How to install PyGrib with ECCodes (Python 3.6.5, Ubuntu 19, 18, 16, RHEL, Lambda, Linux AMI, Docker)

[ last_updated: 07-JAN-2020 ]

Recently I've had to work with Meterological data of the GRIB format. Needless to say, if you're reading this, you probably know how hard it is to get a library that can read them and even harder, setting up those libraries. Pygrib for python is by far the best library for reading grib files but the installation can leave you dizzy

In this tutorial I use Ubuntu 18 and python 3.6.5 virtualenv. Note: You don't have to use virtualenv Python. You can just as well use your system Python 3 however I personally find virtualenv a clean way to deal with these kind of complicated setups (prevents me mucking up my system's Python). This setup should also work with lower and higher Ubuntu versions (as someone below mentioned) and other Linux distros (like RHEL - AWS Linux AMI etc). The key to this installation is to build eccodes correctly (for your machine architecture) and succe

How to Keep Pull Requests Manageable

• There are a lot different things you can try to keep pull requests manageable.
• These pointers are not meant to be rules, but merely guidelines when possible. Due to the nature of what you are working on, some of these techniques may not be possible (or incredibly difficult).

• Either way, here are some tips to help make people not want to claw their eyes out reviewing a pull request.

The Basics

• These are the fundamental basics to a pull request and ALL pull requests should have these, regardless of how small or meaningless it is.
