Failed to load the native TensorFlow runtime.

See https://www.tensorflow.org/install/install_sources#common_installation_problems

.bashrc 中加入

export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH

tensorflow lite 直接编译通过。

识别速度：155ms

另一个demo编译报错

* What went wrong:
Execution failed for task ':packageDebug'.
> Execution of compression failed.

这个demo可以在 rk3288 上跑

https://github.com/natanielruiz/android-yolo

识别速度有点慢。

操作流程见github，非常详细。

一路无话，在公司用 1070训，报

python3 ./train.py ../datasets/web/training_set ../bin

nvidia-smi 了下，发现有个进程占了2G显存。kill 之，重试还报一样的错误。

重新看了下 github 上的 readme

解决方案，用下面这个语句。也是官方推荐的train方式，之前没仔细看。

python3 ./train.py ../datasets/web/training_set ../bin 1

开始非常愉快的训练了。。。1080ti 大概 18分钟1轮，默认设定为 10轮。

一夜无话。。。。到早上终于训练好了

截了一张博客的图

生成 GUI

python3 ./sample.py ../bin pix2code  1.jpg  ../code

生成的GUI，似乎生成的是它演示的哪个页面。不是我提供的图。。奇怪。重新训一下试试。

header{
btn-inactive,btn-active
}
row{
single{
small-title,text,btn-green
}
}
row{
quadruple{
small-title,text,btn-orange
}
quadruple{
small-title,text,btn-orange
}
quadruple{
small-title,text,btn-orange
}
quadruple{
small-title,text,btn-orange
}
}
row{
double{
small-title,text,btn-orange
}
double{
small-title,text,btn-orange
}
}

忘了加  python3 ，默认用 python2 训完了报错

哭死，python2.7 没装  h5py。。。还得重训一次。。。。

gogogo，我就不信了。。。

又报这个，不过 权重文件已经生成了。

反复试验了几次，貌似它只能识别 demo 哪几张图。ㄟ( ▔, ▔ )ㄏ

试了下各种自动翻译，效果都不理想。还是自己动手丰衣足食。顺带背单词了。

手工翻了一半，用有道翻译了一半。2017.12.7 发现错误会随时更新。

12.8 更新了3个有道翻错的词。
