我安装了 Tensorflow，到目前为止运行良好。但是，当我执行代码时，它显示以下内容
2017-05-07 12:35:10.449884: W tensorflow/core/platform/cpu_feature_guard.cc:45] The TensorFlow library wasn't compiled to use SSE4.1 instructions, but these are available on your machine and could speed up CPU computations.

我尝试了很多不同的解决方案，但都没有用。有一个使用 Bazel 的解决方案，但我想我没用过这个应用。我该如何解决这个问题？

但是，如果我关闭终端并再次打开它，我会得到同样的错误。如何让这个伟大的解决方案export TF_CPP_MIN_LOG_LEVEL=3永久有效？
提前致谢！

类似的问题已发布在堆栈溢出。您可以忽略这些警告。如果它们让您烦恼，您可以使用 来掩盖它们os.environ['TF_CPP_MIN_LOG_LEVEL'] = '3'，例如：
import tensorflow as tf
import os
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '3'
print('TensorFlow version: {0}'.format(tf.__version__))
hello = tf.constant('Hello, TensorFlow!')
sess = tf.Session()
print(sess.run(hello))
