Extra Windows Instructions

For Windows, when you install
Anaconda, choose to also install
Anaconda Prompt.
This will make everything easier.

Create Virtual Environment for Data-X
• Open Terminal
• Run the command:
conda create -n data-x python=3 anaconda
To activate Virtual environment:
source activate data-x
on Windows: activate data-x
To deactivate Virtual environment:
source deactivate
on Windows: deactivate

OPTIONAL: Create Virtual Environment
(e.g. for Python 2.7)
We have chosen to work with Python 3.6 in this class, however it is easy to
also install a Python 2.7 Virtual Environment(if you’d ever need it)
• Open Terminal
• Run the command:
conda create -n py2 python=2 anaconda
To activate the Python 2.7 Virtual environment:
source activate py2
on Windows: activate py2
To deactivate (any) Virtual environment:
source deactivate
on Windows: deactivate

Please note, many functions, modules and libraries differ between Python 2.x and Python 3.x (Python 3 is not
backwards compatible). However, many scripts / notebooks can be compatible with both Python 3 and Python
2 by running the code below first in your script / notebook:
from __future__ import absolute_import, division, print_function

Before you install packages or run a notebook
Always Activate the Virtual Environment first!
(This way you will never run into problem with crashing your root Python / Anaconda installation)

Run:
source activate data-x
(on Windows: activate data-x)

every time you open a new terminal window.

The word within the parenthesis at the start of every line in the command
prompt indicate what Virtual Environment you have activated

How to Install packages into your Virtual Environment
Anaconda comes with many packages pre-installed, but if you
want to install additional packages (or update existing ones)
you can run:
Install a package by running:
conda install [package name]

Install packages by running:
conda install [pkg1] [pkg2] [pkg3]

Data

X

Required packages
The packages you need can be installed by running the
command below:

Install a package by running:
conda install tensorflow keras html5lib py-xgboost

Data

Installing packages not available via conda
Some packages are not available via conda, instead you can
visit https://anaconda.org/ (Anaconda Cloud, a package
management service) and search for the package you want
to install. Here you can usually find any Python package for
your specific machine settings.
Install a package by (for example) running:
conda install -c conda-forge tensorflow

Run your first notebook
Anaconda comes with Jupyter notebooks which we will work with a lot.
In order to run your first Jupyter notebook, open the terminal, source your Virtual
Environment, cd t into the specific working directory and then run the comMand
jupyter notebook a new browser window with your current directory will
open and you can either create a new notebook or open an existing one.
