我有这些警告:TensorFlow似乎没有安装

2017年9月26日14:50:45.956966:W tensorflow /核心/平台/ cpu_feature_guard.cc:45] TensorFlow库WASN”编译为使用SSE4.2指令,但这些指令可在您的机器上使用,并可加速CPU计算。 TensorFlow库未编译为使用AVX指令,但这些指令可在您的机器上使用,并且可以加速CPU计算。 TensorFlow库没有被编译为使用AVX2指令,但是这些指令在您的机器上可用,并且可以加速CPU计算。

因此,基于我的互联网上找到,然后我跟着这个链接:

https://www.tensorflow.org/install/install_sources

然而,当我尝试:

$ python 

和:

# Python 
import tensorflow as tf 
hello = tf.constant('Hello, TensorFlow!') 
sess = tf.Session() 
print(sess.run(hello)) 

输出应该是:Hello, TensorFlow!

不过,我不明白,在所有...

我即使在安装了它,我仍然有警告,为何如此?我使用Xcode 7.3,并没有将GPU放入./configuration进程。

有什么想法? :/ 预先感谢 !

可以掩盖这些警告像这样:

import os 
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '3' 

注意,你的程序仍输出,只是简单地后所有关于SSE4.2警告的“你好,TensorFlow!”。

通过这样做,你只会隐藏不回答我的问题的日志,不是吗?感谢您的帮助 ! – Emixam23
