更新時(shí)間：2021年01月29日 14:55:58 作者：浪子吳天
這篇文章主要介紹了Ubuntu20.04環(huán)境安裝tensorflow2的實(shí)現(xiàn)，文中通過(guò)示例代碼介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值，需要的朋友們下面隨著小編來(lái)一起學(xué)習(xí)學(xué)習(xí)吧
一、TensorFlow介紹
1、簡(jiǎn)介
TensorFlow是一個(gè)基于數(shù)據(jù)流編程（dataflow programming）的符號(hào)數(shù)學(xué)系統(tǒng)，被廣泛應(yīng)用于各類(lèi)機(jī)器學(xué)習(xí)（machine learning）算法的編程實(shí)現(xiàn)，其前身是谷歌的神經(jīng)網(wǎng)絡(luò)算法庫(kù)DistBelief 。Tensorflow擁有多層級(jí)結(jié)構(gòu)，可部署于各類(lèi)服務(wù)器、PC終端和網(wǎng)頁(yè)并支持GPU和TPU高性能數(shù)值計(jì)算，被廣泛應(yīng)用于谷歌內(nèi)部的產(chǎn)品開(kāi)發(fā)和各領(lǐng)域的科學(xué)研究 。TensorFlow由谷歌人工智能團(tuán)隊(duì)谷歌大腦（Google Brain）開(kāi)發(fā)和維護(hù)，擁有包括TensorFlow Hub、TensorFlow Lite、TensorFlow Research Cloud在內(nèi)的多個(gè)項(xiàng)目以及各類(lèi)應(yīng)用程序接口（Application Programming Interface, API）。自2015年11月9日起，TensorFlow依據(jù)阿帕奇授權(quán)協(xié)議（Apache 2.0 open source license）開(kāi)放源代碼 。
2、TensorFlow 支持的系統(tǒng)
以下 64 位系統(tǒng)上測(cè)試過(guò) TensorFlow 并且這些系統(tǒng)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++ 可再發(fā)行軟件包）
- macOS 10.12.6 (Sierra) 或更高版本（不支持 GPU）
- Raspbian 9.0 或更高版本
二、安裝步驟
1、檢查確認(rèn)python版本
root@ubuntuvm:~# python3 -V Python 3.8.5
2、安裝venv模塊
root@ubuntuvm:/home# apt install python3-venv python3-dev Reading package lists… Done Building dependency tree Reading state information… Done The following additional packages will be installed: libc-dev-bin libc6 libc6-dbg libc6-dev libcrypt-dev libexpat1-dev libpython3-dev libpython3.8-dev linux-libc-dev manpages-dev python-pip-whl 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 3 upgraded, 15 newly installed, 0 to remove and 233 not upgraded. Need to get 21.2 MB of archives. After this operation, 56.1 MB of additional disk space will be used. Do you want to continue? [Y/n] y
3、創(chuàng)建項(xiàng)目目錄
bdsc@ubuntuvm:~$ mkdir mytensorflow bdsc@ubuntuvm:~$ cd mytensorflow/
4、創(chuàng)建虛擬環(huán)境
bdsc@ubuntuvm:~/mytensorflow$ python3 -m venv tenf
5、激活虛擬環(huán)境
bdsc@ubuntuvm:~/mytensorflow$ source tenf/bin/activate (tenf) bdsc@ubuntuvm:~/mytensorflow$
6、升級(jí)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 Collecting pip Downloading pip-21.0-py3-none-any.whl (1.5 MB) |████████████████████████████████| 1.5 MB 1.0 MB/s Installing collected packages: pip Attempting uninstall: pip Found existing installation: pip 20.0.2 Uninstalling pip-20.0.2: Successfully uninstalled pip-20.0.2 Successfully installed pip-21.0 (tenf) bdsc@ubuntuvm:~/mytensorflow$ pip3 -V pip 21.0 from /home/bdsc/mytensorflow/tenf/lib/python3.8/site-packages/pip (python 3.8)
7、安裝tensorflow

8、驗(yàn)證tensoflow2是否安裝成功
1、查看安裝模塊及版本
(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是否報(bào)錯(cuò)
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 “l(fā)icense” 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時(shí)報(bào)錯(cuò)無(wú)法加載動(dòng)態(tài)庫(kù)libcudart.so.11.0
解決方法：
在import tensorflow as tf語(yǔ)句前加上如下語(yǔ)句
import os os.environ[‘TF_CPP_MIN_LOG_LEVEL'] = ‘2' import tensorflow as tf
2、報(bào)錯(cuò)session屬性找不到
原因：
報(bào)錯(cuò)AttributeError: module ‘tensorflow' has no attribute ‘Session'。這其實(shí)不是安裝錯(cuò)誤，是因?yàn)樵谛碌腡ensorflow 2.0版本中已經(jīng)移除了Session這一模塊。
解決方法：
改換運(yùn)行代碼，tf.compat.v1.Session()
