使用tensorflow model库里的cifar10 多gpu训练时,最后测试发现时间并没有减少,反而更慢 参考以下两个链接 https://github.com/keras-team/keras/issues/9204 https://medium.com/@c_61011/why-multi-gpu-training-is-not-faster-f439fe6dd6ec 原因可能是在cpu上进行参数梯度同步占每一步的很大比例 ‘’‘ It seems that CPU-side data
TensorFlow [1] is an interface for expressing machine learning algorithms, and an implementation for executing such algorithms. TensorFlow的功能:1.提供接口表达机器学习算法.2.执行这些机器学习算法. A computation expressed using TensorFlow can be executed with little or no chan
