Python : Open3D cannot be used on Windows 10 and Fedora Linux Distro .

Open3D is an open-source library that supports rapid development of software that deals with 3D data. The Open3D frontend exposes a set of carefully selected data structures and algorithms in both C++ and Python. The backend is highly optimized and is set up for parallelization. Open3D was developed from a clean slate with a small and carefully considered set of dependencies. It can be set up on different platforms and compiled from source with minimal effort. The code is clean, consistently styled, and maintained via a clear code review mechanism. Open3D has been used in a number of published research projects and is actively deployed in the cloud. We welcome contributions from the open-source community.

Today I tested this python package with Windows 10 and Fedora Linux Distro with python versions 11 and 10 ...

This package does not work and you will see why ...

CMake Deprecation Warning at CMakeLists.txt:189 (cmake_policy):

  The cmake-policies(7) manual explains that the OLD behaviors of all

  specific short-term circumstances.  Projects should be ported to the NEW
  behavior and not rely on setting a policy to OLD.

...

According to this issue number 4796 and my test on Windows 10 with a Python version greater than 10 and on Fedora Linux Distro you cannot use this python package.

You can try an older version of Python and try it, see this example:

C:\PythonProjects\Open3D001>C:\Python310\python.exe -m pip install --user open3d --no-warn-script-location
C:\PythonProjects\Open3D001>C:\Python310\python.exe -c "import open3d as o3d; print(o3d)"
Traceback (most recent call last):

...

Basically, this python package cannot be used with an old python version in Windows 10.

Simple install of python in Windows O.S.

Today I create this simple video tutorial for new python users.

In this video tutorial I show you how easy is to install the python programming language in Windows O.S.

After install you can use the command python and you can use the python shell to test this programming language.

Also, you can create a script file with any name.

for example name the file: test.py and run in the windows shell with: python test.py.

You can see this video tutorial on my youtube account.

The development with python-instagram - python 3.6.3 .

Today I will show you how to deal with Instagram API using python-instagram python module.
The version of the python I used is this version: Python 3.6.3 |Anaconda custom (64-bit)| (default, Oct 15 2017, 03:27:45) [MSC v.1900 64 bit (AMD64)] on win32
This is the python install of PyCharm IDE - Miniconda3 on my Windows 10 account.
The first step is the install module with the pip tool:

pip install python-instagram

The next step is to take your Client Secret and Client ID from your Instagram account:
The next step is to set your Instagram API:

You can try some example from here.
I just got this error :...instagram.bind.InstagramAPIError: (400) OAuthAccessTokenException-The access_token provided is invalid.
I think the problem is Instagram because I search on the internet and many people come with this issue.
The team development of Instagram tell us to set some Permission:
All permissions require approval to be used out of Sandbox. Make sure to review our Platform Policies before submitting your app for review. To learn more about the review process, please read the Permissions Review documentation.
I try to use this but is not very clear for me.

     functions). This package does not contain any network protocols.
    Crypto.PublicKey
     Public-key encryption and signature algorithms (RSA, DSA)
    Crypto.Signature
     Public-key signature algorithms (RSA PKCS#1)

PACKAGE CONTENTS
    Cipher (package)
    Hash (package)
    Protocol (package)
    PublicKey (package)
    Random (package)
    SelfTest (package)
    Signature (package)
    Util (package)

DATA
    __all__ = ['Cipher', 'Hash', 'Protocol', 'PublicKey', 'Util', 'Signatu...
    __revision__ = '$Id$'
    __version__ = '2.6.1'

VERSION
    2.6.1

Let's test some examples with this python module.
The first example comes with encrypting and decrypt message based one key.
The key also needs to be one encryption key and fix to key32.
The iv will not be specified by the user, it will be generated and then encrypted with RSA.
NEVER make the IV constant and unique, it must be unique for every message.
Let's see the example source code:

from Crypto.Cipher import AES
from Crypto import Random
def encrypt(key32,message):
    cipher=AES.new(key32,AES.MODE_CFB,iv)
    msg=cipher.encrypt(message)
    print(msg)
    return msg
def decrypt(key32,msg):
    dec=AES.new(key32,AES.MODE_CFB,iv)
    return dec.decrypt(msg).decode('ascii')
if __name__=='__main__':
    global iv
    iv=Random.new().read(AES.block_size)
    key='free-tutorials.org'
    key32 = "".join([ ' ' if i >= len(key) else key[i] for i in range(32) ])
    message='another website with free tutorials'
    enc =encrypt(key32, message)
    print enc
    print(decrypt(key32,enc))

The resulting output is this:
ﾰ Cﾣﾟ2 ﾶÕ|ýXÍ ﾲNäÇ3ﾖﾞLﾏﾫuï: ù ﾒNﾰm
ﾰ Cﾣﾟ2 ﾶÕ|ýXÍ ﾲNäÇ3ﾖﾞLﾏﾫuï: ù ﾒNﾰm
another website with free tutorials
Another more simplistic example:

from Crypto.Cipher import AES
from Crypto import Random
key = b'Sixteen byte key'
iv = Random.new().read(AES.block_size)
cipher = AES.new(key, AES.MODE_CFB, iv)
msg = iv + cipher.encrypt(b'Attack at dawn')

See the output of variables:

>>> print key
Sixteen byte key
>>> print iv
ÔÄ▀DÒ ÕØ} m║dÕ╚\
>>> print cipher.encrypt(b'Attack at dawn')
åÌ£┴\u\ÍÈSÕ╦╔.

Using MD5 example:

>>> from Crypto.Hash import MD5
>>> MD5.new('free text').hexdigest()
'be9420c1596a781119c53a9933a8234f'

Using RSA key example:

>>> from Crypto.PublicKey import RSA
>>> from Crypto import Random
>>> rng = Random.new().read
>>> RSAkey = RSA.generate(1024, rng)
>>> public_key = RSAkey.publickey()
>>> print public_key
<_rsaobj e="" n="" x3650b98="">
>>> enc_data = public_key.encrypt('test data', 32)[0]
>>> print enc_data

NVIDIA python module Theano.

I try to use python module Theano.
First I install this python module.
C:\WINDOWS\system32>cd C:\Python27

C:\Python27>cd Scripts

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

Installing collected packages: Theano
Running setup.py install for Theano ... done

When I try to used I got this error:
import theano
WARNING (theano.configdefaults): g++ not detected ! Theano will be unable to execute optimized C-implementations (for both CPU and GPU) and will default to Python implementations. Performance will be severely degraded. To remove this warning, set Theano flags cxx to an empty string.
I try to fix that error, but I don't find any solution.
This python module work. I tested with examples from NVIDIA, see:
