一、Anaconda，下載

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

二、Anaconda，安裝

進入檔案目錄：

bash ./Anaconda3-5.0.0-Linux-x86_64.sh

• 1

回車

三、Anaconda，環境變數

1.檢查環境變數，沒有則新增

檢視命令

sudo gedit ~/.bashrc

檢查末尾是否已經新增如下變數，沒有則新增

export PATH="/home/使用者名稱/anaconda3/bin:$PATH"

• 1

需要重啟系統，不然找不到命令

2.開啟控制檯 ，更換清華源（牆太高）

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.建立一個名flappbird 的環境

conda create -n flappbird python=3.6

建立成功

啟用環境

source activate flappbird
 

四、tensorflow安裝

給 flappbird 環境安裝tensorflow

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

五、遇到的錯誤+解決辦法

1.如果換源之後任然無法建立環境，並且報網路連線的錯誤：

報錯如下：

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',))",),)
 

解決辦法：
開啟原始檔

vim  ~/.condarc

刪除defaults行

2.如果安裝資料夾出現一把小鎖，執行命令報錯

報錯如下

    PermissionError: [Errno 13] Permission denied: '/home/joahluo/Anaconda/pkgs/cache/09e2740c.json'

解決辦法：
執行如下命令，賦予許可權

sudo chmod -R 777 Anaconda

ps:其中Anaconda是我的安裝的資料夾名字
