Hi trying again to use fine tuning process for creating my checkpoint, all paths in the settings has been correctly entered, meta_Cap.json / meta_lat.json correctly generated etc... really dont know where the error come from :( Thanks

Have you tried switching to us a dataset toml config file instead of the old folder based image finetuning? Load the test example and study how the dataset timl file work. Might be the key to make this work:

./test/config/finetune-AdamW-toml.json

it use this dataset toml config file:

./test/config/dataset-finetune.toml

Modify the config and toml dataset file to suit your needs
