$ sudo apt install python3-dev

$ sudo apt-get install build-essential -y

Installing Python with multiple environments

Step 1:

download python.org/downloads/

Step 2:

setup a directory to install Python via the command line

"mkdir python3ver" for the python binaries

and "mkdir pythonProjects" for the python projects

Step 3:

during the installation 

setup the install folder to python3ver\py3111\

then press 'install'

step 4:

via the command line go to pythonProjects

then type

python -m venv my_new_env

once it is done

tree my_new_env

to see the result

Step 5:

To activate the environment

Inside the PythonProjects folder

type

My_new_env\Scripts\activate

the prompt then will change showing (My_new_env)

from there Python can be launched.

To deactivate the environment

just type 'deactivate'

How to use COBE with Python 3.8

After installing Cobe - see previous post entry

here is an example of what you can do:

$ python3
Python 3.8.3 (tags/v3.8.3:6f8c832, May 13 2020, 22:20:19) [MSC v.1925 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import cobe.brain
>>> cobe.brain.Brain.init('test.brain')
>>> test=cobe.brain.Brain('test.brain')
>>> test.learn('this is a test!')
>>> print(test.reply('what is this?'))
this is a test!
>>>

Installing Markov COBE on Windows 10

Cobe is a nifty python module Markov chain based text generation library and MegaHAL style chatbot 

the Linux installation is a breeze (easy as pie)

but on Windows 10 it is a bit tricky

Assuming you are using MINGW32 as environment for your python development - here is what needs to be done:

> git clone https://github.com/pteichman/cobe.git
> winpty python setup.py install
> pip install cython
> winpty python -m pip install --upgrade pip
> python -m pip install -U pip setuptools 

from this point all the items needed are installed 

Next step requires the installation of VisualStudio (vs2019 modules) https://visualstudio.microsoft.com)
Once the installer is downloaded use the 2 first options

MSVC v142 - VS 2019 C++ x64/x86 Build Tools (v14.27)

Kit SDK Windows 10 (10.0.18362.0)

And after this is done 

go to your cobe installation directory and finalize the install

> winpty python setup.py install
