List of experiment runs, with little checkboxes

For my personal projects, I found a place between “boring print statements that are easy to code” and “pretty GUI web app that requires a lot of set-up.” Even without reaching for curses, there are some neat things you can do with Python’s print statement!

I used this last week for a school project that involved training a bunch of TensorFlow models. I threw together a script to help view results.

Disclaimer: Because I use this for personal scripts, I’m cheating here by not worrying about compatibility on devices I’m not using. Your results might vary!

Terminal Colors

I can change the color of text in the terminal by adding a little weird character before and after the text I want to change. There are also options for bold or underlined text.

print('\033[1m{}\033[0m'.format('This text is bold!'))

Here’s more details on how to do this in Python.

For the deep learning experiments, I used it to highlight the epoch with the best validation accuracy in my experiment results.

One thing is that copy-pasting doesn’t take the formatting with it, which is why I also print an asterisk.


With scripts I run often, I sometimes figure out the error message by the shape of the text block anyway. Inspired by Homebrew, I sometimes print out emoji/Unicode in my scripts. I started throwing in emojis, like 🔥, to tell me when things broke or not.


My terminal messes up the spacing, but this is a hacky script that hopefully will never see the light of day, so I just added spaces.

For the deep learning experiments, I used it in my recent experiment list to mark which experiments had reached their early-stopping criteria.
