Hi, I'm unable to find the requested changes. Is there anything I should do?

Can you see the conversation under line 114?

OK, as I understand it, I should add code to install pandas and seaborn. Should I create a new pull request or is there a way to update this one with a few lines of code? I think all I'm adding is:

import subprocess
import sys

def install(package):
    subprocess.call([sys.executable, "-m", "pip", "install", package])
    
install("pandas")
install("seaborn")

you just need to push to your branch and it will be automatically reflected here.

I tried updating the file here on GitHub - could you tell me if it works now?

@raokaran Sorry I wasn't clear that the installation is a backend thing that needs to be done in the .travis.yml file. Unfortunately it's a bit complicated. I see three options here:

1. Take out the examples that involve Python libraries. reticulate works fine with bookdown + Travis + GitHub Pages with no libraries, for example: https://jtr13.github.io/githubpagestest/methods.html#adding-another-language

2. Rather than try to include your full tutorial in this bookdown book, host it on your GitHub repo using output: github_document and then provide a link to the rendered .md file and short description here. Here's an example of an .Rmd with this output format:
   https://github.com/jtr13/codehelp/blob/master/R/gather.Rmd
   and the rendered .md file: https://github.com/jtr13/codehelp/blob/master/R/gather.md

3. On the backend, the maintainers can try to add the libraries to .travis.yml. I made some headway but got stuck on some Python 2 vs. 3 issues. This SO post might be useful: https://stackoverflow.com/questions/27644586/how-to-set-up-travis-ci-with-multiple-languages

@skyetim What do you recommend?

[skyetim]

I recommend the 2nd option as it's easier for @raokaran to implement.

[raokaran]

Hi, I tried the second option. Could you tell me if it turned out alright?

[skyetim]

It works now! 🎉 Thanks for your contribution. It has been merged!

Thank you!
