when I locally unzip and train it works — but im not rich I like the access ultralytics give you for very high end gpus and the interface is amzzzzzzzinngggg

GOOD JOB ON THE NEW PLATFORM site

GOOD JOB!

**look i didnt upload 300,000 images, just 5000 , and each file is 9kb**

LLM PROMPT IDEA````

give me a service idea for a service where you ingest ZIP or TAR files and , make them a dataset

should allow large dataset of 30,000 files , should allow jobs of a lot of users —

think like a UNIX WIZZARD you are an expect with bash and pipelines —

List 5 common issues before in the plan , and to avoid it

Hey would you like to share this part of the system like , the unzipping part —

you should embrace LLM ideas — you can use like a Jobs style thing —

again 20,000 dataset isnt a 400,000 image dataset (which isnt uncommon for a YOLO style model )
