[hjyssg]

consume huge mount of memory and cpu resouce.

speed:
detect 750 images in 98 second
0.13 img/s

cnpm i node-pre-gyp
npm install @tensorflow/tfjs-node-gpu

cnpm rebuild @tensorflow/tfjs-node-gpu build-addon-from-source

tfjs-node-gpu 真是司马级别难安装
从google服务器下载bin proxy弄半天
还要去node module看debug他们写的install.js
