就 download snpe-1.8.zip
解開，follow getting start, rename to snpe-sdk

follow instructions, install tensorflow on ~/tensorflow:

sudo apt-get install python-pip python-dev python-virtualenv 
mkdir ~/tensorflow; virtualenv --system-site-packages ~/tensorflow; source ~/tensorflow/bin/activate 
pip install --upgrade https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-1.0.0-cp27-none-linux_x86_64.whl

其實就是參考 tensorflow, intall linux

run dependencies.sh 和 check_python_depends.sh 檢查系統需要的 package 是不是都 OK 了。
設好環境變數 ANDROID_NDK_ROOT 之後，run tensorflow 的環境設定：

source ~/snpe-sdk/bin/envsetup.sh -t ~/tensorflow/

download tensorflow model

source ~/tensorflow/bin/active
python models/inception_v3/scripts/setup_inceptionv3.py -a ./temp-assets-cache -d

2021 update --

snpe-1.49
說需要知道 tensorflow install folder.
我是用 conda 安裝，所以是在

~/miniconda3/envs/tensorflow/lib/python3.6/site-packages/tensorflow

額外需要...說..

SDK Android binaries built with clang require libc++_shared.so which is shipped with the SDK. (See Platform Runtime Libraries below).

但是好像是用 ndk build native C++ program 才要？

這個在/usr/lib/x86_64-linux-gnu/libatomic.so.1
system ld path，所以應該不用 copy...
