ubuntu16.04 python3安装opencv及tensorflow

重装系统以后，安装深度学习环境还真麻烦，我这里对装tensorflow python3的环境进行整理：

sudo apt-get install python3-pip

sudo pip3 install tensorflow-gpu

sudo pip3 install opencv-python

我们还可能用到jupyter notebook,安装命令如下：

sudo pip3 install jupyter

python下查看opencv版本：

python
import cv2
cv2.__version__

命令行输入：

python3

然后运行tensorflow安装成功测试代码：

import tensorflow as tf
hello = tf.constant('Hello, TensorFlow!')
sess = tf.Session()
print( sess.run(hello))
a = tf.constant(10)
b = tf.constant(32)
print(sess.run(a+b))

会有打印输出，例如，我在TX2上安装成功后，输出为：

ubuntu@tegra-ubuntu:~$ python3

会有你的显卡输出信息，我这里是tx2
