Installing Demyst's Libraries
These sets of guides are going to help you get started discovering, exploring and operationalizing new external data products through Demyst's extensive Python libraries. But if you'd rather discover and access data through our web interface, feel free to head over to the Demyst Console.
Before we get started we need to make sure you've got Python 3.5 or a higher version running in your environment and successfully been given access to an account through our website. If you don't, check out how to do the Python Installation.
The Demyst Analytics Python package is going to change the way you access external data. The toolkit is not limited to interactive analysis. The Python package can also be used in production data pipelines.
Let's get started!
First open up a Terminal or Command Prompt and type the following. You may need to use
pip3 depending on your environment:
pip install demyst-analytics
note – What is with the extra arguments to pip? The current analytics package is a pre-release version and is only publish on PyPi test packaging systems.
Many of the tutorials here assume you have Jupyter Notebooks installed. While Jupyter is not necessary to use the analytics package the tutorials assume you have it running.
pip install jupyter
To see if it is working, run:
You can launch it with:
This should open up your default web browser to the Jupyter file browser. To create a new Notebook, click on the New button and select Python3:
Now you should see your first Notebook:
Demyst Data Function's are written in Python (>3.6). Before we get started let's see if your environment is ready for the Demyst libraries. In a Terminal (Mac) or a Command Prompt (Windows) run the following command:
If that doesn't work you should also try:
Either should product something like this:
As long as that number is greater than
3.6 you are ready to go.
If you don't have the right version of Python installed, don't worry! The rest of this guide will help you get there. If at any point you get to stuck head over to our support page.
Currently, Demyst supports OS X High Sierra and later, but these instructions will likely work for older versions.
The best way to get the latest version of Python running on your Mac is through Homebrew. Homebrew makes it easy to install open-source software on your Mac.
Make sure your PATH is properly set to use the binaries Homebrew will install:
Now install the latest version of Python3:
brew install python3
You can verify it installed correctly by running the following command:
Currently Demyst supports Windows 7 and greater.
Choco is a package manager that helps reliably install and configure open source software on Windows.
Anaconda is a popular distribution of Python for Mac. Any version supporting Python 3.6 or greater should work fine.
Installation instructions for Anaconda on Windows can be found here.
