Fix PyCharm error install python module from conda .

Today I fix an error about PyCharm and conda.
As you know :
Conda is an open source package management system and environmental management system that runs on Windows, macOS and Linux.
Also, Conda quickly installs, runs and updates packages dependency and environment management for any language—Python, R, Ruby, Lua, Scala, Java, JavaScript, C/ C++, FORTRAN.
This error is from PyCharm install python modules using error check from PyCharm (Alt+Enter keys):

The result of this install come with this error from conda :

Close your PyCharm and use this command into your shell-like administrator:

C:\WINDOWS\system32>conda config --show

This command installs anaconda and updates it using my account catafest .
Start the I.D.E. PyCharm and after indexing all you can try to fix the python install module (Alt+Enter keys).
If the python modules are not into conda repo from PyCharm then you can use this command:

C:\WINDOWS\system32>conda install -c conda-forge opencv

In this example I used OpenCV python module named into python script like cv2, see the next image:

Using kivy python module with PyCharm IDE.

First, you need to download the last version of PyCharm IDE.
My PyCharm IDE put the python version 3 into a folder named Miniconda3.
I use the command shell to go to Scripts and I used pip to install the kivy python module, see:

I got one error about SDL and I put the SDL 2.0 into my windows system 32 folders.
The next step is to try to use this steps from the official website into the Scripts folder from Miniconda3.

python -m pip install --upgrade pip wheel setuptools
python -m pip install docutils pygments pypiwin32 kivy.deps.sdl2 kivy.deps.glew
python -m pip install kivy.deps.gstreamer
python -m pip install kivy.deps.angle
python -m pip install kivy

I make one project into my PyCharm editor and I use the default script:

from kivy.app import App
from kivy.uix.button import Button

class TestApp(App):
    def build(self):
        return Button(text='Hello World')

TestApp().run()

The result can be see into the next image:

The Google Cloud Pub/Sub python module.

This is a test of google feature from cloud.google.com/pubsub web page.
The Google development team tell us about this service:
The Google Cloud Pub/Sub service allows applications to exchange messages reliably, quickly, and asynchronously. To accomplish this, a producer of data publishes a message to a Cloud Pub/Subtopic. A subscriber client then creates a subscription to that topic and consumes messages from the subscription. Cloud Pub/Sub persists messages that could not be delivered reliably for up to seven days. This page shows you how to get started publishing messages with Cloud Pub/Sub using client libraries.
The simple idea about this is:
Publisher applications can send messages to a topic, and other applications can subscribe to that topic to receive the messages.
I start with the installation of the python module using python version 2.7 and pip tool.

C:\Python27>cd Scripts

The next steps come with some settings on google console, see this google page.
The default settings can be started and set with this command: gcloud init .
You need to edit this settings and app.yaml at ~/src/.../appengine/flexible/pubsub$ nano app.yaml.
After that, you set all of this using the command gcloud app deploy you can see the output at https://[YOUR_PROJECT_ID].appspot.com.
The main goal of this tutorial was to start and run the Google Cloud Pub/Sub service with python and this has been achieved.

The online editor for python and google .

This is a good online editor for python and google.
Like any online editor, some python modules are not available for online security reasons.
I do not know what python modules are implemented in this online editor.
I tested just sys and math python modules.
The Google Apps come with this tool integration like application for Google drive:
Edit your python file directly in your browser:
- Save it to Google Drive integrated with Google Drive
- Test it in your browser with Skulpt
- Use autocompletion code (CTRL+SPACE)
- No registration required and totally free
- Export your file
- Work offline
New python libraries partially supported: numpy, matplotlib.

The capstone python module - disassembly framework.

The official python module comes with this info about this python module:
Capstone is a disassembly framework with the target of becoming the ultimate
the disasm engine for binary analysis and reversing in the security community.

Created by Nguyen Anh Quynh, then developed and maintained by a small community,
Capstone offers some unparalleled features:

- Support multiple hardware architectures: ARM, ARM64 (ARMv8), Mips, PPC & X86.

- Having clean/simple/lightweight/intuitive architecture-neutral API.

- Provide details on disassembled instruction (called “decomposer” by others).

- Provide semantics of the disassembled instruction, such as list of implicit
registers read & written.

- Implemented in pure C language, with lightweight wrappers for C++, Python,
Ruby, OCaml, C#, Java and Go available.

- Native support for Windows & *nix platforms (with OSX, Linux, *BSD & Solaris
have been confirmed).

- Thread-safe by design.

- Distributed under the open source BSD license.
Today I tested this python module with python version 2.7.
First I need to use a build of this python module from the official website.
I used binaries 32 bits like my python 2.7 and I tested with pip 2.7:

C:\Python27\Scripts>pip install capstone
Requirement already satisfied: capstone in c:\python27\lib\site-packages

Let's make a simple test with this python module:

C:\Python27>python.exe

...     CS_ARCH_X86,
...     CS_MODE_32,
...     CS_OPT_SYNTAX_ATT,
... )
>>> mode=Cs(CS_ARCH_X86, CS_MODE_32)
>>> mode.syntax = CS_OPT_SYNTAX_ATT
>>> def D_ASM(code):
...     for address, size, mnemonic, op_str in mode.disasm_lite(code, offset=0x08048060):
...         print("0x{0:x}\t{1:d}\t{2:s}\t{3:s}".format(address, size,mnemonic, op_str))
...
>>> D_ASM(b"\xe1\x0b\x40\xb9\x20\x04\x81\xda\x20\x08\x02\x8b")
0x8048060       2       loope   0x804806d

It seems to work very well.

The python-vlc python module.

The python module for vlc is named python-vlc.
This python module let you test libvlc API like the VLC video player.
You can install it easily with pip python tool.

C:\Python27\Scripts>pip2.7.exe install python-vlc

Let's see a simple example with this python module:

import os
import sys
import vlc
import pygame
 
def call_vlc(self, player):
 
    player.get_fps()
    player.get_time()
 
if len( sys.argv )< 2 or len( sys.argv )> 3:
        print 'Help: python vlc_001.py your_video.mp4'
else:
    pygame.init()
    screen = pygame.display.set_mode((800,600),pygame.RESIZABLE)
    pygame.display.get_wm_info()
    pygame.display.get_driver()

 
    # get path to movie specified as command line argument
    movie = os.path.expanduser(sys.argv[1])
    # see if movie is accessible
    if not os.access(movie, os.R_OK):
        print('Error: %s wrong read file: ' % movie)
        sys.exit(1)
 
    # make instane of VLC and create reference to movie.
    vlcInstance = vlc.Instance()
    media = vlcInstance.media_new(movie)
 
    # make new instance of vlc player
    player = vlcInstance.media_player_new()
 
    # start with a callback
    em = player.event_manager()
    em.event_attach(vlc.EventType.MediaPlayerTimeChanged, \
        call_vlc, player)
 
    # set pygame window id to vlc player
    win_id = pygame.display.get_wm_info()['window']
    if sys.platform == "win32": # for Windows
        player.set_hwnd(win_id)
 
    # load movie into vlc player instance
    player.set_media(media)
 
    # quit pygame mixer to allow vlc full access to audio device
    pygame.mixer.quit()
 
    # start movie play
    player.play()
 
    while player.get_state() != vlc.State.Ended:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                sys.exit(2)

The base of this python script is to make an instance of vlc and put into the pygame display.

The numba python module - part 002 .

Today I tested how fast is jit from numba python and fibonacci math function.
You will see strange output I got for some values.
First example:

import numba
from numba import jit
from timeit import default_timer as timer

def fibonacci(n):
    a, b = 1, 1
    for i in range(n):
        a, b = a+b, a
    return a
fibonacci_jit = jit(fibonacci)

start = timer()
fibonacci(100)
duration = timer() - start

startnext = timer()
fibonacci_jit(100)
durationnext = timer() - startnext

print(duration, durationnext)

The result of this run is:

C:\Python27>python numba_test_003.py

(1.5074824049540363e-05, 0.1847134227837042)

As you can see the fibonacci function is not very fast.
The jit - just-in-time compile is very fast.
Let's see if the python source code may slow down.
Let's see the new source code with jit will not work well:

import numba
from numba import jit
from timeit import default_timer as timer

def fibonacci(n):
    a, b = 1, 1
    for i in range(n):
        a, b = a+b, a
    return a
fibonacci_jit = jit(fibonacci)

start = timer()
print fibonacci(100)
duration = timer() - start

startnext = timer()
print fibonacci_jit(100)
durationnext = timer() - startnext

print(duration, durationnext)

The result is this:

C:\Python27>python numba_test_003.py

1445263496
(0.0007348174871807866, 0.17523103771560608)

The result for value 100 is not the same: 927372692193078999176 and 1445263496.
The first problem is:
The problem is that numba can't intuit the type of lookup. If you put a print nb.typeof(lookup) in your method, you'll see that numba is treating it as an object, which is slow.
The second problem is the output but can be from the same reason.
I test with value 5 and the result is :

The numba python module - part 001 .

Today I tested the numba python module.
This python module allows us to speed up applications with high-performance functions written directly in Python.
The numba python module works by generating optimized machine code using the LLVM compiler infrastructure at import time, runtime, or statically.
The code can be just-in-time compiled to native machine instructions, similar in performance to C, C++ and Fortran.
For the installation I used the pip tool:

C:\Python27>cd Scripts

C:\Python27\Scripts>pip install numba
Collecting numba

C:\Python27\Scripts>pip install numpy
Requirement already satisfied: numpy in c:\python27\lib\site-packages

The example test from official website working well:
The example source code is:

from numba import jit
from numpy import arange

# jit decorator tells Numba to compile this function.
# The argument types will be inferred by Numba when function is called.
@jit
def sum2d(arr):
    M, N = arr.shape
    result = 0.0
    for i in range(M):
        for j in range(N):
            result += arr[i,j]
    return result

a = arange(9).reshape(3,3)
print(sum2d(a))

The result of this run python script is:

C:\Python27>python.exe numba_test_001.py
36.0

Another example using just-in-time compile is used with Numba’s jit function:

import numba
from numba import jit

def fibonacci(n):
    a, b = 1, 1
    for i in range(n):
        a, b = a+b, a
    return a

print fibonacci(10)

fibonacci_jit = jit(fibonacci)
print fibonacci_jit(14)

Also, you can use jit is as a decorator:

@jit
def fibonacci_jit(n):
    a, b = 1, 1
    for i in range(n):
        a, b = a+b, a

    return a

Numba is a complex python module because use compiling.
First, compiling takes time, but will work especially for small functions.
The Numba python module tries to do its best by caching compilation as much as possible though.
Another note: not all code is compiled equally.

YARA another python module - part 002 .

This is another part of YARA python tutorial and the goal of this part is to install the Yara modules.
This is another python module about Yara named yara-python from VirusTotal.
The last tutorial uses the Yara python module.
The YARA modules provide extending features to allow us to define data structures and functions which can be used in your rules to express more complex conditions.
You can also write your own modules.
Some known modules used by YARA are:

• PE
• ELF
• Cuckoo
• Magic
• Hash
• Math

First, you need to install or reinstall YARA to the last version:

>>> yara.__version__
'3.6.3'

The Cuckoo module enables you to create YARA rules based on behavioral information generated by a Cuckoo sandbox.

Let's test this python module:

>>> import cuckoo
>>> from cuckoo import *
>>> dir(cuckoo)
['__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__', '__version__',

 'auxiliary', 'common', 'compat', 'core', 'machinery', 'misc', 'plugins', 'processing', 

'reporting', 'signatures', 'web']

Let's test some yara modules:

>>> import yara
>>> rule = yara.compile(source='import \"pe\"')
>>> rule = yara.compile(source='import \"elf\"')
>>> rule = yara.compile(source='import \"cuckoo\"')
>>> rule = yara.compile(source='import \"math\"')

I could not use the YARA modules: hash and magic.
I will solve this problem in the future.
You can also write your own modules ( see this webpage ).

The beauty of Python: subprocess module - part 004 .

This series of python tutorials that we started at the beginning of this blog and called "The beauty of Python" is part of the series of tutorials aimed at the simplicity and beauty of the Python programming language.
The main goal for us is how to use this programming language in everyday life with different tasks.
Today I will come up with examples to cover this goal and show you how to use the subprocess python module.

• using the PowerShell with python :

>>> import subprocess
>>> process=subprocess.Popen(["powershell","Get-Childitem C:\\Windows\\*.log"],stdout=subprocess.PIPE);
>>> result=process.communicate()[0]
>>> print result

• get and print the hostname :

>>> print subprocess.check_output("hostname")

• print the output of ping command :

>>> print subprocess.check_output("ping localhost", shell=True)

• print the output of dir command :

>>> cmd = 'dir *'
>>> supcmd = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
>>> print supcmd.communicate()[0]

• run the python script like python shell :

>>> import sys
>>> import subprocess
>>> pid = subprocess.Popen([sys.executable, "calc.py"])

Using pip into shell to install and use pymunk.

The tutorial for today will show how to use pip into the python shell to install a python package.
The first step is shown in the next image:

The Google Cloud SDK - part 002 .

The next part of my tutorials about the Google Cloud SDK comes with some info about the project.
As you know I used the default sample app engine hello word standard application.
The goal is to understand how it works by working with Google's documentation and examples.
Into this project folder we have this files:

08/17/2017  11:12 PM                98 app.yaml
08/17/2017  11:12 PM               854 main.py
08/17/2017  11:12 PM               817 main_test.py

Let's see what these files contain:
First is app.yaml and come with:

runtime: python27
api_version: 1
threadsafe: true

handlers:
- url: /.*
  script: main.app

The next is main.py file:

import webtest

import main


def test_get():
    app = webtest.TestApp(main.app)

    response = app.get('/')

    assert response.status_int == 200
    assert response.body == 'Hello, World!'

The app.yaml file is used to configure your App Engine application's settings of the project.
You can have many application-level configuration files (dispatch.yaml, cron.yaml, index.yaml, and queue.yaml).
This all type of configuration files are included in the top level app directory ( in this case: hello_world).
Let's see some common gcloud commands:

• gcloud app deploy  --project XXXXXX - deploy your project;
• gcloud app browse - show your project running into your browser;
• gcloud components list - show all available components;
• gcloud components update - update all gcloud components;
• gcloud projects list --limit=10 - show all projects with a limit number;

Let's test some changes:
First, change the text from main.py file with something else:

self.response.write('Hello, World!')

Now use this commands:

C:\Python27\python-docs-samples\appengine\standard\hello_world>gcloud app deploy
C:\Python27\python-docs-samples\appengine\standard\hello_world>gcloud app browse

The result is shown in your browser.
You can read about this files into google documentation page - here.
Also some gcloud commands and reference you can read here.

The Google Cloud SDK - part 001 .

This tutorial will cover this steps into development with Google Cloud SDK and Python version 2.7:

• install the Google Cloud SDK on the computer;
• make settings online for your Google project to use Google Cloud SDK;
• run the online project of Google Cloud SDK;
• make setting into your computer to run the local project ;

First, you need to download the Google Cloud SDK and run it.


After GUI install a window command will ask you to set the default project for your work.

Welcome to the Google Cloud SDK! Run "gcloud -h" to get the list of available commands.
---
Welcome! This command will take you through the configuration of gcloud.

Your current configuration has been set to: [default]

You can skip diagnostics next time by using the following flag:
  gcloud init --skip-diagnostics

Network diagnostic detects and fixes local network connection issues.
Checking network connection...done.
Reachability Check passed.
Network diagnostic (1/1 checks) passed.

You must log in to continue. Would you like to log in (Y/n)?  Y

The next step is to start online to deploying a Hello World app with: Deploy a Hello World app:

This will start an online tutorial into the right area of the screen with all commands and steps for your Google Cloud SDK online project.
Follow this steps and in the end will see how the online Google Cloud SDK project will show: Hello, World! into your browser.
The next step is to make a local project and run it.
You can use the python docs sample from GoogleCloudPlatform but is not the same with the online example.
To download the GoogleCloudPlatform sample use git command:

C:\Python27>git clone https://github.com/GoogleCloudPlatform/python-docs-samples
Cloning into 'python-docs-samples'...

Resolving deltas: 100% (6408/6408), done.

C:\Python27>cd python-docs-samples/appengine/standard/hello_world

To start this sample into your google project you need to use this:

C:\Python27\python-docs-samples\appengine\standard\hello_world>gcloud app deploy app.yaml --project encoded-metrics-147522
Services to deploy:

descriptor:      [C:\Python27\python-docs-samples\appengine\standard\hello_world\app.yaml]
source:          [C:\Python27\python-docs-samples\appengine\standard\hello_world]
target project:  [encoded-metrics-147522]
target service:  [default]
target version:  [20170817t234925]
target url:      [https://encoded-metrics-147522.appspot.com]


Do you want to continue (Y/n)?  Y

Beginning deployment of service [default]...

You can stream logs from the command line by running:
  $ gcloud app logs tail -s default

To view your application in the web browser run:
  $ gcloud app browse

C:\Python27\python-docs-samples\appengine\standard\hello_world>gcloud app browse
Opening [https://XXXXXX.appspot.com] in a new tab in your default browser.

C:\Python27\python-docs-samples\appengine\standard\hello_world>

This will start your application with the text - Hello, World! into your browser address bar with this web address: XXXXXX.appspot.com.
