ubuntu安裝python3.5+pycharm+anaconda+keras(theano+tensorflow)(非GPU)

一,切換python版本為3.5

裝好ubuntu,python版本是2.7的

我自己安裝並更改開啟為python3.5

sudo apt-get install python3.5

設定優先順序和預設環境:

sudo update-alternatives --install /usr/bin/python python /usr/bin/python2 100

sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 150

切換版本:

update-alternatives --config python

可看見python已經為3.5了。

二,安裝pycharm:

下載了這個,然後解壓

啟動pycharm,

下面啟用:


新增下面一行到hosts檔案,目的是遮蔽掉Pycharm對啟用碼的驗證
0.0.0.0 account.jetbrains.com

開啟PyCharm,選擇Activate code(用啟用碼啟用)

複製下載啟用碼,填入啟用碼框。

三,安裝anaconda

下載python3.5對應的版本

然後:

~$ cd 下載
~/下載$ bash Anaconda2-4.2.0-Linux-x86_64.sh

這裡需要一直按Enter,直到出現需要輸入yes or no 。輸入yes後,會顯示Anaconda將要安裝到哪個目錄下,可以自行修改,這裡我選擇預設的路徑,直接回車。最後會提示新增環境變數,輸入yes後,安裝完成。

四,安裝Theano(keras的一個後端)

安裝完Anaconda後,我們就可以使用conda這個命令了。(之前有遇到過安裝完成Anaconda後,不能使用conda的問題,這個時候需要重新啟動你的終端,問題就解決了)

在終端輸入‘conda list’來檢視安裝好的

將需要的依賴包列出來,進入anaconda3/bin 這個目錄下,使用‘sudo apt-get install xxx’命令來安裝,如下所示。

python-numpy

 然後安裝theano

conda install theano

安裝完成後,我們可以進入Python,測試一下是否安裝成功。

可以看到theano確實安裝成功了。這個測試要跑好久,著急的可以直接ctrl+c 跳出

四,安裝Tensorflow(keras的另一個後端)

pip install tensorflow

測試tensorflow安裝成功

五:安裝keras

接下來終於可以安裝keras了,直接從github上將原始碼克隆下來,這樣可以安裝最新版的keras。我將keras克隆到Anaconda安裝目錄的同級目錄下。

git clone https://github.com/fchollet/keras.git

進入keras目錄,執行命令:

~$ cd keras
~/keras$python setup.py install

keras框架基本搭建完成,可以看到keras預設後端確實是tensorflow,如果不裝的話會報錯。

下面演示切換keras後端

~$ cd .keras
~/.keras$ vim keras.json

pycharm中更改直譯器路徑。

ok,,結束。

安裝opencv

pip install opencv-contrib-python
