Ubuntu20.04环境安装tensorflow2的方法步骤


Posted in Python onJanuary 29, 2021

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

8、验证tensoflow2是否安装成功

1、查看安装模块及版本

(tenf) bdsc@ubuntuvm:~/mytensorflow$ pip3 show tensorflow
Name: tensorflow
Version: 2.4.1
Summary: TensorFlow is an open source machine learning framework for everyone.
Home-page: https://www.tensorflow.org/
Author: Google Inc.
Author-email: packages@tensorflow.org
License: Apache 2.0
Location: /home/bdsc/mytensorflow/tenf/lib/python3.8/site-packages
Requires: typing-extensions, google-pasta, protobuf, wrapt, gast, tensorboard, opt-einsum, flatbuffers, numpy, wheel, astunparse, keras-preprocessing, six, termcolor, tensorflow-estimator, grpcio, absl-py, h5py
Required-by:

2、查看import tensorflow是否报错

Ubuntu20.04环境安装tensorflow2的方法步骤

3、使用TensorFlow打印hello,Tensorflow

(tenf) bdsc@ubuntuvm:~/mytensorflow$ python3
Python 3.8.5 (default, Jul 28 2020, 12:59:40)
[GCC 9.3.0] on linux
Type “help”, “copyright”, “credits” or “license” for more information.
>>> import os
>>> os.environ[‘TF_CPP_MIN_LOG_LEVEL'] = ‘2'
>>> import tensorflow as tf
>>> tf.compat.v1.disable_eager_execution()
>>> hello = tf.constant(‘Hello, Tensorflow!')
>>> sess = tf.compat.v1.Session()
>>> print(sess.run(hello))
b'Hello, Tensorflow!'

三、FAQ

1、import tensorflow时报错无法加载动态库libcudart.so.11.0

Ubuntu20.04环境安装tensorflow2的方法步骤

解决方法:
在import tensorflow as tf语句前加上如下语句

import os
os.environ[‘TF_CPP_MIN_LOG_LEVEL'] = ‘2'
import tensorflow as tf

Ubuntu20.04环境安装tensorflow2的方法步骤

2、报错session属性找不到

Ubuntu20.04环境安装tensorflow2的方法步骤

原因:
报错AttributeError: module ‘tensorflow' has no attribute ‘Session'。这其实不是安装错误,是因为在新的Tensorflow 2.0版本中已经移除了Session这一模块。
解决方法:
改换运行代码,tf.compat.v1.Session()
