As part of updates to arachn.io, I’ve started tinkering with object detection machine learning models. During my experiments on AWS SageMaker, I found that AutoPilot does not support object detection models, so I had train using notebooks. As a result, I hit some “gotchas” fine-tuning TensorFlow Object Detection models. While this notebook works a treat on its own training data (at least when run through SageMaker studio), this discussion will focus on things I learned while trying to run it on my own data on August 31, 2024.

I was investigating the feasibility of putting natively-formatted Twitter data into BigQuery, and got pretty far along the way before deciding to go another direction. I found the schema in the twitter-for-bigquery project to be incomplete for my needs, so I made a new schema of my own. I’m making the schema available here in case it’s of use to anyone else.
