一、TensorFlow介绍

1、简介

TensorFlow是一个基于数据流编程（dataflow programming）的符号数学系统，被广泛应用于各类机器学习（machine learning）算法的编程实现，其前身是谷歌的神经网络算法库DistBelief 。Tensorflow拥有多层级结构，可部署于各类服务器、PC终端和网页并支持GPU和TPU高性能数值计算，被广泛应用于谷歌内部的产品开发和各领域的科学研究。TensorFlow由谷歌人工智能团队谷歌大脑（Google Brain）开发和维护，拥有包括TensorFlow Hub、TensorFlow Lite、TensorFlow Research Cloud在内的多个项目以及各类应用程序接口（Application Programming Interface, API）。自2015年11月9日起，TensorFlow依据阿帕奇授权协议（Apache 2.0 open source license）开放源代码。

2、TensorFlow 支持的系统

以下 64 位系统上测试过 TensorFlow 并且这些系统支持 TensorFlow：

Python 3.5–3.8
Ubuntu 16.04 或更高版本
Windows 7 或更高版本（含 C++ 可再发行软件包）
macOS 10.12.6 (Sierra) 或更高版本（不支持 GPU）
Raspbian 9.0 或更高版本

二、安装步骤

1、检查确认python版本

root@ubuntuvm:~# python3 -V
Python 3.8.5

2、安装venv模块

root@ubuntuvm:/home# apt install python3-venv python3-dev

python3-distutils python3.8-dev python3.8-venv zlib1g zlib1g-dev
Suggested packages:
glibc-doc
The following NEW packages will be installed:
libc-dev-bin libc6-dev libcrypt-dev libexpat1-dev libpython3-dev libpython3.8-dev linux-libc-dev manpages-dev python-pip-whl python3-dev
python3-distutils python3-venv python3.8-dev python3.8-venv zlib1g-dev
The following packages will be upgraded:
libc6 libc6-dbg zlib1g

Do you want to continue? [Y/n] y

3、创建项目目录

bdsc@ubuntuvm:~$ mkdir mytensorflow
bdsc@ubuntuvm:~$ cd mytensorflow/

4、创建虚拟环境

bdsc@ubuntuvm:~/mytensorflow$ python3 -m venv tenf

5、激活虚拟环境

bdsc@ubuntuvm:~/mytensorflow$ source tenf/bin/activate
(tenf) bdsc@ubuntuvm:~/mytensorflow$

6、升级pip

(tenf) bdsc@ubuntuvm:~/mytensorflow$ pip3 -V
pip 20.0.2 from /home/bdsc/mytensorflow/tenf/lib/python3.8/site-packages/pip (python 3.8)
(tenf) bdsc@ubuntuvm:~/mytensorflow$ pip install --upgrade pip

8、验证tensoflow是否安装成功

使用如下命令验证，输出版本号说明成功，本次安装版本为2.4.1
#python3 -c ‘import tensorflow as tf; print(tf.version)’

(tenf) bdsc@ubuntuvm:~/mytensorflow$ python3 -c ‘import tensorflow as tf; print(tf.version)’
