解决了问题，如果你之前已经安装过tensorflow, python3, 先不需要按照上面的steps来操作，可以直接执行如下命令：

$ sudo easy_install pip
    $ sudo easy_install --upgrade six
    $ sudo pip install --upgrade pip
    $ pip3 install --upgrade tensorflow

看能不能解决你的问题，如果不能解决，你再按照上面链接中的steps来操作，  
最后通过如下代码验证：

$ python
    >>> import tensorflow as tf
    >>> hello = tf.constant('Hello, TensorFlow!')
    >>> sess = tf.Session()
    >>> print(sess.run(hello))

如果正常输出：“Hello, TensorFlow!” 说明安装TensorFlow成功！  
如果出现下面错误：

**2019-03-20 17:34:06.194714: I tensorflow/core/platform/cpu\_feature\_guard.cc:141\] Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX2 FMA**

说明你的CPU的不符合要求，可以暂时不用care, 依然继续执行命令，输出“Hello, TensorFlow!”依然能够成功！

我试了以下命令：

pip install --ignore-installed --upgrade "Download URL"

Download URL 替换成你的下载的URL，从下面链接中找到符合你系统要求的：
