一、Anaconda，下载

Anaconda 安装包可以到 https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/ 下载。

ps:也可以去官网下载 https://www.anaconda.com/download/

ps:本次使用的是Anaconda3-5.0.0-Linux-x86_64.sh

二、Anaconda，安装

进入文件目录：

[code]bash ./Anaconda3-5.0.0-Linux-x86_64.sh

• 1

回车

.
.
.

三、Anaconda，环境变量

1.检查环境变量，没有则添加

查看命令

[code]sudo gedit ~/.bashrc

检查末尾是否已经添加如下变量，没有则添加

[code]export PATH="/home/用户名/anaconda3/bin:$PATH"

• 1

需要重启系统，不然找不到命令

2.打开控制台 ，更换清华源（墙太高）

[code]conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --set show_channel_urls yes

3.创建一个名flappbird 的环境

[code]conda create -n flappbird python=3.6

创建成功

激活环境

[code]source activate flappbird

四、tensorflow安装

给 flappbird 环境安装tensorflow

[code]conda install -n flappbird -c https://conda.anaconda.org/jjhelmus tensorflow

五、遇到的错误+解决办法

1.如果换源之后任然无法创建环境，并且报网络连接的错误：

报错如下：

[code]CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://repo.continuum.io/pkgs/main/linux-64/repodata.json.bz2>
Elapsed: -

An HTTP error occurred when trying to retrieve this URL.
HTTP errors are often intermittent, and a simple retry will get you on your way.
ConnectionError(MaxRetryError("HTTPSConnectionPool(host='repo.continuum.io', port=443): Max retries exceeded with url: /pkgs/main/linux-64/repodata.json.bz2 (Caused by NewConnectionError('<urllib3.connection.VerifiedHTTPSConnection object at 0x7fd5d462df28>: Failed to establish a new connection: [Errno 101] Network is unreachable',))",),)

解决办法：
打开源文件

[code]vim  ~/.condarc

删除defaults行

2.如果安装文件夹出现一把小锁，运行命令报错

报错如下

[code]Traceback (most recent call last):

解决办法：
运行如下命令，赋予权限

[code]sudo chmod -R 777 Anaconda

ps:其中Anaconda是我的安装的文件夹名字
