OpenGL and OpenCV with python 2.7 - part 002.

I deal today with opencv and I fix some of my errors.
One is this error I got with cv2.VideoCapture. When I  try to used with load video and createBackgroundSubtractorMOG2() i got this:

cv2.error:   C:\builds\master_PackSlaveAddon-win64-vc12-static\opencv\modules\highgui\src\window.cpp:281:  error: (-215) size.width<0 amp="" cv::imshow="" function="" i="" in="" size.height="">
You need also to have opencv_ffmpeg310.dll and opencv_ffmpeg310_64.dll into your Windows C:\Windows\System32, this will help me to play videos.
Now make sure you have the opencv version 3.1.0 because opencv come with some changes over python.
C:\Python27\python
Python 2.7.8 (default, Jun 30 2014, 16:08:48) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>import cv2
>>>print cv2.__version__
3.1.0

You can take some infos from about opencv python module - cv2 with:

>>>cv2.getBuildInformation()
...
>>>cv2.getCPUTickCount()
...
>>>print cv2.getNumberOfCPUs()
...
>>>print cv2.ocl.haveOpenCL()
True

You can also see some error by disable OpenCL:

>>>cv2.ocl.setUseOpenCL(False)
>>>print cv2.ocl.useOpenCL()
False

Now will show you how to use webcam gray and color , and play one video:
webcam color

import numpy as np
import cv2
cap = cv2.VideoCapture(0)
while(True):
    ret, frame = cap.read()
    cv2.imshow('frame',frame)
    if 0xFF & cv2.waitKey(5) == 27:
        break
cap.release()
cv2.destroyAllWindows()

webcam gray

import numpy as np
import cv2
cap = cv2.VideoCapture(0)
while(True):
    ret, frame = cap.read()
    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
    cv2.imshow('frame',gray)
    if 0xFF & cv2.waitKey(5) == 27:
        break
cap.release()
cv2.destroyAllWindows()

play video

import cv2
from cv2 import *
capture = cv2.VideoCapture("avi_test_001.avi")
while True:
    ret, img = capture.read()
    cv2.imshow('some', img)
    if 0xFF & cv2.waitKey(5) == 27:
        break
cv2.destroyAllWindows()

OpenGL and OpenCV with python 2.7 - part 001.

First you need to know what version of python you use.
C:\Python27>python
Python 2.7.8 (default, Jun 30 2014, 16:08:48) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>
You need also to download the OpenCV version 3.0 from here.
Then run the executable into your folder and get cv2.pyd file from \opencv\build\python\2.7\x64 and paste to \Python27\Lib\site-packages.
If you use then use 32 bit python version then use this path: \opencv\build\python\2.7\x86.
Use pip to install next python modules:
C:\Python27\Scripts>pip install PyOpenGL
...
C:\Python27\Scripts>pip install numpy
...
C:\Python27\Scripts>pip install matplotlib
...
Let's see how is working OpenGL:
C:\Python27>python
Python 2.7.8 (default, Jun 30 2014, 16:08:48) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import OpenGL
>>> import numpy
>>> import matplotlib
>>> import cv2
>>> from OpenGL import *
>>> from numpy import *
>>> from matplotlib import *
>>> from cv2 import *
You can also use dir(module) to see more. You can import all from GL, GLU and GLUT.
>>> dir(OpenGL)
['ALLOW_NUMPY_SCALARS', 'ARRAY_SIZE_CHECKING', 'CONTEXT_CHECKING', 'ERROR_CHECKING', 'ERROR_LOGGING', 'ERROR_ON_COPY', 'FORWARD_COMPATIBLE_ONLY', 'FULL_LOGGING', 'FormatHandler', 'MODULE_ANNOTATIONS', 'PlatformPlugin', 'SIZE_1_ARRAY_UNPACK', 'STORE_POINTERS', 'UNSIGNED_BYTE_IMAGES_AS_STRING', 'USE_ACCELERATE', 'WARN_ON_FORMAT_UNAVAILABLE', '__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__', '__version__', '_bi', 'environ_key', 'os', 'plugins', 'sys', 'version']
>>> from OpenGL.GL import *
>>> from OpenGL.GLU import *
>>> from OpenGL.GLUT import *
>>> from OpenGL.WGL import *
If you are very good with python OpenGL module then you can import just like this example:
>>> from OpenGL.arrays import ArrayDatatype
>>> from OpenGL.GL import (GL_ARRAY_BUFFER, GL_COLOR_BUFFER_BIT,
... GL_COMPILE_STATUS, GL_FALSE, GL_FLOAT, GL_FRAGMENT_SHADER,
... GL_LINK_STATUS, GL_RENDERER, GL_SHADING_LANGUAGE_VERSION,
... GL_STATIC_DRAW, GL_TRIANGLES, GL_TRUE, GL_VENDOR, GL_VERSION,
... GL_VERTEX_SHADER, glAttachShader, glBindBuffer, glBindVertexArray,
... glBufferData, glClear, glClearColor, glCompileShader,
... glCreateProgram, glCreateShader, glDeleteProgram,
... glDeleteShader, glDrawArrays, glEnableVertexAttribArray,
... glGenBuffers, glGenVertexArrays, glGetAttribLocation,
... glGetProgramInfoLog, glGetProgramiv, glGetShaderInfoLog,
... glGetShaderiv, glGetString, glGetUniformLocation, glLinkProgram,
... glShaderSource, glUseProgram, glVertexAttribPointer)
Most of this OpenGL need to have a valid OpenGL rendering context.
For example you can test it with WGL ( WGL or Wiggle is an API between OpenGL and the windowing system interface of Microsoft Windows):
>>> import OpenGL
>>> from OpenGL import *
>>> from OpenGL import WGL
>>> print WGL.wglGetCurrentDC()
None
Now , let's see the OpenCV python module with s=one simple webcam python script:

import numpy as np
import cv2
cap = cv2.VideoCapture(0)
while(True):
    ret, frame = cap.read()
    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
    cv2.imshow('frame',gray)
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break
cap.release()
cv2.destroyAllWindows()

This is result of my webcam:

Scrapy python module - part 001.

To install pip under python 2.7.8, securely download get-pip.py into Python27 folder.
Use this command:

Into the next tutorial I will try to use scrapy.
If you have some ideas about how to do the next step just send me one comment.

News: The new python version 3.6.0.a1

I used the Windows x86-64 executable installer to install this version of python.
I set some settings and I start the install aplication.

I read all new changes and PEP 0498.
I take a look to see all python modules:

Please wait a moment while I gather a list of all available modules...

The new formatted string literals are a new kind of string literal, prefixed with 'f' this allow you to add contain replacement fields surrounded by curly braces.
I don't think the add Python start well, maybe need restart:

 >>> import crypt
Traceback (most recent call last):
  File "", line 1, in 
  File "C:\Python36\lib\crypt.py", line 3, in 
    import _crypt
ImportError: No module named '_crypt' 

Some of changes can be see at whatsnew.
You can read more and also download the new python released version 360a1 from here.
Very good work from development team, they make a great job.

Most of my source code was wrote with python 2.7 and the next step was to using pip3.5 to update and upgrade some python modules.
I try to install PyQt4 with pip3.5 - not working.
So I used the old way: whl file from here.
That was good, most of the scripts was running.
The main problem was OpenGL and that will make errors when you try to use QtOpenGL.
The result of this seam to me the python 3.5.1 it's now without OpenGL features.

The most short source code into Python 3.5.1 .

Just type this :

import antigravity

That will open your browser with one comics from xkcd website.
The antigravity module was added to Python 3.5.1. I'm not sure but seam working also with python 2.7 version.

wmi python module - part 002.

According to MSDN Microsoft the Win32_Process WMI class represents a process on an operating system.
We can see all of the inherited properties of processes:

class Win32_Process : CIM_Process
{
  string   Caption;
  string   CommandLine;
  string   CreationClassName;
  datetime CreationDate;
  string   CSCreationClassName;
  string   CSName;
  string   Description;
  string   ExecutablePath;
  uint16   ExecutionState;
  string   Handle;
  uint32   HandleCount;
  datetime InstallDate;
  uint64   KernelModeTime;
  uint32   MaximumWorkingSetSize;
  uint32   MinimumWorkingSetSize;
  string   Name;
  string   OSCreationClassName;
  string   OSName;
  uint64   OtherOperationCount;
  uint64   OtherTransferCount;
  uint32   PageFaults;
  uint32   PageFileUsage;
  uint32   ParentProcessId;
  uint32   PeakPageFileUsage;
  uint64   PeakVirtualSize;
  uint32   PeakWorkingSetSize;
  uint32   Priority = NULL;
  uint64   PrivatePageCount;
  uint32   ProcessId;
  uint32   QuotaNonPagedPoolUsage;
  uint32   QuotaPagedPoolUsage;
  uint32   QuotaPeakNonPagedPoolUsage;
  uint32   QuotaPeakPagedPoolUsage;
  uint64   ReadOperationCount;
  uint64   ReadTransferCount;
  uint32   SessionId;
  string   Status;
  datetime TerminationDate;
  uint32   ThreadCount;
  uint64   UserModeTime;
  uint64   VirtualSize;
  string   WindowsVersion;
  uint64   WorkingSetSize;
  uint64   WriteOperationCount;
  uint64   WriteTransferCount;
};

Let's make one simple example with wmi python module.

import wmi
c = wmi.WMI()
for process in c.Win32_Process ():
 name = process.Properties_("Name").Value
 pid = process.Properties_('ProcessID').Value
 parent = process.Properties_('ParentProcessId')
 termination = process.Properties_('TerminationDate')
 print (name,' = pid -',pid,'+', parent,'|termination_date-',termination)

And the output of this script it's :

firefox.exe  = pid - 13788 + 2564 |termination_date- None
explorer.exe  = pid - 1048 + 772 |termination_date- None
sublime_text.exe  = pid - 11404 + 2564 |termination_date- None
plugin_host.exe  = pid - 7432 + 11404 |termination_date- None
cmd.exe  = pid - 9568 + 2564 |termination_date- None
conhost.exe  = pid - 14124 + 9568 |termination_date- None
conhost.exe  = pid - 9700 + 11208 |termination_date- None
Taskmgr.exe  = pid - 9424 + 13404 |termination_date- None
WmiPrvSE.exe  = pid - 9764 + 772 |termination_date- None
SpfService64.exe  = pid - 11908 + 684 |termination_date- None
python.exe  = pid - 1308 + 9568 |termination_date- None

wmi python module - part 001.

Named WMI from Windows Management Instrumentation, this python module allow you to use Microsoft’s implementation of Web-Based Enterprise Management ( WBEM ).
Is a set of extensions to the Windows Driver Model AND that provides an operating system interface.
allows you to scripting languages like VBScript to manage Microsoft Windows personal computers and servers, both locally and remotely.
You cand read about this python module here.

C:\Python34\Scripts>pip install  wmi
...

Cleaning up...

Let try first example :

C:\Python34>python
Python 3.4.1 (v3.4.1:c0e311e010fc, May 18 2014, 10:45:13) [MSC v.1600 64 bit (AM
D64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import wmi
>>> remote_process = wmi.WMI (computer="home").new ("Win32_Process")
>>> for i in wmi.WMI ().Win32_OperatingSystem ():
...     print (i.Caption)
...
Microsoft Windows 10 Home

Now let's see another example can used by you with wmi python module.
This example let you see your processes.

import wmi
import datetime
c = wmi.WMI()
process_watcher = c.Win32_Process.watch_for("modification")
while True:
  new_process = process_watcher()
  print (new_process.Caption)

I used the python version 3.3.5 and Spyder ( Scientific PYthon Development EnviRonment ) to test the script.
You can change .watch_for method args with: creation, deletion, modification or operation.

The svgwrite python module - part 001.

The svgwrite python module is a tool by Manfred Moitzi.
To install this python module use Python 3.4 version.
Then you need to install svgwrite with pip3.4:

C:\Python34\Scripts>pip3.4.exe install svgwrite
Collecting svgwrite
  Downloading svgwrite-1.1.6.tar.gz (109kB)
    100% |################################| 110kB 354kB/s

Also this svgwrite is the only module that needs to be imported and then you can deal with this module.
See this simple example:

import svgwrite
from svgwrite import *
#this will work with svgwrite
svg_doc = svgwrite.Drawing(filename = "test-svgwrite.svg",\
                                size = ("30px", "30px"))\
svg_doc.add(svg_doc.rect(insert = (0, 0),\
                                   size = ("20px", "20px"),\
                                   stroke_width = "1",\
                                   stroke = "green",\
                                   fill = "rgb(255,255,0)"))\
print(svg_doc.tostring())
svg_doc.save()

The result of this python script is this SVG file.

If you use the dir() then you can see more about this python module:

>>> dir(svgwrite)
['AUTHOR_EMAIL', 'AUTHOR_NAME', 'CYEAR', 'Drawing', 'Hz', 'Unit', 'VERSION', '__
builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__p
ackage__', '__path__', '__spec__', 'animate', 'base', 'cm', 'container', 'data',
 'deg', 'drawing', 'elementfactory', 'em', 'etree', 'ex', 'filters', 'grad', 'gr
adients', 'image', 'inch', 'kHz', 'masking', 'mixins', 'mm', 'params', 'path', '
pattern', 'pc', 'percent', 'pt', 'px', 'rad', 'rgb', 'shapes', 'text', 'utils',
'validator2', 'version']

For example you can add some text:

svg_doc.add(svg_document.text("This add new svg text",\
                                   insert = (10, 10)))

The new Python 2.7.11rc1.

The next release in the 2.7.x series is now available with the version 2.7.11.rc.1 .
This can be download it from here.
Come with source release, installer for Windows, Mac OS X 10.6 and later.
I don't use linux instalation, just on Windows 10 - 64 MSI installer.
The changes of this version can be see here.
First I saw this python version will change my old python 2.7 version.

Also I check to compile all python scripts and module.
With installed Python 2.7 I check if is all ok.

C:\Python27>python.exe
Python 2.7.11rc1 (v2.7.11rc1:82dd9545bd93, Nov 21 2015, 23:25:27) [MSC v.1500 64
 bit (AMD64)] on win32

I think the python has some problems with keep and clean correct modules under pip.
Also I guest can be done with few rows of python scripts but also this can be done by default by python installation.

WinPython - news and old stuff.

First good news: the team tells us about the WinPython will come with new release of WinPython.
This will be 3.4.3.7 version of WinPython and this will be great for most of users.
I love this portable python because first is easy to use and can easy test my python scripts.
One goal of this portable python it's the demos. I found some great demos with PyQt4 and networkx.

Also you can use Spyder to make your python scripts.
It's a free open-source development environment for the Python programming language.
This visual interface similar to MATLAB where you can run commands, edit and debug programs, check the values of variables and the definitions of functions, etc.
If you just getting started with Python then just take a look at google.com/edu/python.
The WinPython Control Panel allows to register your WinPython distribution to Windows with Advanced - Register distribution ...:
...and this allow you to:

• associate file extensions .py, .pyc and .pyo to Python interpreter
• register Python icons in Windows explorer
• add context menu entries Edit with IDLE and Edit with Spyder for .py files
• register WinPython as a standard Python distribution in the registry (the same way as the standard Python Windows installers will do)

Also you can use Jupyter Notebook web application.
This allow you to:
The Jupyter Notebook is a web application that allows you to create and share documents that contain live code, equations, visualizations and explanatory text. Uses include: data cleaning and transformation, numerical simulation, statistical modeling, machine learning and much more.
