Tensorflow笔记

性能：

https://www.tensorflow.org/performance/performance_guide

• Build and install from source
• Utilize queues for reading data
• Preprocessing on the CPU ：放在GPU，会CPU->GPU(Preprocessing)->CPU->GPU；放在CPU，加速6倍；
• Use NCHW image data format
• Place shared parameters on the GPU
• Use fused batch norm : fused选项，让多个小操作放到同一个kernel里
