Hi @bglaenger, if you use PyTorch to train the classifier from https://github.com/dusty-nv/jetson-inference/blob/master/docs/pytorch-transfer-learning.md, you can put your images in a directory format like so:
‣ train/
• class-A/
• class-B/
• ...
‣ val/
• class-A/
• class-B/
• ...
‣ test/
• class-A/
• class-B/
• ...
where class-A, class-B, ect. are the names of your image classes (e.g. cat, dog, ect.)
See here for more info about the directory structure of classification dataset: https://github.com/dusty-nv/jetson-inference/blob/master/docs/pytorch-collect.md
