Pillow environment construction --Virtual environment by virtualenv, interactive environment by iPython
What you want to do
--Pillow's (probably) powerful graphics processing
--Using virtualization with virtualenv, which is easy to maintain
--Easy to use iPython
Realize a Python processing environment.
Prerequisites
It is assumed that Python 3.4, pip, and virtualenv are already installed.
Building a virtual environment
Create a working directory called py3 and build a virtual environment called box01 in it.
python
mkdir py3
virtualenv --python=python3.4 py3/box01
cd py3/box01
Enable virtual environment
python
source bin/activate
Install Pillow in virtual environment
python
pip install pillow
Install iPython and other modules in the virtual environment
python
pip install ipython3
pip install jinja2
pip install tornado
pip install pyzmq
pip install numpy
pip install matplotlib
pip install pandas
pip install scipy
pip install jsonschema #I was angry if I didn't enter later
pip install requests #Required to run iptest3
pip install mistune #Below, in iptest3, I was told that it was not included
pip install pygments
pip install pymongo
pip install sphinx
Test if iPython can run
If you install iPython3, a command called iptest3 will come with it and it will check if it can be executed.
python
iptest3
Execution result (excerpt)
python
Test suite completed for system with the following information:
IPython version: 3.0.0
IPython commit : f75fda4 (installation)
IPython package: ~/py3/box01/lib/python3.4/site-packages/IPython
Python version : 3.4.2 (default, Oct 8 2014, 13:18:07) [GCC 4.9.1]
sys.executable : ~/py3/box01/bin/python3.4
Platform : Linux-3.16.0-31-generic-i686-with-Ubuntu-14.10-utopic
Tools and libraries available at test time:
curses jinja2 jsonschema matplotlib mistune numpy pexpect pygments pymongo requests sphinx sqlite3 terminado tornado zmq
Tools and libraries NOT available at test time:
casperjs phantomjs qt slimerjs
I didn't know what to do with the bottom four.
After all, the module configuration I put in was as follows. (As a result of trial and error, it seems that unnecessary modules are also included.)

iPython server settings
Create profile
python
ipython3 profile create py3nb
Create password string
Launch ipyton3 from the console
python
ipyton3
python
from IPython.lib import passwd
passwd()
(Enter the password you want to set twice)
'sha1:
Once exit from ipyton3
python
exit()
Edit Notebook configuration file
Create a new setting file python_notebook_config.py
python
vi ~/.ipython/profile_py3nb/ipython_notebook_config.py
py3:~/.ipython/profile_py3nb/ipython_notebook_config.py
c = get_config()
c.NotebookApp.ip = '*'
c.NotebookApp.open_browser = False
c.NotebookApp.port = 9999
c.NotebookApp.password = 'sha1:<String>' # 先ほど作成したパスワードString
There is a possibility that this area is wrong because I worked with a lot of momentum.
Setting the execution script at startup
python
vi ~/.ipython/profile_py3nb/startup/00-startup.py
py3:~/.ipython/profile_py3nb/startup/00-startup.py
#! /usr/bin/env python
# -*- coding: utf-8 -*-
import sys, os
import readline
import numpy as np
import scipy as sp
import pandas as pd
import matplotlib.pyplot as plt
# EOF
Launching a notebook
python
ipython3 notebook --profile=py3nb
It seems that the --pylab = inline option has been abolished.
Access from browser http://<ノートブックサーバーのIPアドレス>:9999/
Enter your password and put it in your notebook.
Operation check
Below, run on iPython notebook
It seems that I have to do this first.
python
%pylab inline
1 First, check the matplotlib plot
(Previously confirmed operation)
python
x = np.arange(-3, 3, .1)
y = np.sin(x)
plt.plot(x, y)
2 Pillow operation check
Pillow import
python
from PIL import Image
Load image (upload image file to server in advance)
python
img = np.array( Image.open('<Image file name>') )
Image display. It doesn't seem to be displayed in img.show ().
python
plt.imshow(img)
Run screenshot
Let's use
Since the current directory seems to be messy, create a working directory called ipy under ~ / py3 / box01, and under that in-image / (for input) out-image / (for output) work-image / (for work) I create a directory called, and put the image files in this directory.
↓ I created a shell script for starting like this.
run_ipy.sh
#! /bin/bash
source ~/py3/box01/bin/activate
cd ~/py3/box01/ipy
~/py3/box01/bin/ipython3 notebook --profile=py3nb
# EOF
