 - `the-stack-v2-train-full`: contains the training data with 600+ programming languages used to train StarCoder2-15B  with the files concatenated per repository
 - `the-stack-v2-train-full-files`: same as `the-stack-v2-train-full` but without repository concatenation which makes filtering files or licenses easier
 - `the-stack-v2-train-smol`: contains the training data with 17 programming languages used to train StarCoder2-3B and 7B  with the files concatenated per repository
