By following this steps you will be able to work with Jupyter Notebooks using Python3 in Windows.

Installing python3:

Download the desired python version from download page (I use 3.6.3)

• https://www.python.org/downloads/

• To check python is correctly installed just go to Windows cmd and type python. You will see something like this:

C:\Users\vperezb>python
Python 3.6.3 (v3.6.3:2c5fed8, Oct  3 2017, 17:26:49) [MSC v.1900 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>

Then type exit() so we can continue installing.

Install virtualenv

Now with pip3 install virtualenv proceed to install virtualenv:

Example with output:

C:\Users\vperezb>pip3 install virtualenv
Collecting virtualenv
  Downloading virtualenv-15.1.0-py2.py3-none-any.whl (1.8MB)
    100% |████████████████████████████████| 1.8MB 610kB/s
Installing collected packages: virtualenv
Successfully installed virtualenv-15.1.0

Create and activate virtualenv

Create enviroment

Go to the path where you want to create the enviroment, so type: (In my case I will place it in C:\Users\vperezb\Documents)

cd C:\Users\vperezb\Documents

Then type: virtualenv nameenv to create a enviroment named nameenv.

(This will create an enviroment with the version we already installed. If you want to create an enviroment with another python version already installed check this post: https://vperezb.github.io/Use-specify-different-Python-version-with-virtualenv-enviroment/)

Example with output:

C:\>cd C:\Users\vperezb\Documents
C:\Users\vperezb\Documents>virtualenv nameenv
Using base prefix 'c:\\users\\vperezb\\appdata\\local\\programs\\python\\python36-32'
New python executable in C:\Users\vperezb\Documents\nameenv\Scripts\python.exe
Installing setuptools, pip, wheel...done.

Activate enviroment

Now we only need to activate the enviroment by following this steps.

• cd nameenv/Scripts
• activate
• cd ../..

Example with output:

C:\Users\vperezb>cd C:\Users\vperezb\Documents
C:\Users\vperezb\Documents>cd nameenv/Scripts
C:\Users\vperezb\Documents\nameenv\Scripts>activate
(nameenv) C:\Users\vperezb\Documents\nameenv\Scripts>cd ../..
(nameenv) C:\Users\vperezb\Documents>

Now we are in the enviroment so any lib we install will be installed inside it. Look how:

Installing Jupyter Notebook lib

Type pip3 install jupyter notebook.

Example with output:

(nameenv) C:\Users\vperezb\Documents>pip3 install jupyter notebook
Collecting jupyter
  Downloading jupyter-1.0.0-py2.py3-none-any.whl
(...

(nameenv) C:\Users\vperezb\Documents>

Start Jupyter Notebook:

Now if we want to start jupyter notebook we only need to go to the desired path and type jupyter notebook.
