1.指定GPU运算 如果安装的是GPU版本,在运行的过程中TensorFlow能够自动检测.如果检测到GPU,TensorFlow会尽可能的利用找到的第一个GPU来执行操作. 如果机器上有超过一个可用的GPU,除了第一个之外的其他的GPU默认是不参与计算的.为了让TensorFlow使用这些GPU,必须将OP明确指派给他们执行.with......device语句能够用来指派特定的CPU或者GPU执行操作: import tensorflow as tf import numpy as np w
TensorFlow指定GPU/CPU进行训练和输出devices信息 1.在tensorflow代码中指定GPU/CPU进行训练 with tf.device('/gpu:0'): .... with tf.device('/gpu:1'): ... with tf.device('/cpu:0'): ... 2.输出devices的信息 在指定devices的时候往往不知道具体的设备信息,这时可用下面的代码查看对应的信息 进入Python环境 from tensorflow.python.c
TensorFlow指定CPU和GPU方法 TensorFlow 支持 CPU 和 GPU.它也支持分布式计算.可以在一个或多个计算机系统的多个设备上使用 TensorFlow. TensorFlow 将支持的 CPU 设备命名为"/device:CPU:0"(或"/cpu:0"),第 i 个 GPU 设备命名为"/device:GPU:I"(或"/gpu:I"). 如前所述,GPU 比 CPU 要快得多,因为它们有许多小的内
