安装tensorflow
Ubuntu 下 pycharm 安装
点击最右边加号， 选择Tensorflow 然后点击install ok 完成
使用测试代码 检查是否安装成功 定义两个常量（tf.constant) 然后将其相加 要输出相加结果 需要生成一个session来计算
import tensorflow as tf a = tf.constant([1.0,2.0], name = 'a') b = tf.constant([2.0,3.0], name="b") result = a+b sess = tf.Session() print(sess.run(result))
结果出现错误
/home/sun/PycharmProjects/mechinelearning/venv/bin/python /home/sun/PycharmProjects/mechinelearning/ch2/test.py 2019-02-09 17:59:38.627974: I tensorflow/core/platform/cpu_feature_guard.cc:141] Your cpu supports instructions that this TensorFlow binary was not compiled to use: AVX2 FMA Process finished with exit code 0
当前的cpu可以支持未编译为二进制的指令AVX2 消除此提示 添加两行代码
import os os.environ['TF_CPP_MIN_LOG_LEVEL'] = '2'
运行结果
