python3下安装tensorflow，感觉安装成功了可是总是有奇怪的东西跑出来？

Question

已安装python3.6，现在安装tensorflow，下好安装包，放在python的scripts文件夹中。
在cmd中输入pip install tensorflow回车（尝试了好几次）。出现下面的数据：
Microsoft Windows 版本 10.0.17134.285 2018 Microsoft Corporation。保留所有权利。

You are using pip version 9.0.1, however version 18.0 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

我看出现Requirement already satisfied: tensorflow in c:\users\lenovo\appdata\local\programs\python\python36\lib\site-packages
不是就是安装成功了吗？

可是我在调用的时候又出现了这个：
=================== RESTART: D:\python-files\keras\num.py ===================

反正就是又失败了。

所以我这个tensorflow是安装成功了还是失败了？为什么会这样嘞？

我也有这种情况，在Ubuntu16.04中，用pip3安装tensorflow-GPU似乎是安装成功了，因为在Python中import tensorflow as tf之后，查询tensorflow版本是1.6.0是对的。
但是，当我运行程序时，却显示ImportError: No module named 'tensorflow'。
又尝试pip安装，就显示的和博主一样了，各种Requirement already satisfied。
没办法我只能用anaconda安装，tensorflow是可以用了。但是还是想搞明白为啥之前用pip安装，Python中显示已经安装了tensorflow，但是却不能使用的原因，如何解决这个问题。
