When auto-tuning is active and the batch size is 1, fused map and batch schedules ctx->runner_threadpool_size() parallel applications of the map. For instance, on a DGX-1, 80 parallel calls of the map are invoked (vs. 2 for a batch size of 2), which can result in Out Of Memory Segfaults.

为了快速的熟悉TensorFlow编程，下面从一段简单的代码开始： import tensorflow as tf #定义‘符号’变量，也称为占位符 a = tf.placeholder("float") b = tf.placeholder("float") y = tf.mul(a, b) #构造一个op节点 sess = tf.Session() #建立会话 #运行会话，输入数据，并计算节点，同时打印结果 print sess.run(y TensorFlow的数据集 . 二、背景. 注意，在TensorFlow 1.3中，Dataset API是放在contrib包中的： tf.contrib.data. 而在TensorFlow 1.4中，Dataset API已经从contrib包中移除，变成了核心API的一员： tf. data. 此前，在TensorFlow中读取数据一般有两种方法： 使用placeholder读内存中的数据 出错：module 'tensorflow' has no attribute 'layers' 解决方法：由于已经安装的tensorflow是0.x的版本，0.x版本没有layers模块所以程序出错，需要重新安装tensorflow 1.0以上的版本，即更新tensorflow版本。 查看目前tensorflow版本 pip list 显示：如下图，此时的tensorflow为0.12 1.
