Efficient MultiModal Data Pipeline
You’ve got everything ready – data, model, a beefy GPU setup. You hit “run” and… wait. And wait some more. Your GPUs are barely breaking a sweat while your wallet’s getting lighter by the hour.
Sound familiar? We’ve been there. After some detective work on our nanoVLM project, we discovered the real culprit wasn’t our model or hardware, it was our data pipeline being incredibly wasteful.
Here’s what we found:
- Idle GPUs: Our model was literally waiting around for data to show up
- Padding hell: Every batch was stuffed with useless padding tokens that contributed
