今天遇到一个奇怪的现象,使用tensorflow-gpu的时候,出现内存超额~~如果我训练什么大型数据也就算了,关键我就写了一个y=W*x…显示如下图所示:

程序如下:

import tensorflow as tf

w = tf.Variable([[1.0,2.0]])
b = tf.Variable([[2.],[3.]])

y = tf.multiply(w,b)

init_op = tf.global_variables_initializer()

with tf.Session() as sess:
 sess.run(init_op)
 print(sess.run(y))

出错提示:

占用的内存越来越多,程序崩溃之后,整个电脑都奔溃了,因为整个显卡全被吃了

分析原因:

显卡驱动不是最新版本,用__驱动软件__更新一下驱动,或者自己去下载更新。

TF运行太多,注销全部程序冲洗打开。

由于TF内核编写的原因,默认占用全部的GPU去训练自己的东西,也就是像meiguo一样优先政策吧

这个时候我们得设置两个方面:

  • 选择什么样的占用方式?优先占用__还是__按需占用
  • 选择最大占用多少GPU,因为占用过大GPU会导致其它程序奔溃。最好在0.7以下

先更新驱动:

解决TensorFlow程序无限制占用GPU的方法

再设置TF程序:

注意:单独设置一个不行!按照网上大神博客试了,结果效果还是很差(占用很多GPU)

设置TF:

  • 按需占用
  • 最大占用70%GPU

修改代码如下:

import tensorflow as tf

w = tf.Variable([[1.0,2.0]])
b = tf.Variable([[2.],[3.]])

y = tf.multiply(w,b)

init_op = tf.global_variables_initializer()

config = tf.ConfigProto(allow_soft_placement=True)
gpu_options = tf.GPUOptions(per_process_gpu_memory_fraction=0.7)
config.gpu_options.allow_growth = True
with tf.Session(config=config) as sess:
 sess.run(init_op)
 print(sess.run(y))

成功解决:

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!

昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。

这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。

而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
