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:
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))

P70系列延期,华为新旗舰将在下月发布
3月20日消息,近期博主@数码闲聊站 透露,原定三月份发布的华为新旗舰P70系列延期发布,预计4月份上市。
而博主@定焦数码 爆料,华为的P70系列在定位上已经超过了Mate60,成为了重要的旗舰系列之一。它肩负着重返影像领域顶尖的使命。那么这次P70会带来哪些令人惊艳的创新呢?
根据目前爆料的消息来看,华为P70系列将推出三个版本,其中P70和P70 Pro采用了三角形的摄像头模组设计,而P70 Art则采用了与上一代P60 Art相似的不规则形状设计。这样的外观是否好看见仁见智,但辨识度绝对拉满。
