Fixed Python Notebook Examples #226

MarkFischinger · 2024-04-10T13:31:59Z

I'm excited to share some updates I've made to the Python notebook examples. While browsing through the existing examples because of #224, I noticed a few issues that had to be fixed.
Along with correcting typos, updating for the latest mlpack API changes as well as some other bug fixes, I've ensured all python notebooks are now fully functional by running and fixing each one :)

Once I have some more time, I plan to extend these fixes to the notebooks in other languages too.

It seems like meanDates isn't used anywhere else (correct me if I'm wrong), maybe we can just remove this cell?

If you had any issues, I can put the CSV also on datasets.mlpack.org. Looks like maybe there was an SSL failure? But everything seems to load correctly for me.

I put it up on https://datasets.mlpack.org/breast-cancer-wisconsin.csv, which shouldn't have an SSL issue, want to update the link to there?

Did you mean to add this notebook? It looks new, I guess an adaptation of the C++ version?

Reply via ReviewNB

@rcurtin yes, I thought it would be a great addition since most of the notebook examples have a C++ and Python version.

I just saw Whiplash a few weeks ago (number 24 on the list), I didn't realize it was so old. I thought it was a great movie.

Haven't seen it yet, but I’ll definitely check it out on your recommendation when I have the chance ;)

I wonder if it would be possible to use mlpack.preprocess_split() and mlpack.preprocess_scale() here instead, but, don't feel obligated to look into it, it's just a passing thought.

rcurtin

Wow, this is absolutely great! Thank you for taking the time to go through all of these @MarkFischinger. I wish that we had an automated way to keep things up to date, but I think we don't have any CI job that tests the notebooks. All of my comments are pretty minor, really the main one is about the SSL verification---I think it shouldn't be needed, was there a certificate issue?

MarkFischinger · 2024-04-11T14:51:44Z

@rcurtin Yes, I encountered a slight issue with SSL verification while requesting lab.mlpack.org. The error I ran into was: URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1007)>.

My current approach is a workaround to this problem. However, I agree that the ideal solution would be to update the SSL certificate on the website.

rcurtin · 2024-04-22T20:41:15Z

I went through and added the datasets to datasets.mlpack.org, so now we can use that instead to avoid the SSL error. Can you make those changes? If so I think this is good to go. 👍

MarkFischinger · 2024-04-22T22:28:56Z

@rcurtin I removed all SSL certificate exceptions, tested it, and everything seems to be working fine now :)

Looks great, thanks again! 👍
