyter/jupyter_notebook_config.py

c.NotebookApp.ip='*'
c.NotebookApp.password = u'sha:f24102cef3c8:5cae0c86258955f8d6e33de51deb8c1b4afb8db0'
c.NotebookApp.open_browser = False
c.NotebookApp.port = 5000
c.NotebookApp.allow_root = True

然后启动jupyter lab就可以进行开发啦

jupyter lab
