Hi @thurac2022 ! Because this version of The Stack is grouped by repository (to train with repo context), filtering by language is only possible on the fly, e.g.:

ds = load_dataset("bigcode/the-stack-v2-train-smol-ids", streaming=True, split="train")

# In a loop:
for sample in iter(ds): 
    for file in sample["files"]:
        if file["language"]:
            ...

# Or with .map():
ds = ds.map(your_language_filtering_function)

With streaming=True you don't actually download the whole dataset locally.

Also, the bigger datasets like https://huggingface.co/datasets/bigcode/the-stack-v2-dedup have a flat flat structure, so you can do:

# specific language (e.g. Dockerfiles)
ds = load_dataset("bigcode/the-stack-v2-dedup", data_dir="data/Dockerfile", split="train")

@anton-l I get the exception when use the aws download script:
