Bring your feature branch up to date with master. Deploying from Git branches adds flexibility. Bring your branch up to date with master and deploy it to make sure everything works. If everything looks good the branch can be merged. Otherwise, you can deploy your master branch to return production to its stable state.

Updating a feature branch

First we'll update your local master branch. Go to your local project and check out the branch you want to merge into (your local master branch)

$ git checkout master

Fetch the remote, bringing the branches and their commits from the remote repository. You can use the -p, --prune option to delete any remote-tracking references that no longer exist in the remote. Commits to master will be stored in a local branch, remotes/origin/master

Install Anaconda on Windows Subsystem for Linux (WSL)

Thanks everyone for commenting/contributing! I made this in college for a class and I no longer really use the technology. I encourage you all to help each other, but I probably won't be answering questions anymore.

This article is also on my blog: https://emilykauffman.com/blog/install-anaconda-on-wsl

Note: $ denotes the start of a command. Don't actually type this.

Steps to Install Anaconda on Windows Ubuntu Terminal

  1. Install WSL (Ubuntu for Windows - can be found in Windows Store). I recommend the latest version (I'm using 18.04) because there are some bugs they worked out during 14/16 (microsoft/WSL#785)
  2. Go to https://repo.continuum.io/archive to find the list of Anaconda releases
  3. Select the release you want. I have a 64-bit computer, so I chose the latest release ending in x86_64.sh. If I had a 32-bit computer, I'd select the x86.sh version. If you accidentally try to install the wrong one, you'll get a warning in the terminal. I chose `Anaconda3-5.2.0-Li

Returns the contents of `df` as a local `pandas.DataFrame` in a speedy fashion. The DataFrame is
repartitioned if `n_partitions` is passed.
