Ubuntu14.04 installs Keras based on Anaconda and switches the backend to Theano

0 System version Ubuntu16.04

1 System update (the speed is very slow, you can try skipping this step to see if it will affect subsequent installations)

sudo apt updatesudo apt upgrade

2 Install python basic development package

sudo apt install -y python-dev python-pip python-nose gcc g++ git gfortran vim

3 Download Anaconda and then install it in the terminal, follow the prompts to complete

chmod 777 Anaconda.shsudo ./Anaconda.sh

4 Install Anaconda You can then choose to automatically add environment variables. If the python input in the terminal is not the version of Anaconda, you can modify it accordingly: check the environment variables. If python is retrieved under /usr/bin, since this is a soft link, you can delete the original soft link and create a new one pointing to Anaconda. python under.

 -s ～/anaconda2/bin/python /usr/bin/python

5 In order to run conda in the terminal, if you have not added the environment variable, you can add the environment variable yourself: edit ~/.bashrc, add the environment variable (as shown below), and then source ~/.bashrc Or restart the terminal

export PATH=～/anaconda2/bin:$PATH

This also solves the problem in the previous step. The python version is the Anaconda version (more convenient than the solution in the previous step).

6 After changing, you can view the installed modules in the terminal

conda list

7 Download pycharm from the official website, decompress it and execute it. After running, search for the corresponding application in the dash and pull it to Taskbar as icon.

tar -xvf pycharm-community-2017.1.4.tar.gz
cd pycharm-community-2017.1.4/bin
./pycharm.sh

8 Install tensorflow and keras and test

sudo pip install tensorflowsudo pip install keras

python -c "import tensorflow"python -c "import keras"

9 Switch the backend to theonad: Find the configuration file: $HOME/ .keras/keras.json, change <span class="hljs-attribute">backend</span> field’s <span class="hljs-value"><span class="hljs-string">tensorflow</span></span> to theano
